7.5 Electrical connection

7.5.1 General

All electrical installation work must be carried out by a trained

electrician or a specialist for the specified tasks in accordance

with the

installation and operating instructions,

country-specific installation regulations (e.g. VDE 0100),

technical connection conditions of the energy suppliers

and supply grid operators (e.g. TAB) and

local conditions

To ensure that the frost protection function of the heat pump

works properly, the heat pump manager must remain con-

nected 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.

7.5.2 Electrical installation work

1) The 4-core electrical supply cable for the output section of

the heat pump is fed from the heat pump meter via the util-

ity company blocking contactor (if required) into the heat

pump.

The mains cable is connected at the heat pump switch box

using terminals X1: L1/L2/L3/PE

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 com-

mon 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 supply cable for the heat pump manager

(heating controller N1) is fed into the heat pump.

Connection of the control cable to pin X1.1 “230 V-IN”

(white): L/PE/N.

Details on the power consumption of the heat pump are

listed on both the product information sheet and the type

plate.

The supply cable (L/N/PE~230 V, 50 Hz) for the heat pump

manager must have a continuous voltage. For this reason,

it should be tapped upstream from the utility company

blocking contactor or be connected to the household cur-

rent, because otherwise important protection functions

could be lost during a utility block.

3) 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. 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!

4) The contactor (K20) for the immersion heater (E10) of

mono energy systems (HG 2) should be dimensioned ac-

cording 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).

5) The contactor (K21) for the flange heater (E9) in the do-

mestic hot water cylinder should be dimensioned accord-

ing 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.

6) The contactors mentioned above in points 3, 4 and 5 are

installed in the electrical distribution system. The mains ca-

bles for the radiators should be dimensioned and pro-

tected according to DIN VDE 0100.

7) The heat circulating pump (M13) is connected to pin (5)

(230V) and (8) (control signal) of function block 0 (grey).

8) The domestic hot water circulating pump (M18) is con-

nected to pin (5) of the defined function block.

9) The external sensor (R1) is connected to pin (3) (=U1) of

function block 0 (grey).

10) The domestic hot water sensor (R3) is installed in the do-

mestic hot water cylinder and is connected to pin (3) of the

defined function block

NOTE

ººººº

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 40 m with 2 x 0.75 mm

cables.

NOTE

ºººº

Further information on the wiring of the heat pump manager

is available in the electrical documentation.
