7.5 Electrical connection

7.5.1 General

All electrical connection 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 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-sup-

pressed. 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.

Extra-low voltage is connected to controller terminals N1-J1 to

N1-J11; N1-J24 and terminal strip X3. If, due to a wiring error, the

line voltage is mistakenly connected to these terminals, the heat

pump manager will be destroyed.

7.5.2 Electrical installation

1) The supply electric cable for the output section of the heat

pump (up to 4-core) are fed from the electricity meter of the

heat pump via the utility blocking contactor (if required) into

the heat pump (see the device information for supply volt-

age).

Connection of the mains cable to the control panel of the

heat pump via terminal X1: L1/L2/L3/PE.

ATTENTION!

Ensure the rotary field is clockwise when connecting the mains cables (if

the rotary field is not clockwise, the heat pump will not work properly, is

very loud and may cause damage to the compressor).

An all-pole disconnecting device with a contact gap of at

least 3 mm (e.g. utility blocking contactor or power contac-

tor) and an all-pole circuit breaker with common tripping for

all external conductors must be installed in the power supply

for the heat pump (tripping current and characteristic in com-

pliance with the device information).

2) The three-core supply electric cable for the heat pump man-

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

nection of the control line to the control panel of the heat

pump via terminal X2: L/N/PE.

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

manager must have a constant voltage. For this reason, it

should be tapped upstream from the utility blocking contac-

tor or be connected to the household current, as important

protection functions could otherwise be lost during a utility

block.

3) The utility blocking contactor (K22) with main contacts and

an auxiliary contact should be dimensioned according to the

heat pump output and must be supplied by the customer.

The NO contact of the utility blocking contactor is looped

from terminal strip X3/G to connector terminal J5/ID3. CAU-

TION! Extra-low voltage!

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

energy systems (HG2) should be dimensioned according to

the radiator output and must be supplied by the customer. It

is controlled (230 V AC) by the heat pump manager via ter-

minals X2/N and N1-J13/NO4.

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

water cylinder should be dimensioned according to the radi-

ator output and must be supplied by the customer. It is con-

trolled (230 V AC) by the heat pump manager via terminals

X2/N and N1-J16/NO 10.

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

stalled in the electrical distribution system. Mains cables for

the installed heaters must be laid and secured in accord-

ance with the valid standards and regulations.

7) All cables must be installed as permanent wiring.

8) The heat circulating pump (M13) is activated via the contact

N1-J13/NO5. The connection points for the pump are

X2/M13 and X2/N. When using pumps where the switching

capacity exceeds the output, a coupling relay must be inter-

posed.

9) The auxiliary circulating pump (M16) is activated via the con-

tact N1-J16/NO9. The connection points for the pump are

X2/M16 and X2/N. A coupling relay is already integrated in

this output.

10) The domestic hot water circulating pump (M18) is activated

via the contact N1-J13/NO6. The connection points for the

pump are X2/M13 and X2/N. When using pumps where the

switching capacity exceeds the output, a coupling relay must

be interposed.

11) The brine or well pump (M11) is activated via the contact N1-

J12/NO3. The connection points for the pump are X2/M11

and X2/N. A coupling relay is already integrated in this out-

put.

12) The return sensor (R2) is integrated into heat pumps for in-

door installation.

The heat pump manager is connected via the following ter-

minals: X3/GND and N1-J2/B2.

13) The external sensor (R1) is connected to terminals X3/GND

and N1-J2/B1.

14) The domestic hot water sensor (R3) is included with the do-

mestic hot water cylinder and is connected to terminals GND

and N1-J2/B3.

The power cable must be run through the guide tubes, inserted

into the side of the control box and secured by means of the

strain relief.
