12.1 Power supply and tariffsAccording to current Federal tariffs [Germany], the electrical demand for heat pumps is considered domestic usage. Where heat pumps areused to heat buildings, the local power supply company must first givepermission [check with your local power supply company].Check the connection conditions specified by your local power supplyutility for the stated equipment details. It is crucial to establish whethera mono-mode and/or mono-energetic heat pump operation is feasiblein the supply area.

It is also important to obtain information about standing charges andenergy tariffs, about the options for utilising off-peak electricity duringthe night and about any power-off periods.Address any questions relating to these issues to your customer's localpower supply utility.

Application procedureThe following details are required to assess the effect of the heat pumpoperation on the grid of your local power supply utility:■ User address■ Location where the heat pump is to be used■ Type of demand in accordance with general tariffs

(domestic, agricultural, commercial, professional and other use)

■ Intended heat pump operating mode■ Heat pump manufacturer■ Type of heat pump■ Connected load in kW (from rated voltage and rated current)■ Max. starting current in A■ Max. heat load of the building in kW

12.2 Installation requirements■ The installation room must be dry and safe from the risk of frost.■ Never install the appliance in living spaces or directly next to, below

or above quiet rooms/bedrooms.■ In conjunction with an ice store system:

Never site in rooms containing washing machines or dryers.■ Maintain the minimum clearances and minimum room volume (see

the following chapter).■ Sound insulation measures:

– Reduction of reverberative surfaces, particularly on walls and ceil-ings. Rough structural renders absorb more sound than tiles.

– If quietness is a particularly important consideration, apply sound-absorbing material to the walls and ceilings (commercially availa-ble).

– We recommend you never install this device on wooden floors inthe roof space, to prevent the transmission of structure-bornenoise.

– The doors of the installation room should correspond to at leastemission protection category E1. This is usually achieved by fittingtubular chipboard doors.

■ Hydraulic connections:– Always make hydraulic heat pump connections flexible and stress-

free (e.g. by using Viessmann heat pump accessories).– Apply anti-vibration fixings to pipework and installations.– To prevent condensation, thermally insulate lines and components

in the primary circuit with vapour diffusion-proof materials.– Provide corresponding installation areas for accessories and

expansion vessels on the brine side.

12.3 Electrical connections for central heating and DHW heating■ Observe the technical connection requirements specified by your

local power supply utility.■ Your local power supply utility will provide you with details regarding

the required metering and switching equipment.■ We recommend the provision of a separate electricity meter for the

heat pump.

Viessmann heat pumps operate with 400 V~. In some countries,230 V models are also available.The control circuit requires a power supply of 230 V~.The control circuit fuse (6.3 A) is located in the heat pump controlunit.

Power-OFFIt is possible for the power supply utility to shut down the compressorand instantaneous heating water heater (if installed). The ability tocarry out such a shutdown may be a power supply utility requirementfor providing a lower tariff.

This must not shut off the power supply to the heat pump controlunit.

Arrangement of drain line for safety valve

Provide a drain line to drain safety valve A on the heating side.

12.7 Sizing the heat pumpNoteSizing is of particular relevance to heat pump systems that are to be operated in mono mode, since oversized equipment will incur disproportionatesystem costs. Therefore avoid oversizing!

First establish the standard heating load of the building ΦHL. For dis-cussions with customers and for the preparation of a quotation, in mostcases estimating the heat load is adequate.

As with all heating systems, determine the standard heat load of thebuilding to EN 12831 before ordering the appropriate heat pump.

Mono mode operation

To EN 12831, the heat pump system in mono mode must, as sole heatsource, be able to cover the entire heat demand of the building.

When sizing the heat pump, observe the following:■ Take supplements to the heat load of the building to cover power-

OFF periods into account. [In Germany] the power supply utility mayinterrupt the power supply of heat pumps for up to 3 × 2 hours withina period of 24 hours.Observe additional individual arrangements for customers with spe-cial tariffs.

■ The building inertia means that 2 hours of power-OFF time are nottaken into consideration.

NoteHowever, the "enable time" between power-OFF periods must be atleast as long as the preceding power-OFF time.

Estimate of the heat load based on the heated areaThe heated surface area (in m2) is multiplied by the following specificheat demand:

Passive house 10 W/m2

Low energy house 40 W/m2

New build (to EnEV) 50 W/m2

House (built prior to 1995 with standard thermal insu-lation)

80 W/m2

Older house (without thermal insulation) 120 W/m2

Theoretical sizing with the power-OFF for 3 × 2 hoursExample:For a new building with good thermal insulation (50 W/m2) and aheated area of 170 m2

■ Estimated heat load: 8.4 kW■ Maximum power-OFF time 3 × 2 hours at a minimum outside tem-

perature to EN 12831

24 h, therefore, result in a daily heat volume of:■ 8.4 kW ∙ 24 h = 202 kWh

To cover the maximum daily heat amount, only 18 h/day are availablefor heat pump operation on account of the power-OFF periods. Thebuilding inertia means that 2 hours of the period during which poweris blocked are not taken into consideration.■ 202 kWh / (18 + 2) h = 10.1 kW

In other words, the heat pump output would need to be increased by20 % if power-OFF was to be applied 3 × 2 hours per day.Frequently, power-OFF periods are only invoked if there is a need todo so. Please contact the customer's power supply utility to enquireabout power-OFF periods.

Mono energetic operationIn heating mode, the heat pump system is supported by an instanta-neous heating water heater. The control unit switches the instantane-ous heating water heater on, subject to the outside temperature (dualmode temperature) and heat load.

NoteThat part of the electric power drawn by the instantaneous heatingwater heater will generally not be charged at special tariffs.



5822

541

GB

12

Sizing of typical system configurations:■ Size the heating output of the heat pump to approx. 70 to 85 % of

the max. required building heat load to EN 12831.■ The heat pump covers approx. 95 % of the annual heat load.■ Blocking periods do not need to be taken into consideration.

NoteThe reduced size of the heat pump, compared to mono mode opera-tion, means that the runtime will increase. To compensate for this,increase the size of the heat source for brine/water heat pumps.For a geothermal probe system, the annual extraction rate must notexceed 100 kWh/m ∙ p.a.

Instantaneous heating water heaterAn electric instantaneous heating water heater can be integrated in theheating water flow as an auxiliary heat source. The instantaneousheating water heater is installed in the appliance, and connected andprotected via a separate power supply.The heat pump control unit regulates this function. The instantaneousheating water heater can be enabled separately for central heating andDHW heating.

If enabled by the respective parameter, the heat pump control unitstarts stages 1, 2 or 3 of the instantaneous heating water heater, sub-ject to the prevailing heat demand. As soon as the maximum flow tem-perature in the secondary circuit is reached, the heat pump control unitswitches the instantaneous heating water heater off.Parameter "Stage at power-OFF" restricts the output stage of theinstantaneous heating water heater for the duration of the power-OFFperiod.To limit the total power consumption, the heat pump control unit stopsthe instantaneous heating water heater for a few seconds directlybefore the compressor starts. Each stage is subsequently started indi-vidually one after the other at intervals of 10 s.If the instantaneous heating water heater is on and the differentialbetween flow and return temperatures in the secondary circuit doesnot rise by at least 1 K within 24 h, the heat pump control unit displaysa fault message.

Dual mode operation

External heat generatorThe heat pump control unit enables dual mode operation of the heatpump with an external heat source, e.g. oil boiler.The external heat source is hydraulically connected in such a way thatthe heat pump can also be used as a return temperature raising facilityfor the boiler. System separation is provided with either a low lossheader or a heating water buffer cylinder.For optimum heat pump operation, the external heat source must beintegrated via a mixer into the heating water flow. Direct activation ofthis mixer by the heat pump control unit results in a quick response.If the outside temperature (long-term average) is below the dual modetemperature, the heat pump control unit starts the external heatsource. In the case of direct heat demand from the consumers (e.g.for frost protection or if the heat pump is faulty), the external heatsource is also started above the dual mode temperature.

The external heat source can also be enabled for DHW heating.

NoteThe heat pump control unit does not contain any safety function forthe external heat source. To prevent excessive temperatures in theheat pump flow and return in case of a fault, high limit safety cut-outsmust be provided to stop the external heat source (switching threshold70 °C).

Supplement for DHW heating in mono mode operation

NoteIn dual mode operation of the heat pump, the heating output availableis generally so high that this supplement does not need to be takeninto consideration.

For a general residential building, a max. DHW demand of approx.50 l per person per day at approx. 45 °C is assumed.■ This demand represents an additional heat load of approx.

0.25 kW per person given a heat-up time of 8 h.■ This supplement will only be taken into consideration if the sum total

of the additional heat load exceeds 20 % of the heat load calculatedto EN 12831.

Supplement for setback modeAs the heat pump control unit is equipped with a temperature limiterfor setback mode, the supplement for setback mode to EN 12831 canbe ignored.In addition, the control unit is equipped with start optimisation, whichmeans that there is also no need for a supplement for heating up fromsetback mode.

Both functions must be enabled in the control unit. If any of the sup-plements are omitted because of the activated control unit functionsthen this must be documented when the system is handed over to theoperator.If, irrespective of the above mentioned control options, these supple-ments are nevertheless to be taken into account, the calculation shouldbe made with reference to EN 12831.

12.8 Heat sources for brine/water heat pumps

Frost protectionTo safeguard a trouble-free heat pump operation, use antifreezebased on glycol in the primary circuit. This must protect against frostdown to at least – 15 °C and contain suitable anti-corrosion inhibitors.Ready-mixed solutions ensure an even distribution of concentrate.Recommendation:For the primary circuit, use Viessmann "Tyfocor" heat transfer mediumwhich is based on ethylene glycol (ready-mixed down to -19 °C, lightgreen).

NoteWhen selecting the anti-freeze, always observe the stipulations of theauthorising body.

If the authorising body does not permit inhibitors for corrosion protec-tion, the following measures can be taken to ensure frost protection:■ Use an additional separating heat exchanger (similar to a well circuit

with water/water heat pumps).■ Extend the probe and fill with water.

Geothermal collectorThe thermal properties of the upper layer of the earth, such as thevolumetric thermal capacity and thermal conductivity, are largelydependent on the consistency and properties of the ground.The wetter the soil, the higher the proportion of mineral constituents(quartz or feldspar) of the soil and the smaller the proportion of pores,the better the storage characteristics and thermal conductivity.The specific extraction rate qE for the ground lies between approx. 10and 35 W/m2.

Dry sandy soil qE = 10–15 W/m2

Damp sandy soil qE = 15–20 W/m2

Dry loamy soil qE = 20–25 W/m2

Damp loamy soil qE = 25–30 W/m2

Ground with groundwater qE = 30–35 W/m2

These details enable the required ground area to be calculated subjectto the heat load of the building and the refrigerating capacity ²K of theheat pump.²K = ²WP – PWP

²K is the difference between the heat pump heating output (²HP) andits power consumption (PHP).

Manifolds and headersThe manifold and the header should be installed so that they areaccessible for future inspections, e.g in their own distribution ductsoutside the house or in the basement window duct.Every pipe circuit should be able to be isolated individually on the flowand return side to enable the collector to be filled and vented.

All pipes, profiles etc. must be made from corrosion-resistant materi-als. Flow and return lines transport cold brine (brine temperature <cellar temperature). For that reason, all pipes inside the house and thewall outlets (even inside the wall structure) must be thermally insulatedand vapour diffusion-proof to prevent the formation of condensationand subsequent damage from moisture. Alternatively, a drain can beinstalled to remove condensate. Practical experience has shown thata prepared brine mixture is satisfactory for filling the system.

Pipework should be routed on the outside of the building with a slightslope to prevent ingress of water during heavy rain. A good drainagesystem will ensure that the rainwater drains away.The use of approved wall outlets (e.g. Doyma) is required if the sitemakes specific demands regarding pressing water.

Rough sizingBasis for sizing is the refrigerating capacity ²K of the heat pump atoperating point B0/W35.Required area FE = ²K/³E (average extraction rate subject to groundconditions).

Required number of pipe circuits @ 100 m length subject to FE and thepipe dimension:■ With PE 20 × 2.0:

Pipe circuits @ 100 m length = FE · 3/100■ With PE 25 × 2.3:

Pipe circuits @ 100 m length = FE · 2/100■ With PE 32 × 3.0 (2.9):

Pipe circuits @ 100 m length = FE · 1.5/100

The detailed design depends on the ground structure and can only bedetermined following a local inspection.

The heat pump with a heating output of 5.9 kW (incl. supplement forpower-OFF periods, excl. DHW heating), and a cooling capacity of²K = 4.7 kW corresponds to the required output.

Sizing the geothermal collector■ Average specific extraction rate:

³E = 25 W/m2

■ ²K = 4.7 kW■ FE = ²K/³E = 4700 W/25 W/m2 = 188 m2

■ The number X of required pipe circuits (PE pipe 25 × 2.3) @100 m length results from:X = FE · 2/100 = 200 m2 · 2 m/m2/100 m = 4Selected: Four pipe circuits @ 100 m length (Ø 25 mm × 2.3 mmwith 0.327 l/m)

Required amount of heat transfer medium (VR)■ Take the content of the geothermal collector including all inlet pipes,

plus the volume of fittings and the heat pump into consideration.■ Provide distributors corresponding to the number of pipe circuits.■ The low cooling capacity and the connected length mean that a sup-

ply line of PE 25 × 2.3 is sufficient.■ Supply line: 10 m (2 × 5 m) with PE 32 × 3.0 (2.9)VR = no. of pipe circuits × 100 m × pipeline volume + supply line length

× pipeline volume= 4 × 100 m × 0.327 l/m + 10 m × 0.531 l/m= 130.8 litres + 5.31 litres= 136 litres

Selected: 200 litres (incl. heat transfer medium in the fittings and theheat pump).

Geothermal collector pressure drop■ Flow rate, heat pumps with 5.9 kW: 860 l/h■ Flow rate per pipe circuit = (860 l/h)/(4 circuits per 100 m) = 215 l/h

per pipe circuit■ Δp = R value × pipe length

R value (pressure drop) for PE 25 × 2.3 and 32 × 3.0 (2.9) (see tables"Pressure drop" for the pipelines):■ At 215 l/h ≈ 59 Pa/m■ At 860 l/h = 176 Pa/m

ΔpPipe circuit = 59 Pa/m × 100 m = 5900 PaΔpSupply line = 176 Pa/m × 10 m = 1760 PaΔpPermissible = 66000 Pa = 660 mbar (residual head at minimum flow

rate)Δp = ΔpPipe circuit + ΔpSupply line = 5900 Pa + 1760 Pa = 7670 Pa

≈ 77 mbar

Result:Δp = ΔpPipe circuit + ΔpSupply line does not exceed the valuefor ΔpPermissible, so the intended geothermal collector can be operatedwith a heat pump with 5.9 kW rated heating output.

On smaller plots, geothermal probes are an alternative to geothermalcollectors when retrofitting existing buildings. In the following we con-sider the double U-shaped tubular probe.One version would be two double U-shaped tubular loops made fromplastic in one borehole. All cavities between the pipes and the groundare filled with a highly conductive material (bentonite, for example).

NotePrior to applying any thermal load to the geothermal probe, we rec-ommend allowing the backfill material to set for 1 to 2 months. Thisimproves the long-term stability of the geothermal probe and reducesthe risk of frost damage (formation of cracks).

We recommend the following spacing between 2 geothermal probes:■ Up to 50 m deep: min. 5 m■ Up to 100 m deep: min. 6 m

The geothermal probes are installed either by drilling or by ramming,subject to their respective design. For these kinds of systems, localwater authorities may have to be notified or a permit to be obtained.Further information can be obtained from the geothermal probe man-ufacturer (see "Manufacturer's addresses" in the appendix).

Rough sizingThe basis for sizing is the cooling capacity ²K of the heat pump atoperating point B0/W35.Required probe length l = ²K/³E (³E = average extraction rate subjectto ground conditions).The detailed sizing depends on the ground structure and the water-carrying ground strata, and can only be determined following a localinspection by the drilling contractor.

NoteThe reduction of the number of drilled holes in favour of probe depthincreases the pressure drop to be overcome and the required pumprate.

Information regarding dual mode parallel and mono energeticoperationIn case of dual mode parallel and mono energetic operation, considerthe higher heat source load (see "Sizing"). As a guide, a geothermalprobe system should not exceed an annual extraction rate of100 kWh/m ∙ p.a.

The heat pump with a heating output of 5.9 kW (incl. supplement forpower-OFF periods, excl. DHW heating), and a cooling capacity of²K = 4.7 kW corresponds to the required output.

Sizing the geothermal probe as double U-pipe■ Average extraction rate:

³E = 50 W/m probe length■ ²K = 4.7 kW■ Probe length L = ²K/³E = 4700 W/50 W/m = 94 m ≈ 100 m■ Selected pipe for the probe: PE 32 × 3.0 (2.9) with 0.531 l/m

Required amount of heat transfer medium (VR)■ Take the content of the geothermal probe including all inlet pipes,

plus the volume of fittings and the heat pump into consideration.■ Provide distributors when number of probes used is > 1. Size the

supply line larger than the pipe circuits; we recommendPE 32 to PE 63.

■ Geothermal probe as double-U pipe.Supply line: 10 m (2 × 5 m) with PE 32 × 3.0 (2.9)

VR = 2 × probe length L × 2 × pipeline volume + supply line length× pipeline volume= 2 × 100 m × 2 × 0.531 l/m + 10 m × 0.531 l/m= 217.7 l

R value (pressure drop) for PE 32 × 3.0 (2.9) (see tables "Pressuredrop" for the pipelines):■ At 430 l/h ≈ 44 Pa/m■ At 860 l/h = 176 Pa/m

ΔpDouble-U pipe probe = 44 Pa/m × 2 × 100 m = 8800 PaΔpSupply line = 176 Pa/m × 10 m = 1760 PaΔpPermissible = 66000 Pa = 660 mbar (max. ext. pressure drop,

= 10560 Pa≈ 106 mbar

Result:Δp = ΔpDouble-U pipe probe + ΔpSupply line does not exceed the value forΔpPermissible, so the intended geothermal collector can be operated witha heat pump with 5.9 kW rated heating output.

Water/water heat pumps achieve high performance factors. Ground-water offers an almost constant temperature all year round of 7 to12 °C. Therefore the temperature level of groundwater as a heatsource only needs to be raised a little higher (compared with other heatsources) in order to be utilised for heating purposes.Depending on the design, the heat pump cools the groundwater by upto 5 K, although its consistency remains otherwise unchanged.■ Due to the cost of pumping systems, we recommend that for

detached houses and two-family houses the groundwater is pumpedfrom a maximum depth of approx. 15 m (see the above diagram).For commercial or large scale systems pumping from greater depthscould still be viable.

■ Maintain a distance of at least 5 m between the point of extraction(delivery well) and the point of re-entry (return well). Supply andreturn wells must be located in the line of flow of the groundwater toprevent a "flow short circuit". Construct the return well so that thewater exits below the groundwater level.

■ Due to fluctuating water quality, we generally recommend systemseparation between wells and heat pump (see technical guide "Heatpump principles").

■ The groundwater flow and return lines to/from the heat pump mustbe protected against frost and must slope towards the well.

Calculating the required groundwater volumeThe required groundwater flow rate depends on the heat pump outputand the rate of groundwater cooling.For minimum flow rates, see the heat pump specification (e.g. mini-mum flow rate for Vitocal 300-G, type BW 301.B13 = 3.7 m3/h).

When sizing the primary pumps, please note that higher flow ratesresult in increased internal pressure drop.

Permits for a groundwater/water heat pump systemThis project requires permission from the "local water authority" [checklocal regulations]. Where buildings must be connected to the public water system, theutilisation of the groundwater as a heat source for heat pumps mustbe authorised by your local authority [check local regulations].

Permits can be subject to certain stipulations.

Types BWCFlow rate and pressure drop in the primary circuit are ensured by theintegral circulation pumps under the following condition:The maximum external heat pump pressure drop (see "Specifica-tion") is lower than the total pressure drop of the heat exchangers inthe primary circuit and the pipework.

CoolantIf coolant from an industrial waste heat process is used as a heatsource for a water/water heat pump, please observe the following:■ The water quality must comply with the limits applicable for copper-

soldered or brazed stainless steel plate heat exchangers (see tablein "Principles").

■ If the water quality falls outside these limits, use a stainless steelheat exchanger in the primary circuit (see table on page 169). Sizingis carried out by the manufacturer of the heat exchanger.

■ The available amount of water must satisfy the minimum flow ratesof the primary side of the heat pump (see specification).

■ The maximum flow temperature (water inlet) for water/water heatpumps is 25 °C. With higher cooling water temperatures, low-endcontrollers (e.g. as offered by Landis & Staefa GmbH Siemens Build-ing Technologies) on the primary side of the heat pump limit the max.flow temperature (water inlet) to 25 °C by adding cool return water.

NoteThe utilisation of coolant is also possible in conjunction with a brine/water heat pump. The max. flow temperature must then be limitedas for the water/water heat pump to 25 °C.

12.10 Central heating/central cooling

Heating circuit

Minimum flow rateHeat pumps require a minimum heating water flow rate (see specifi-cation), which must be maintained. To ensure the minimum flow rate,install an overflow valve or low loss header in systems without a heat-ing water buffer cylinder. When utilising an overflow valve, the controlunit must be set to "constant pressure " for HE circulation pumps.

Low loss headerWhen using a low loss header, it must be ensured that the flow rateon the heating circuit side is greater than the flow rate on the secondaryside of the heat pump.To prevent a fault shutdown, the minimum volume of the low lossheader must be 3 litres per kW rated heating output.The heat pump control unit treats a low loss header in the same wayas a small heating water buffer cylinder. Therefore, configure the lowloss header by means of the control unit settings as a heating waterbuffer cylinder.

NoteAn additional circulation pump is then required.

Systems with large water volumesSystems with large water volumes (e.g. underfloor heating systems)can operate without a heating water buffer cylinder. In these heatingsystems, install an overflow valve at the heating circuit distributor ofthe underfloor heating system that is furthest away from the heat pump.This guarantees the minimum flow rate, even in sealed heating cir-cuits.In conjunction with an underfloor heating system, install a temperaturecontroller as maximum temperature limiter (accessory, part no.7151 728 or 7151 729).

Systems without heating water buffer cylinderTo safeguard the minimum heating water flow rate (see specification),never install a mixer in the heating circuit.

Heating circuit and heat distributionDifferent heating water flow temperatures are required depending onthe heating system design.Heat pumps reach a maximum flow temperature of 65 °C.To enable the mono mode operation of the heat pump, install a lowtemperature heating system with a heating water flow temperature of≤ 60 °C.

The lower the selected maximum heating water flow temperature, thehigher the seasonal performance factor of the heat pump.

NoteFor cooling mode in the following cases, a room temperature sensormust be installed and enabled:■ Weather-compensated cooling mode with room influence■ Room temperature-dependent cooling mode■ "Active cooling"A room temperature sensor must always be installed for a separatecooling circuit.

Weather-compensated cooling modeIn weather-compensated cooling mode, the set flow temperature iscalculated from the relevant set room temperature and the currentoutside temperature (long-term average) according to the coolingcurve. Its level and slope are adjustable.

Room temperature-dependent cooling modeThe set flow temperature is calculated from the differential of the setand actual room temperature.

12.11 Systems with heating water buffer cylinder

Heating water buffer cylinder operated in parallel

Systems with small water volumesFor systems with small water volumes (e.g. heating systems with radi-ators), use a heating water buffer cylinder to prevent excessive heatpump cycling (starting/stopping).

Benefits of a heating water buffer cylinder:■ Bridging power-OFF periods:

At peak times, heat pumps may be switched off by your local powersupply utility, subject to your electricity tariff. A heating water buffercylinder supplies the heating circuits even during this power-OFFperiod.

■ Constant flow rate through the heat pump:Heating water buffer cylinders provide hydraulic separation of theflow in the secondary and heating circuits. For example, if the heatingcircuit flow rate is reduced via thermostatic valves, the flow rate inthe secondary circuit remains constant.

■ Longer heat pump operating times

Because of the increased water volume of the heat source and the factthat it may have a separate shut-off facility, an additional (or larger)expansion vessel should be provided.

NoteThe flow rate of the secondary pump should be greater than that of theheating circuit pumps.

The heat pump is protected in accordance with EN 12828.

VHP = QWP · (20 to 25 litres)QWP = Absolute rated heat pump heating outputVHP = Heating water buffer cylinder volume in litres

Heating water buffer cylinder for optimised runtimes

NoteWith two-stage heat pumps and heat pump cascades, the volume ofthe heating water buffer cylinder can be sized for runtime optimisationto match the heat pump with the highest rated heating output.

Heating water buffer cylinder for bridging periods when the supply is blockedThese versions are offered for heat distribution systems without addi-tional cylinder mass (e.g. radiators, hot water air heaters).Storing 100 % of heating energy for the duration of the power-OFFperiods is feasible, but not recommended, otherwise the cylinder vol-ume required would be too great.

12.12 Water quality and heat transfer medium

DHWThe appliances can be used with potable water up to 20 °dH(3.58 mol/m3). In case of higher hardness levels, a softening systemfor potable water is required on site to protect the integral plate heatexchanger.

Heating water

Unsuitable fill and top-up water increases the level of deposits andcorrosion. This can lead to system damage.Observe VDI 2035 regarding quality and amount of heating water,including fill and top-up water.

■ Flush the heating system thoroughly before filling.■ Only fill with water of potable quality.■ Soften fill water with a water hardness above 16.8 °dH (3.0 mol/m3),

e.g. with the small softening system for heating water (see theVitoset pricelist).

Heat transfer medium, solar circuit (not for Vitocal 222-G, 333-G)■ Fill the solar circuit only with Tyfocor LS heat transfer medium (frost

protection down to −28 °C). Never dilute the heat transfer mediumwith water.

■ Provide an expansion vessel for the solar circuit, sized in accordancewith the details on page 187.

■ Never use zinc-plated/galvanised pipes or components for the solarcircuit.

Heat transfer medium, primary circuit (brine circuit)■ Fill the primary circuit exclusively with Tyfocor heat transfer medium

(frost protection down to −19 °C). Never dilute the heat transfermedium with water.

■ Provide an expansion vessel for the primary circuit, sized in accord-ance with the details on page 187.

■ Never use zinc-plated/galvanised pipes for the primary circuit.

12.13 DHW heating

Function description regarding DHW heating

Compared to central heating, DHW heating makes fundamentally dif-ferent demands, as almost identical amounts of heat must be providedall the year round at the same temperature level.In the delivered condition, DHW heating by the heat pump takes priorityover the heating circuits.The heat pump control unit switches the DHW circulation pump OFFduring cylinder heating to prevent cylinder heating from being impairedor extended.

The max. cylinder storage temperature is limited subject to the heatpump used and the individual system configuration. Storage temper-atures above this limit are only possible with the assistance of a boos-ter heater.

Booster heaters suitable for DHW reheating:■ External heat generator■ Instantaneous heating water heater (accessory)■ Immersion heater EHE (accessory)

NoteOnly use the EHE immersion heater with soft to medium hard waterup to 14 °dH (average hardness level, up to 2.5 mol/m3).

The integral load manager in the heat pump control unit decides whichheat sources to use for DHW heating. Generally the external heatsource has priority over the electric heaters.

If one of the following criteria is met, the booster heaters begin cylinderheating:■ Cylinder temperature is below 3 °C (frost protection).■ Heat pump does not provide any heating output and actual temper-

ature has fallen below set temperature at the top cylinder tempera-ture sensor.

NoteThe immersion heater in the DHW cylinder and the external heatsource stop as soon as the set value at the top temperature sensor isreached, minus a hysteresis of 1 K.

When selecting the DHW cylinder ensure that its indirect coil surfacearea is large enough for the purpose.

DHW heating should ideally take place during the night after 22:00 h.This has the following advantages:■ The heat pump heating output is available for central heating during

the daytime.■ Better utilisation of economy (night) tariffs (if offered by the power

supply utility).■ DHW cylinder heating and simultaneous drawing can be avoided.

When using an external heat exchanger, the system may not alwaysachieve the required draw-off temperatures because of the systemdesign.

Connection on the DHW side (connection to DIN 1988)For the DHW connection, observe DIN 1988 and DIN 4753 (c: SVGW regulations).

Safety valveProtect the DHW cylinder with a safety valve against unduly high pres-sure.

Recommendation: Install the safety valve higher than the top edge ofthe cylinder. This protects the valve against contamination, scaling andhigh temperatures. The DHW cylinder will also not need to be drainedwhen working on the safety valve.

DHW cylinder with external heat exchanger (cylinder loading system) and heating lance

During cylinder loading (no draw-off) in the cylinder loading system,cold water is drawn from the bottom of the DHW cylinder by the cylinderloading pump, heated in the heat exchanger and returned to the cyl-inder via the heating lance built into the flange.The generously sized outlet apertures in the immersion heating lanceresult in low flow velocities, which in turn provide a clean temperaturestratification inside the DHW cylinder.

DHW booster heating is possible if an additional immersion heater isinstalled (on site).

12.14 Cooling mode

Types and configuration

Subject to system version the following cooling functions are possible:■ "Natural cooling" (as option with or without mixer)

– The compressor is shut down and heat exchange occurs directlywith the primary circuit.

■ "Active cooling"– The heat pump is used as a refrigeration unit, meaning a higher

cooling capacity is possible than with natural cooling.– This function is only possible outside a power-OFF period, and

must be enabled separately by the system user.

Even if active cooling is selected and enabled, the control unit will ini-tially start the natural cooling function. If the set room temperaturecannot be achieved with this function for a prolonged period, the com-pressor starts.A mixer can only be used with natural cooling, and particularly in cool-ing mode on underfloor heating circuits, it keeps the flow temperatureabove the dew point. To ensure the transfer of the high cooling outputin active cooling at all times, no mixer is provided.

Cooling function "Natural cooling"

Function description

With natural cooling, the heat pump control unit regulates the followingfunctions:■ Switching all necessary circulation pumps, diverter valves and mix-

ers■ Recording all essential temperatures■ Dew point monitoring

The control unit enables the natural cooling function if the outside tem-perature exceeds the cooling limit (adjustable). Control operated inweather-compensated mode when cooling via heating circuit (under-floor heating circuit). When a separate cooling circuit is used, e.g. afan convector, then the control is room temperature-dependent.DHW heating by the heat pump is possible during the cooling opera-tion.

Note■ For cooling operation via a separate cooling circuit, a room temper-

ature sensor must be installed and enabled.■ For cooling operation via a separate cooling circuit or heating circuit

without mixer, use a contact temperature sensor to capture the flowtemperature.

NC-Box■ The installation room must be dry and free from the risk of frost.■ Vitocal 200-G/300-G: Install the NC-Box inside the installation room

above the heat pump and connect with the corrugated pipes sup-plied.

■ Compact heat pumps: Install the NC-Box near the compact heatpump and use on-site pipes for the hydraulic connection.

■ Carry out the diffusion-proof thermal insulation of all brine and coldwater lines in accordance with standard practice to prevent conden-sation.

■ Power supply (1/N/PE, 230 V/50 Hz) is required.Recommendation: Utilise the heat pump power supply from an on-site power distribution board.

■ If the NC-Box is used with a separate cooling circuit (exclusivelyused for cooling), protect that circuit via an additional expansionvessel and safety valve.

■ Use only Teflon and EPDM seals for the connections on the NC-Box.

Natural cooling with the NC-BoxSubject to the probe/collector system and the temperatures underground, the NC-Box can transfer a cooling capacity of up to 5 kW.For cooling, it is possible to connect either a heating/cooling circuit,e.g. underfloor heating circuit or a separate cooling circuit, e.g. a fanconvector.

The NC-Box is supplied with all necessary components:■ Circulation pumps■ Diverter valves■ Mixer■ Sensors■ KM BUS interface for heat pump control unit

The heat that is extracted from the heating/cooling circuit is transferredto the ground by the heat exchanger in the NC-Box. This heatexchanger is connected in series and enables a system separationbetween the primary and the heating circuit.

NoteThermally insulate all lines on site with vapour diffusion-proof mate-rial.

Arrangement of the NC-Box adjacent to the heat pump■ For compact heat pumps Vitocal 222-G, 242-G, 333-G type BWT,

343-G■ For Vitocal 200-G, 300-G, if there is insufficient space above the heat

pump to carry out the installation.■ Hydraulic connection with on-site pipework.

Cooling with an underfloor heating systemThe underfloor heating system can be used for heating and for coolingbuildings and rooms.Underfloor heating systems are hydraulically connected to the brinecircuit via a cooling heat exchanger. A mixer is required to match thecooling load of the room to the outside temperature. Similar to a heat-ing curve, the cooling capacity can be matched exactly to the coolingload via a cooling curve and the cooling circuit mixer that is regulatedby the heat pump control unit.Surface temperature limits must be maintained to observe comfort cri-teria and to prevent condensation. The surface temperature of theunderfloor heating system in cooling operation must not fall below20 °C.Install a natural cooling contact humidistat (for capturing the dew point)in the underfloor heating system flow to prevent condensation formingon the floor surface. This safely prevents the formation of condensate,even if weather conditions change quite rapidly (e.g.during a thunder-storm).

The underfloor heating system should be sized in accordance with aflow/return temperature pair of approx. 14/18 °C.The following table can assist in estimating the possible coolingcapacity of an underfloor heating system.

In principle, the following applies:The minimum flow temperature for cooling with an underfloor heatingsystem and the minimum surface temperature are subject to the pre-vailing ambient conditions inside the room (air temperature and rela-tive humidity). These must therefore also be taken into considerationduring the design phase.

Cooling with fan convectors Vitoclima 200-C (accessory)■ Cooling mode possible either via separate cooling circuit or via a

heating/cooling circuit.■ Select an installation location where the heat pump can be easily

connected.■ Bear in mind that the condensate drain must be connected to the

domestic drain network or that the condensate must be routed out-doors.

■ Power supply (1/N/PE 230 V/50 Hz) required.■ When creating wall ducts, consider supports, lintels and sealing ele-

ments (e.g. vapour barriers).■ Only fit appliances to solid level walls.■ Never install appliances near heat sources or places subject to direct

solar irradiation.

■ Install appliances only in locations with good air circulation.■ Ensure easy accessibility for service.

Output matchingThe output of fan convectors can be modified. By changing the termi-nal connections, 3 of the available 5 speeds can be assigned to the 3-stage speed selector of the fan convectors.The heating outputs and cooling capacities available at the respectivespeeds are shown in the following table.

Cooling function "Active cooling"

Function descriptionBrine/water and water/water heat pumps can, during spring, summeror autumn, utilise the temperature level of what is used as a heatsource in winter as a heat sink, i.e. to cool the building with naturalcooling.At the same time, active cooling can be achieved by starting the com-pressor and reversing the functions of the primary and secondarysides.The heat generated is dissipated via the primary source (or a con-sumer).

The AC-Box always responds initially to a cooling demand with thenatural cooling function.If the cooling capacity is no longer sufficient, the system changes overto the active cooling function.The heat pump starts to operate and the cold side (primary circuit) andhot side (secondary circuit) are changed over via the AC-Box.The heat generated is made available to the connected consumers(e.g. DHW cylinder). Excess heat is dissipated into the ground or wellsystem.

GB

To prevent the geothermal collectors or probes being overloaded (riskof drying out), the temperature and its spread are permanently moni-tored by the heat pump control unit. If overloading occurs, the systemautomatically changes over to natural cooling.All required circulation pumps, valves and mixers inside the AC-Boxare regulated by the heat pump control unit. A contact humidistat must be fitted to a free pipe piece outside the AC-Box.

Note■ For cooling operation via a separate cooling circuit, a room temper-

ature sensor must be installed and enabled.■ A cascade of several AC-Boxes is not possible. The maximum cool-

ing capacity is limited by the cooling capacity of the connected heatpump, and by the sizing of the primary source.

We recommend positioning the AC-Box to the left of the heat pump.This enables access to the internal components from the front or theleft. The connection set (see chapter "Installation accessories") isdesigned for this method of connection.

NoteIf the appliance is installed together with a heat pump (type BW) forwhich no connection set is available, the connection must be made onsite, because additional pumps need to be installed.

SizingThe maximum cooling capacity of the AC-Box is limited by the heatpump.

Example:For the Vitocal 300-G, type BW 301.B06, the maximum system coolingcapacity is 4.9 kW.

Conditions:■ The installed primary source has been sized for the output.■ The installed primary source can transfer the generated heat.

NoteFor operation with the AC-Box, inform the engineer or drilling contrac-tor about the sizing. The primary source must be sized accordinglylarger.

Hydraulic connectionWe recommend connecting the AC-Box to the heat pump with theconnection set (see chapter "Installation accessories"). The connec-tion set is already thermally insulated.

12.16 Connection of a solar thermal system (for Vitocal 200-G, 300-G, 350-G, 242-G,343-G)Together with a solar controller, a solar thermal system can be utilisedfor DHW heating, central heating backup and swimming pool heating.The heat-up priority can be selected individually at the heat pump con-trol unit.The heat pump control unit enables certain values to be checked.When there is a high level of insolation, all heat consumers can beheated to a higher set value, thereby raising the solar coverage. Allsolar temperatures and set values can be scanned and adjusted viathe control unit.To prevent thermal shocks inside the solar circuit, the operation of thesolar thermal system will be interrupted at collector temperatures> 120 °C (collector protection).

Solar DHW heatingThe solar circuit pump starts and the DHW cylinder is heated up, if thetemperature differential between the collector temperature sensor andthe cylinder temperature sensor (in the solar return) is greater than thestart temperature differential set at the solar control unit.The heat pump will be prevented from heating the cylinder if the tem-perature at the cylinder temperature sensor (in the DHW cylinder, top)exceeds the set value selected at the heat pump control unit.The solar thermal system heats the cylinder to the set value selectedat the solar control unit.

NoteFor the aperture area that can be connected, see the "Vitosol" techni-cal guide.

Solar central heating backupThe solar circuit pump and the circulation pump for cylinder heatingstart, meaning the heating water buffer cylinder is heated up, if thetemperature differential between the collector temperature sensor andthe cylinder temperature sensor (solar) is greater than the start tem-perature differential selected at the heat pump control unit.

Heating stops when the temperature differential between the collectortemperature sensor and the cylinder temperature sensor (solar) is lessthan half the hysteresis (standard: 6 K) or if the actual temperaturecaptured by the lower cylinder temperature sensor corresponds to theselected set temperature.See also the "Vitosol" technical guide.

According to the [German] Energy Saving Ordinance, the temperaturein each room must be individually controlled, e.g. by means of ther-mostatic valves.

Time switch

Digital time switch (integrated into the programming unit)■ Individual day and seven-day program■ Automatic summer/wintertime changeover■ Automatic function for DHW heating and DHW circulation pump■ Standard switching times are preset at the factory, e.g. for central

heating, DHW heating, charging a heating water buffer cylinder andswitching the DHW circulation pump.

■ Time program is individually adjustable; up to 8 time phases per dayShortest switching interval: 10 minPower reserve: 14 days

Setting the operating programsFrost protection monitoring for the system components is enabled inall operating programs (see frost protection function).You can select the following operating programs via the menu:■ For heating/cooling circuits:

"Heating and DHW" or "heating, cooling and DHW"■ For a separate cooling circuit:

"Cooling"■ "Only DHW"; separate settings for each heating circuit

NoteIf the heat pump only needs to be on for DHW heating (e.g. in thesummer), the operating program "Only DHW" must be selected forall heating circuits.

■ "Standby mode"Frost protection only

The operating programs can also be switched over externally, e.g. byVitocom 100.

Frost protection function■ If the outside temperature falls below +1 °C, the frost protection

function is switched on.With active frost protection, the heating circuit pump will be switchedon and the flow temperature in the secondary circuit will be main-tained at a lower temperature of approx. 20 °C.The DHW cylinder will be heated to approx. 20 °C.

■ If the outside temperature exceeds +3 °C, the frost protection func-tion is switched off.

Heating and cooling curve settings (slope and level)

The Vitotronic 200 regulates the flow temperatures for the heating/cooling circuits in weather-compensated mode:■ System flow temperature or flow temperature of heating circuit with-

out mixer A1■ Flow temperature, heating circuit with mixer M2:

Depending on the heat pump, the mixer motor is controlled eitherdirectly by the control unit or via the KM BUS.

■ Flow temperature, heating circuit with mixer M3:Not available with every heat pump; mixer motor switching via theKM BUS.

■ Flow temperature for cooling via heating circuit; the regulation of theseparate cooling circuit is room temperature-dependent.

The flow temperature required to reach a specific room temperaturedepends on the heating system and the thermal insulation of the build-ing to be heated or cooled.Adjusting the heating or cooling curves matches the flow temperatureto these conditions.

■ Heating curves:The flow temperature of the secondary circuit is restricted at theupper end of the scale by the temperature limiter and the maximumtemperature set at the heat pump control unit.
