Regulations and safety notes

During commissioning, observe the respective country-specific safety regulations and the applicable VDE safety regulations, particularly VDE 0100 as well as the technical connection requirements of the utility companies (EVU) and supply network operators! The heat pump manager should only be operated in dry rooms with temperatures ranging between 0 °C and 35 °C. Ensure that no condensation forms on the device. All sensor connecting cables with a conductor cross-section of 0.75 mm² can be extended to a maximum of 40 m. Sensor cables should not be installed next to power cables. To ensure that the frost protection function of the heat pump works properly, the heat pump controller must remain connected to the power supply and the flow must be maintained through the heat pump at all times.

The switching contacts of the output relay are interference-suppressed. Therefore, depending on the internal resistance of the measuring instrument, a voltage can also be measured when the contacts are open. However, this will be much lower than the line voltage. At the adapter boards -N1/SL, -N1/ML, -N17/LV as well as the pins -N1/J9 .. J14 and J29 and -N17/J6 and J9, an Extra-low voltage is present. If, due to a wiring error, the line voltage is mistakenly connected to these terminals, the heat pump manager will be destroyed.

Electrical installation work for the heat pump
Electrical installation work

1. The electrical supply cable for the output section of the heat pump (up to 5-core) is fed from the electricity meter of the heat pump via the utility company blocking the contactor (if required) into the heat pump (see heat pump operating instructions for supply voltage). An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company blocking contactor or power contactor) and an all-pole circuit breaker with a common Tripping for all external conductors must be installed in the power supply for the heat pump (tripping current and characteristic in compliance with the device information).
2. The three-core electrical supply cable for the heat pump manager (N1) is fed into the heat pump (a device with an integrated controller) or to the future mounting location of the heat pump manager (WPM).
3. The supply cable (L/N/PE~230 V, 50 Hz) for the heat pump the manager must have a continuous voltage. For this reason, it should be tapped upstream from the utility company blocking the contactor or be connected to the household current, because otherwise important protection functions could be lost during a utility block.
4. The utility company blocking contactor (K22) with 3 main contacts (1/3/5 // 2/4/6) and an auxiliary contact (NO contact, e.g. 13/14) should be dimensioned according to the heat pump output and must be supplied on-site.
5. The NO contact of the utility company blocking contactor (13/14) is connected to pin (1) (=DI1) of function block 0 (grey). CAUTION! Extra low voltage!
6. The contactor (K20) for the immersion heater (E10) of mono energy systems (2nd heat generator) should be dimensioned according to the radiator output and must be provided on-site. The control (230 V AC) is performed from the heat pump manager, with the function applied via pin (7) (=NO3) of function block 0 (grey).
7. The contactor (K21) for the flange heater (E9) in the domestic hot water cylinder should be dimensioned according to the radiator output and must be provided on-site. The control (230 V AC) is performed from the heat pump manager via pin (7) of the defined function block
8. The contractors mentioned above in points 3, 4, and 5 are installed in the electrical distribution system. The main cables for the radiators should be dimensioned and protected according to DIN VDE 0100.
9. The heat circulating pump (M13) is connected to pin (5) (230 V AC) and (8) (control signal) of function block 0 (grey).
10. The external sensor (R1) is connected to pin (3) (=U1) of function block 0 (grey).

HNINOWTEEIS

If three-phase pumps are implemented, a power contactor can be controlled via the 230 V output signal of the heat pump manager. Sensor cables can be extended up to 50 m with 2 x 0.75 mm
cables.

HNINOWTEEIS
Further information on the wiring of the heat pump manager is available in the electrical documentation.

CAUTION!
The communication cable is necessary for the function of air and water heat pumps in outdoor installation. It must be shielded and laid separately from the main cable. It is connected to N1-J25. For further information, see electrical documentation.

Functions
In its basic configuration, the heat pump manager WPM Touch has a non- modifiable pin assignment for the function “General 1st unmixed circuit” on the “grey” function block. Further functions can be individually assigned on three function blocks (yellow, green, red) (see Cap. 4.2.1 on page 8). If these three function blocks are not sufficient, it is possible to add two further function blocks (orange, and blue) with the expat expansion which is available as a special accessory. A maximum of five function blocks are possible (yellow, green, red, orange, blue).

HNINOWTEEIS
The “Active cooling” function can only be selected for a reversible heat pump.

Connection of electronically regulated circulating pumps
Electronically regulated circulating pumps may have high starting currents, which may reduce the service life of the heat pump manager. In the event of a high or unknown starting current value, a coupling relay must be installed. The coupling relay must be supplied on-site. This is not necessary if the maximum permissible operating current of the heat pump manager (see information in electrical documentation) is not exceeded by the electronically regulated circulating pump or a relevant approval has been issued by the pump manufacturer.

HNINOWTEEIS
The high-efficiency pumps (UPH) are supplied with the relevant coupling relay for connecting and operating the electronically regulated circulating pump.

CAUTION!
It is not permitted to connect more than one electronically regulated circulating pump via a relay output.

Special accessories
RTM Econ room temperature controller
