Safety information 4/29

1 Safety information

In the following text, the term calculator covers the heat meter calculator as well as the cold meter calculator and the combined heat/cold meter calculator, if not mentioned otherwise.

Installation and removal must be performed by qualified personnel only

Only ever use under service conditions, otherwise dangers can arise and the warranty may be voided

Breaking the security seal voids the warranty

The 110 V / 230 V versions must only be connected by an electrician

The calculator contains Lithium batteries, so it is not allowed to dispose it with the household waste. Return of the Lithium batteries must be carried out professionally. It is possible to return the product after use for proper disposal to the manufacturer. Please follow the legal regulations at the shipment of Lithium batteries, which rules amongst others the declaration and the packaging of hazardous good.

Lightning protection cannot be ensured; this must be provided by the building wiring

Only one compartment for the power supply must be equipped – do not remove the red locking hatch

2 General information The T550 Ultraheat® (UC50…) calculator is designed for heating and cooling applications. The calculator forms the volumes from the pulses of the flow sensor. The flow and return temperatures are sensed using platinum resistors.

The volume of water and the temperature difference between the flow and return are then calculated and the product is summated.

The result is that the quantity of thermal energy consumed is displayed in the units kWh / MWh or MJ / GJ.

The mounting place and the pulse value of flow sensors with pulse output must correspond to the in the calculator set values (see LOOP 2).

Service loop 2 („LOOP 2“)

In the service loop 2, the installation details are displayed.

Head of the loop

Mounting place of the flow sensor cold side or hot side

Pulse value

At the heat meter or combined heat/cold meter the mounting place of the flow sensor cold side is equivalent to return flow. At the cold meter the mounting place of the flow sensor hot side is equivalent to return flow.

Attention: Calculators with one-time adjustable pulse value and adaptable mounting place being characterized by:

At calculators with one-time adjustable pulse value, the pulse value must be adjusted during commissioning in accordance with the flow sensor and the mounting place must be checked! As long as the pulse value has been set, the calculator cannot cumulate energy and volume. (See „Parameterization of pulse value and mounting place of the flow sensor“)

Installation 6/29

3.1 Examples of installation

3.2 Temperature sensors connection

The temperature sensors PT 100/500 must correspond with the data on the dial plate. The temperature sensors must have an own certification and must be installed at the same circuit such as the flow sensor! The cable length for temperature sensors is limited to 10 m. For installation the temperature sensors the 2nd and 3rd sleeve from the left must be cut, if necessary, to fit the correct cable cross-sections. Unlatch the housing cover by pressing in the side tabs and remove it. Route the cable of the flow sensor from outside through the 2nd sleeve, the cable of the return sensor through the 3rd sleeve. Strip back both cables as shown in the diagram.

Wire-end ferrules

Connect the conductors as shown on the circuit diagram printed on the unit. The 2-wire connection is always made at terminals 5/6 and 7/8 (also when a meter is provided for 4-wire connection). No cable shield must be connected to the meter. Then insert the sensors in the pockets, ball valves, or T-elements and seal against tamper. The end of the sensors must suffice at least by the middle of the pipe cross section. Replace the housing cover and press it in gently until you hear all the tabs latch.

Connection of flow sensor 7/29

4 Connection of flow sensor The flow sensor must be installed at the same circuit as the temperature sensors. When a polarity dependent pulse transmitter is used, take care of the correct orientation. The reference potential must be connected on the right site (-), the positive voltage must be connected on the left spring-type terminal (+).The cable must be fixed to the outer sheath with a clamp for stain relief. If the line has a shielding braid, the shielding braid covering can be pushed over the counter covering of the cable and be connected by a clamp. The cage clamp terminals can be used for cable cross-section of 0.5-1.5mm² (solid or stranded). In order to preserve the IP protection class of the housing, the outside diameter of the cable sheath shall be between 3.7 and 4.4 mm.

Mounting of the calculator The ambient temperature of the calculator must not exceed 55°C. Avoid direct sunlight. The adapter plate can be mounted, for example, on the wall with wall plugs. Then the calculator can be pushed upward and locked in position.

Tariff control (optional) 22/29

13 Tariff control (optional) The following options are available for tariff control.

The summation of the quantity of energy and volume in the standard registers is performed independently of the tariff situation!

Threshold value tariff (tariffs T2, 3, 4, 5, 6)

Tariff registers 1, 2 and 3 can be controlled via up to 3 threshold values.

Either the quantity of energy or the volume can be summated in the tariff registers.

The threshold values can be derived from the flow rate (tariff T2), the power (tariff T3), the return temperature (tariff T4), the flow temperature (tariff T5) or the temperature difference (tariff T6).

Supplied quantity of energy (tariff T7)

In tariff register 1, a quantity of energy is summated that is calculated from the flow temperature (instead of from the temperature difference).

Returned quantity of energy (tariff T8)

In tariff register 1, a quantity of energy is summated that is calculated from the return temperature (instead of from the temperature difference).

Heat/cold meter (tariff T9)

In tariff register 1, the measured quantity of cold; in tariff register 2, the measured quantity of energy is summated. In both cases a threshold can be defined via the flow temperature (“cold threshold”, “heat threshold”).

Temperature above “heat threshold” and temperature difference > +0.2 K --> quantity of heat is acquired

Temperature below “cold threshold” and temperature difference < -0.2 K --> quantity of cold is acquired

Tariff control via timer switch (tariff T10)

For tariff control, one switch-off time and one switch-on time per day can be defined. At the switch-on time, summation of the quantity of energy or volume is started in tariff register 1; at the switch-off time, it is ended.

Tariff control via M-bus (tariff T11)

In tariff registers 1, 2 and 3, either the quantity of energy or the volume can be summated. With the relevant M-bus command, one of the 3 tariffs can be activated or all tariffs can be deactivated.

Surcharge quantity tariff by means of return temperature (tariff T12)

The quantity of energy is summated depending on the return temperature in tariff registers 1 or 2. The summated quantity of energy is calculated from the difference of the return temperature from the defined return temperature threshold (instead of from the temperature difference). Above return threshold: T1 is summated Below return threshold: T2 is summated

Tariff control (optional) 23/29

Display of the tariff situation on the LCD

The current tariff status is shown in the user loop together with the quantity of energy or the volume. No tariff status is shown for tariffs T7 and T8. for tariff T2, T3, T4, T5, T6, T10, T11 and T12

Log functions 25/29

15 Log functions In the internal logbook, metrological relevant events (errors, states actions) are stored in chronological order with their time of occurrence. The events acquired are predefined. The data of the logbook cannot be deleted.

Each event is stored in a separate 4-level shift register; the overflows are transferred to a 25-level circulating buffer. Therefore, at least the last 4 times can be traced for each event.

In a monthly register, the error states are stored for the current month and for the past 18 months (without time stamp).
