1 Introduction The HRP22 is specifically designed for the control, optimisation, and monitoring of heating systems. In addition to its default programs it can be configured to control a wide range of applications. It has unique user configurable logic can involve local and network parameters to develop the required strategy. The controller can be configured to interface with other HRP/LRP devices on a network as required. The HRP can also be connected to a wide range of BMS systems and can also be interfaced via a local internet/intranet connection with the use of supplementary devices. The HRP/LRP solution is comprehensive enough to replace and simplify the operation of most BMS Applications. Each HRP22 can control up to two zones of VT heating with either 0-10v or 3-point valve actuation in addition to boiler/calorifier plant and DHWS control. Each has 6 Digital outputs and 5 Digital Inputs (3 on HRP22-M), 6 Temperature Inputs, and 2 0-10v Signals that can be used to accommodate many varied applications. Parameters can be shared between controllers and each controller can provide full user access to any other controller on the network. The HRP22 M also has an additional M-Bus that enables the connection of 4 Utility Meters to the HRP where readings and recordings can be made and displayed. Again the meter data can be interfaced with the control strategy or reported to a point of contact be it a BMS or Local Alarm.

• Bus and modem can be directly connected. • Joint control of heat exchangers and the compensated circuit. • One-knob operation with a graphically illuminated display for the input and

query of all DDC data on the Bus • Optimised Plant Start/Stop • Room Correction • Temperature Limits for plant protection and condensation control • Energy Saving Routines • Multiple Boiler Control • Domestic hot water control • DHWS Circulation Pump control • Operating Hours Counter • Modem, GSM Modem, or WWW connectivity options • Automated Protection against Pump Blockage. • Three Independent Time Schedules • Holiday Schedule • Special event (Single Shot) Schedules • Trend value and display of important plant values • In built frost routines – minimum flow, outside, and space temperatures

This controller is ideal for applications where heating systems involve boilers or the control of non-storage heat exchangers as a primary source in addition to the main heating circuits.


The controller also incorporates Standard Programs for Pump Auto changeover options, Legionella protection for the DHWS Storage Calorifier, Automated Summer/Winter Time Changeover, Leap Year, Full Configuration Back Up and restore options, and a huge library of schemes in our fully documented library. The user is guided through the settings via a plaintext menu system. Reading and writing of the data takes place in 4 priority levels accessed through individual codes. Eight HRP/LRP controllers can be administrated on each of the employed HRP LRP Bus Systems, each LAN can operate over a distance of 1000 m. Full remote control of one HRP/LRP is possible from any other HRP/LRP connected on the same LAN. Important plant values and information can also be shared to facilitate plant integration directly between controllers without the need of a front end. For wide area networks, the separated plants can utilise data transmission to the user via modem over the world wide web. This can take place with direct connection of the modem to the Webbiter interface.

• Programmable functions with markers, timers and time programs • 6 analogue inputs for active measuring element KP10 • 1 analogue input 0..10 V or 0-10k Ohm • 5 digital inputs • 2 analogue outputs 0..10 V • 6 digital outputs • Plastic housing fire-resistant, for control panel mounting, • Mains 230 V AC ± 10 % 50..60 H

2.6 Connection of the bus system A maximum of 16 HRP or LRP can be connected to the bus system.

2.6.1 LAN WIRING PRECAUTIONS • The maximum length of the bus systems may not exceed 1000 m. • The connection of the Bus System is with two pair twisted screened insulated

wires. • Do not run adjacent too or fix to power cables during installation. • Termination resistors of 180 Ohm must be attached at both ends of the Bus

Systems between the connection terminals Bus+ and Bus - (this LAN terminating resistor is supplied with each controller)

2.7 Setting the language of the controller • Perform a cold start of the controller by holding both the SET and ESC keys

whilst applying power to the controller. • The first menu presented will be the language options for the device • The language is set in parameter 2960 “Language”. This is found in

“Configuration” “Language”

2.8 Addressing the HRP/LRP bus systems The network address of the HRP/LRP is set on the device itself in software. If two devices within the HRP/LRP bus systems have the same address, then a system error "duplicate address" is sent. The default address is 16 for each controller

• The address is set in parameter 2943 “Bus Address”. • This is found in “Configuration” – “HRP Bus”


2.9 Connection possibilities to the serial interface The HRP and the LRP each posses two connection possibilities for communication on the serial interface RS232. In the following table, all communication possibilities are listed. Interfaces function RS232 reverse side socket RS232 front side diagnosis

jack *1) Data backup and restoration

Firmware Update Modem/GSM Modem x ModBus/Jbus x *1) The RS232 diagnosis jack on the front side of the HRP and of the LRP has priority in reference to the RS232 connection on the reverse side. If this diagnosis jack is in use, then no RS232 communication can take place on the reverse side of the device (socket). Communication on a telephone selection modem is carried out exclusively on the RS232 connection on the reverse side of the device. Note: If the distance between the PC and the first controller is greater than 20m additional line drivers are required due to the RS232 Protocol. Please contact your local sales agent or call +44 (0) 870 2080100 for assistance as a wide range of solutions are available.


2.10 HRP/LRP Tools: Data backup, Data restoration Controller programs can be configured, saved and downloaded to controllers. User configured applications can be copied and saved to multiple controllers using the LRP/HRP Tool utilities. The tools enable full controller configuration without the need of a connected controller. Controller type files specific to the model are created by the application for immediate download into the controllers when used in conjunction with the appropriate connection lead DDC3000.001.

All menu options can be configured along with menus, set values, parameter text and logic.

4 HRP Functionality Checklist ..................................................................................................95


3.1 Main Menu The Main Menu is typically a weather-compensated flow temperature control loop however it can be a fixed set point control loop when required. The HRP controller will calculate the required flow set point based on the influence of outside air temperature and space temperature. The compensated flow set point follows the actual outdoor ambient temperature (TA) normally connected to input b1. There is however an option in the controller to use a delayed sensor reading.

The current compensated flow set point can be displayed using the parameter “5151 Feed.setp act”, this can be found in the Main Menu. In normal control and depending upon the application/specification, minimum and maximum values can be set for the VT flow temperature using the menu options Feed Min, Feed Max.


3.1.1 Setting up the second ratio The HRP heating curve can have two ratios, however the default settings only configure one. In the example below, the first change point is fixed for an outdoor temperature of 15 °C. If the selected outdoor temperature is less than the value set in the parameter “5066 Htg crv2 start” (default 5 °C), a change to Heating curve EF2 takes place. Using the figure stored in the parameter 5065, ratio 2 can be set. The required outside temperature required to initiate the change over from ratio1 to ratio 2 can be configured between +10.0 °C and -10.0 °C. If the outdoor temperature rises again to a value larger than that set for Heating curve EF2on then the Heating curve EF is valid again. In day operation the flow temperature is controlled according to the calculated flow set point (5151). The calculated flow set point in Basic Program 1 can also be influenced by the room temperature set point according to the following formulae: Without room influence enabled Current Flow Set Point = (((20 - Outside Temp) * EF) + KH)) + ((Room Set Point Day – 18) *6 ) With room influence enabled Current Flow Set Point = (((20 - Outside Temp) * EF) + KH)) + ((Room Set Point Day – Current space temp) *room influence ratio) At night, the above apply but the Night Space set points and 5167 Night Setback setting apply. In holiday mode, if applicable a temperature-lowering room correction can go into operation:

if a room sensor exists, the temperature is monitored in case it falls below the room set point holiday value. If this occurs, the room temperature is controlled until room set point holiday is exceeded by more than 1’C. In Off mode only the pump blockage protection and frost protection are active. In Holidays operation the circulation pump of the closed-loop control is turned off (but frost protection and pump blockage protection are still active). Additional functions: Several additional functions can influence the closed-loop control function in the Basic Menu. Pump blockage protection - The heating circulation pump of the Basic Program is switched on daily at 12 noon for 2 minutes (automatic pump blockage protection has no configuration parameters). All the controller menus that drive pumps will be exercised at the same time. Main Menu Frost protection - The activated frost protection function ensures that the heating circulation pump does not switch off for an outdoor temperature < 3 °C even outside of normal operation. The objective it to prevent the heating plant from freezing. The heating circulation pump is only shut off when the outdoor temperature rises again to a value > 6 °C. The frost protection function can be switched on or off with the parameter frost protection Yes/No. Due to the requirements of the UK Market we usually select NO for this feature and configure a Limit Value to provide frost protection. The limit value is inverted and linked into the remote control menu for the associated control loop. Control to Outside Temp/Delayed Outside Temp/Fixed value - The delayed outdoor temperature is calculated in the Basic Program Heating. By setting the parameter control according to “Outside", the heating regulation is not controlled according to the delayed outdoor temperature "TAVZ" but according to the actual outdoor ambient temperature "TA". The calculation of the delayed outdoor temperature takes place at a fixed delay of 6 hours to accommodate fluctuations and aid a more stable temperature control. When control is set according to "fixed value", the Basic Menu regulates the temperature according to a fixed value set point. Switching to fixed value set point Using parameter 5152 control according to you can stipulate whether the HRP Main Menu should control according to TA, TA Delayed or according to a fixed value. Please note that when fixed values are used the control loop has a sampling interval of 5s and is NOT suited for rapid control system. If fixed value control is enabled, the following statements apply: If the allocated utilisation period program is active:

- Room set point day acts as set point for the day operation (basic setting: 20 °C)


If the allocated utilisation period program is inactive: - The room set point night acts as set point for the night operation (basic

setting: 15 °C, range of 5 °C to 120 °C)

If the Holiday program takes effect: (parameter 5075 – holiday prog allowed = yes - The room set point holiday acts as set point for the holiday operation

(basic setting: 12 °C, range of 5 °C to 120 °C)

If the Main Menu is set to fixed value, the following HRP menus have no effect: - Economy function - Room correction - Optimisation DHW Control (domestic hot water) priority function – The HRP has an extended DHW priority function. When there is a DHW request, the parameter DHW priority (setting "no", valve on, pump on) is used to stipulate whether the VT circulation pump should be switched off or the heating control valve of the Basic Menu is to be closed. The parameter ext.DHW-boiler on (boiler meaning Calorifier in this example) can be used to stipulate which digital signal within the HRP/LRP bus system sets the DHW-boiler priority function. In the basic setting this parameter is deleted, which means that the DHW request of the same device is being used. Other digital sources (such as external time schedules or timers) can also trigger the priority function by means of source parameterisation. Further information on the extended DHW priority function can be found in the description of the DHW Control menu. External heat requests with the parameter 5183 extTfmin - By using the source parameter extTfmin, any analogue sources on the heating requests can be parameterised within the entire HRP bus system. If an analogue parameter in the source extTfmin has been entered and is valid (no "---" display), there is a maximum selection between extTfmin and feed min of the Basic Program. The Basic Program always goes into closed-loop control operation as soon as the value in the source extTfmin is valid (anything other than "---" being displayed). This does not apply when the closed-loop control has been switched to "Off" via Manual/State or BMS Z-influence. ECONOMY: The Parameter 5170 ECONOMY is switched off and on with the parameter ECONOMY Yes/No. If the calculated VT Flow temperature drops so low that only slight heating can be offered to the room, the circulation pump (output i1:Circul.pump) for activated ECONOMY function is switched off. The boiler is switched off as well, as long as it is not switched off by another heating control loop or a boiler request. The output i3 switches to "0" and the calculated flow set point 5151, needed to enable main menu control, is removed. If a higher feed temperature is required, the boiler and circulation pump will switch back on again.


In active ECONOMY function the output I19: Economy is also set to "1". The ECONOMY function distinguishes between floor and radiator heating by means of the heating characteristic slope EF . On and off switch conditions of the function ECONOMY: Boiler Circulation pump EF < 1.0 (floor heating) EF > 1.0 (radiator

heating) Off Flow set < Room setp Flow set < Room setp +

5K On Flow set > Room setp +

2K Flow set > Room setp + 7K

If one of the menus "Room correction" or "Heating optimisation" has been set, the room set point is set there. Otherwise ECONOMY works with an assumed fixed value of Room Set = 20 °C. With the parameter 5151 Feed setp act, the value of the current set point is displayed. Feed min and Feed max have a higher priority than the set points day, night, or holiday; this means that the Set points for the day, night, and holiday operation always have to lie within the range between Feed min and Feed max values. If this is not the case, then Feed min or Feed max applies.

• EF (Ratio) and KH (Origin) have no impact on the fixed value control. • The functions of pump blockage protection, frost protection, manual, and

boiler priority continue to apply. • The function "external heating requests" remains active via the parameter

5183 extTfmin. Using digital contacts switched by SyxthSense products such as the LAP 5 or EZR Modules you can also externally switch to day control, night, or holiday from a remote location such. Pump Overrun The time set in parameter 5182 will keep the VT Pump running post any demand on the heating system. When the overrun has expired the pump will be turned off. To disable the overrun set the time to 0mins. Changes to this parameter will be acknowledged on the next demand of the pump. It is worth noting that the VT pump will initialise into overrun when the power to the controller is applied, this is to provide dissipation for the boiler circuit. The Control Loop The Main Menu is a PI control loop and the PB and IA settings can be modified in parameters 5120 and 5106 respectively.


3.2 Main Menu Operation and Integration with other menus This menu is always set, it is potentially the only optimised loop and its flexibility is quite outstanding. This flexibility means that its parameter list is extensive on first sight however it is important to state here that all are not used on every scheme. Most of the parameters are for information only or are repeated in other menus, do not panic, they all have a sensible and understandable role to play in your scheme should you chose to set them. It is very important to understand how the loop integrates with other controller menus and how the Main Menu option can be manipulated to deliver the desired result.

3.2.1 Menu Influences (In Priority Order) Chimneysweep If this general option is enabled, the main menu is put into a boost override condition. The valve will control to the Feed Max Setpoint and the plant (boilers/pumps) will be enabled. If Chimneysweep is active, the manual LED will be illuminated and the Chimneysweep man will be displayed. 5170 Economy (i19) If the economy mode is enabled within the Main Menu this has the capability to disable the Main Menu if the calculated set point is within 3’C of the actual flow temperature. If the Economy mode is active the Manual/Status Screen will display “Economy”. This feature can cause some operator confusion and this should be explained carefully during any handover. The feature is a good way to reduce operational costs but the expectation of heating being on at all times can be a burden post installation if not communicated to the right persons on site. ECO Standby (i8) This is a general option within the Menus list. If the average outside air temperature exceeds the set point within this menu for the period of days set then the Main Menu will be disabled. If this mode is active and the previous influences are not active then the controller will display “Standby” in the Manual/Status Screen. Remote Control This is a general menu option. The main menu can be forced into Day mode/Night/Holiday or Off by programming the appropriate references. This menu is key providing interlocks or panel overrides for Day Extension, Summer, Holiday etc. Override to day is used for return frost control as well as time extensions. This has the highest priority within the remote control menu of option. If the optimiser is correctly enabled the Night flag can be used to put the controller into Frost protection. If the optimiser is not being used then the night flag will put the controller into Night Set Back. Override to Holiday will disable the Main Menu and HWS loop unless this has been set not to do so. (see the HWS Control Menu). The Main menu will control the space temperature to the low limit of the Holiday Set Point found in the main menu. Control Off can be used to turn the plant off in the case of an override or safety interlock. The pump will overrun via i1 but the control off flag could be used to disable the pump as required All overrides can take up to a minute to take effect so this must be factored in critical applications or demonstrations; this is to co-ordinate the optimiser correctly.


Vacation Program If 5075 holiday mode is enabled within the Main Menu this has the capability to permit the Main to follow any programmed vacation periods. If no other overrides are active, the controller will display “Holiday” in the Manual/Status screen Optimise (i6/i7/i10) If the optimiser is active the main menu will follow the dictated flag conditions to achieve the required space conditions. Optimiser Sequence of Stages

i1 Heating Circuit 1 Pump On i3 Boiler Start On i4 Day On i5 Night On i6 Optimiser: Heating Up/Run Down Oni7 Regulator Heat (Boost) On i10 Interim Heating On

3.2.2 Key Points

1. The main menu can be optimised, however if the Optimiser is not enabled or the room sensor is not configured/connected then the optimiser will not influence the Main Menu. ( i.e. i6, i7, i10 will not operate)

2. If there is no optimisation then the heating will move from Day to Night at the end of occupancy, the pump will remain active unless in Economy mode.

3. The change from Day to Night will drop the calculated flow set point by the amount configured in Main Menu/ 5167 Night Set Back

4. The calculated flow set point is not based only on ratio, origin and outside air temperature. The following also apply:

Room Influence (adjustable ratio) Room Set point Day (fixed ratio 6:1 at an origin at 18’C) Remote Adjuster

Room Temperature

Setp Day

Setp Night

i1 i3

i4 or Remote Control

i7/i6

i5 i10 i6


5. The customer has the ability to directly increase space temperature by changing the Day Set point.

6. If no sensor is connected to the room input, it is recommended to leave the Day Setp (Parameter 5180) at 18’C

7. The menu option “Limitation” should be disabled if a standard macro is being used as this is generally not used in the UK.

3.2.3 Parameter Explanations for Engineers 5152 Control After

Option 1: Toutside The Main menu uses the current outside air temp to calculate the Variable VT Flow Temperature

Option 2:Tout delay The Main menu uses the delayed outside air temp to calculate the Variable VT Flow Temperature. This value is the outside air temp 6 hours prior to the current reading.

Option 3:Fixed Setp The Main menu uses the Room Setp Day (5180) during the Time on period and Room Setp Night (5181) during a time off period. The fixed set point option can be used for many types of application. Be sure to disable the loop if it is not needed out of hours by using “Remote Control Off”.

5171 Frost Protection This should be disabled in a standard Macro and a limit value should be used unless there are no limit values available. The Frost setting will run the VT Pump when the outside air temp falls to 3’C and will turn off the Pumps when the outside air temp rises to 6’C 5172 Design Parameter 5172 in the main menu can be used on underfloor heating and radiator circuits that operate 24hrs with a night setback facility. The default setting of –12’C is the outside temperature that the night set back settings will not be able to sustain the building temperature due to heat losses. When this temperature is met the HRP will automatically switch to the Day settings no matter the current time of day. 2766 AT Day Earlier This parameter is used in under floor heating schemes that are not optimised. It works in combination with parameter 2767 to provide a form of advance pre-heat based on the outside air temp. 2766 is the outside air temp base setting, should the time schedule be off and the outside air temperature be below the setting 2766 then the difference is multiplied with the factor in 2767 to give a time in minutes that the controller will switch to the day conditions prior to the schedule turning to normal day time. To indicate this fact the software flag i43 will be turned on. Basic Menu 2 has the same feature but i44 will be turned on to indicate early start.


2768 Pump Cycle Option 1: Continuous (PC Tool Setting 2) Runs the VT at all times there is a demand for heat Option 2: On (PC Tool Setting 1) Runs the VT Pump until the VT Flow temperature matches the calculated VT set point. When the error is zero the pump will be turned off for 5 minutes. After the 5 minute period the pump will be run for 2 minutes. If the VT Flow temperature falls below the calculated flow temp then the pump will continue to run until the error is removed. The cycle continues until the end of heating demand. Option 3: Off (PC Tool Setting 0) Runs the VT Pump until the VT Flow temperature matches the calculated VT set point. When the error is zero the pump will be turned off until the VT Flow temperature falls below the calculated flow temp. This cycle continues until the end of heating demand. 5151 Feed Setp Act The calculated flow setpoint. When the value appears then there is a true demand form the heating loop. If the value ??? is shown then the heating is off and the pump will go into its overrun period. 2840 Limit Test The limit test function permits the controller to raise an alarm if the sensors connected B1 to B6 go outside the default ranges. To disable the alarms simply turn off the related bit by setting it to 0. e.g. 110111 this shows that B3 limit testing is disabled.

3.3 Basic Menu 2 The Basic Menu 2 "Heating" is weather-compensated temperature control loop or a fixed value control loop. The functionality is identical to that of the Main Menu however, the following features do not apply:

• Optimise • Room Influence • Remote Adjust

The HRP controller is able to calculate the required flow set point based on outside air temperature. The control modes and system interactions are as follows:

• The outdoor temperature assignment for Basic Menu 1 should be assigned if there is no separate outdoor sensor available for the 2nd zone

• The Optimised Start/Stop from Menu 1 can be configured to effect Menu 2 if required.

• Room influence is not available as a default option on heating menu 2

3.4 Control Function The menu "Control" in the HRP22 and HRP22-M sets the operation of all digital outputs. The outputs are automatically configured by the Macros where needed by the application selected. If Digital Outputs remain available, additional interlocking, or a complete change to the default programming is required, the following options will enable full configuration of the output logic. The output logic can utilise any digital variable in the controller or HRP/LRP Bus in addition there are Timers, Markers, and other system variables that can be used to develop personalised configurations and applications.

The control is activated as of code level 4 via the menu point "Control". Logic strategy is easily configured. The current status of all digital outputs and flags is displayed in the configuration window as you configure you logic. The current status of both the outputs and the logic driving the output are given. This enables fast trouble shooting thus error free configuration during changes on the controller. The logic can also be engineered using HRP/LRP Tools on a PC. Exactly the same functionality is given to the engineer, as on the controller however the PC Tools does not require a controller to be made available.


Each digital output can use up to four digital sources to enable its operation. These digital sources are configured in the point, i.e. connected to relay outputs or used to enable/disable features of the controller. E.g. Boiler Interlocks, Pump Changeover, Frost control etc. Markers are used to expand the logic complexity. Markers (M), Limit Values (G), Software outputs (i), Timer outputs (T) or contact outputs (K) serve as reference points to be included in the logic strategy. The result of a marker can itself be used to subsequently provide reference for further markers or for directly switching physical outputs. E.g. If more than four inputs are required to be involved in the strategy then Markers can be used to chain the required logic in order to expand the scope. Parameters from any controller connected on the LRP/HRP bus can be referenced if the bus is available. If you are connecting to a variable in the same controller you must select address 0. For example to drive the digital output K6 of controller number 16 from a time schedule you could select: 0.N1 Time Schedule 1 from the same (local) controller number 16 2.N1 Time schedule 1 from controller address number 2 14.N3 Time schedule 3 from controller address number 14 The following example shows how a simple logic strategy can be used to set the state of a Marker: In the above example Marker 1 with be set to a value of 1 when the following occurs: The Main Heating menu requests the Circulation pump to run (0.i1) AND Time Schedule number 1 is On (0.N1) AND Limit level 1 has been exceeded (0.G1) Or The frost stat connected to controller number 2 input k1 returns a logic 0, note this will be seen as a logic 1 because it has been inverted, the • symbol indicates this.

3.4.1 Timers When time is a requirement of the logic there are timers with switch-off delay, switch-on delay or switch-on and switch-off delay. The timers are set in HRS:MINS:SECS and can be set with a time between 00:00:01 to 10:00:00 (1 second to 10 hrs). The timer value counts down when the input variable changes state. Any digital value can be used to trigger the timer. The key below is a useful reference, the dashed lines represent the input state and the solid lines represent the timer state. Timer outputs can be inverted if required, the user is asked this during the configuration Delay Off Delay On Delay On and Off

3.5 Remote Setpoint Characteristics The software menu "Remote Setpoint" can be activated once in the HRP. Function The software menu "Remote Control" addresses an analogue source where a remote set point control is connected or from another scaled analogue value on the network. With the HRP, this menu is used for a set point adjustment; the value generated by the input is not made visible in the form of a displayed set point only its influence can be displayed. The value generated by the input is internally taken into consideration when calculating flow temperatures within the controller algorithms. Special features of the HRP: With the help of the remote control you have the option, for example, of changing the room set point or the feed set point by +/-5K with a set point room module. When the menu "Room correction" is set, a correction of the room set point from -5K .. to +5K (Default Setting) is carried out. The settings of the parameters Start Remote Ctrl. and End Remote Ctrl limit the range of the influence available. With menu "Room correction" enabled the feed set point is corrected by - 5* 2 * EF .. to +5K * 2 * EF under the default settings. The set point correction is valid both in day as well as in night operation. The set point correction is not effective in holiday operation and during reduction (with room sensor and opt.). In connection with the fixed set point control (Setting: control according to fixed set point), the remote control remains ineffective. The menu "Set point controller" has an exclusive effect on the basic menu 1 of the HRP. Parameters Par.No. Parameter Plaintext Lower

3.6 Hours-run meters Characteristics The software menu "Hours-run meter" can be activated twice in the HRP. Function The software menu counts the operating hours ("hours run"). Counting takes place when the digital source parameter Q input is a logical 1. The counting occurs in full hours and is displayed in the parameter Runtime. Begun hours are taken into account in the subsequent count cycle. The hours-run meter can be reset to zero by writing over the parameter Runtime. Par.No. Parameter Plaintext Lower

3.7 Heat quantity meter Characteristics The software menu "Heat quantity" counting can be activated twice in the HRP. Function This software menu is responsible for the counting from heat quantity or pulses (to 20 Hz). In the HRP the following input contacts have fixed assignments for the acquisition of pulses and for power calculation: heat quantity meter 19/1 heat quantity meter 19/2 HRP20/21/23/24 K4 K5 HRP22 K2 K3 A set heat quantity or heat power is assigned to every pulse via the parameter WW Factor. Counting always takes place at the 0/1 edge. The power is determined from the recorded heat quantity per time unit.

Function With the software menu "Min/Max/Mean" you can simultaneously calculate the smallest value, the greatest value, the average, and the difference from up to 4 arbitrary analogue signals. The calculation of the minimum, maximum and means takes place in cycles every minute. The four analogue signals are recorded by configuring the source values/inputs of Q input 1..4 MMM1. The calculated value of the minimum, maximum and means is prepared respectively at the parameters minimum res. MMM1, maximum res. MMM1. mean res. MMM1 and Diff MMM1. These values can be accessed by related configuration of the other HRP/LRP controllers on the HRP/LRP bus system. Par.No. Parameter Plaintext Lower

3.9 Limit values Characteristics The software menu "Limit value" can be activated 8 times in the HRP22. Function With the software menu "Limit value" you can reference any analogue values in the HRP/LRP bus system with regard to value violations. The address of the analogue values to be monitored is configured in the source parameter Q curr.actual value . If the configured points limit value 5741 is exceeded, the parameter result limit val. is set to 1. This value can be configured as a digital source in makers or to generate a message, event, or alarm. The software menu "Limit value" works with an adjustable differential. The Default Setting of 1 can be modified with parameter 5742 Xsd limit value.

3.9.1 Key Points

1. Limit Values work in a positive sense; this means the output G x (where x is the number of the limit value) turns on when the set point (5741) is exceeded by the input (5740).

2. The limit value turns off when the input falls below (set point 5741 – Xsd 5742). Therefore if 5741 = 20 and 5742 = 2 then G will turn off when the input 5740 falls below 18.

3. Because of point 1 above if limit values are to be used for low temperature protection then the output must be inverted and the set point 5741 becomes the alarm clear value and the alarm setting is the resultant of 5741 less 5742. e.g. For outside frost settings of into frost at 2’C and clear frost at 3’C the following settings must be used:

i. 5741 = 3’C ii. 5742 = 1’C

A Limit Value can be used for frost control by using the following:

1. Create a limit value and observe the correct settings for frost clear and frost active.

2. Reference the G value into a Marker e.g. Marker 1 but choose to invert the G input.

3. Enable the remote control menu and reference the Marker 1 into Remote Day


3.10 Scaling Characteristics Scaling for input B7 is made available. Function With the software menu "Scaling" a new value range can be assigned to an analogue signal via the sub-point "Scaling". The value range is defined by a start and an end value. The scaling can be carried out when the actual values are accessed. The analogue signals B6 to B8 of the ventilation regulator LRP can be scaled. The scaling refers to the value range of the input magnitude. When accessing an analogue signal, the value range can be set with the parameters Start Scaling and End Scaling. Example: A 0..10 V signal should be transformed into 0..350 m3/h.

• Scaled value (represented as 0..100%) • Start scaling = 0.0 (0 %) • End Scaling = 350.0 (100 %) • Set Units to m3/h

The units are modified via the menu option "Modify Text/units" found by displaying the value and selecting the value when in level 4.

3.11 Utilisation time Characteristics The software menu "Utilisation time" can be activated up to three times in the HRP. Function The utilisation times of the week program serve to set the time periods in which the basic program of the HRP is switched to the day control state. Every week program contains four utilization times for every weekday. Every utilisation time is parameterised with a start (time) and end (time). The start (time) from 00:00 and an end (time) of 24.00 is selectable. The parameter week program (N/1, N/2, or N/3) displays whether the respective utilisation time is off = 0 or on = 1. The default menus configure the schedules as follows: Schedule 1 Controls the Optimised Heating Circuit Schedule 2 Controls the DHW Secondary Circulation Pump Schedule 3 Controls the DHW Primary Control Circuit Default Settings for Schedules are as follows: Mon - Fri 0700 to 1600 Sat 0700 to 1400 Priorities Highest priority Holiday program

Special utilization period Lowest priority Week Program N/1, week program N/2, week program N/3 Notice special utilisation periods: The special utilisation periods are a part of the basic program of the HRP or LRP. The special utilisation periods influence the utilisation times of the software menu "Utilisation time/1". Par.No. Parameter Plaintext Lower

3.12 Holiday Characteristics The software menu "Holiday" is active once in the HRP (all HRP types) and the LRP. The holiday dates can be numerous and will be carried over to the following year unless deleted or modified by the user. Function Arbitrary holiday time periods can be entered in the HRP or LRP. Within an entered holiday time period, the basic program is turned OFF. An entered holiday time period is valid every year. The switching time periods entered in the week program N/1 are not valid in holiday operation. Schedules N/2 and N/3 are not configure by default to follow the holiday schedule. In the parameter holiday allowed you can determine whether the holiday program influences the control loop. The menus "Circulation" and "DHW boiler" have a parameter, in which you can stipulate whether the respective function should be active in holiday operation. The parameter "J" BECOMES ""1", as long as the holiday program is currently active. With this function further links can be configured in connection with the holiday operation.

3.13 Modem Characteristics The software menu "Modem" can be activated in the HRP. Function This menu is used for the communication between the HRP/LRP and the BMS central control station via a telephone dialling modem. Modems are available from SyxthSense. The modem is connected via the RS 232 of the HRP. The HRP/LRP BMS communication takes place at a fixed speed of 19200 Bd. Modem connection:

The HRP/LRP modem connection is via the cable DDC 2208.001 Caution: No modem connection can be created via the diagnosis jack on the front of the controller.

Check if a correct connection can be made to the CS140 building control with a telephone. When this is completed, commissioning can be started. Settings of the modem parameter in the HRP/LRP: A prerequisite for a functioning modem connection HRP/LRP BMS is that the “Modem” menu has been enabled in the HRP. Only after this is done is it possible to access and the set the modem parameter via the HRP menu position configuration "Modem". Caution: “GSM-SMS”is not supported in the UK or Ireland Par.No. Parameter Plaintext Lower
