7.4.3 Installing the strap-on sensor

It is only necessary to mount the strap-on sensors if they are in-

cluded in the scope of supply of the heat pump but have not yet

been installed.

The strap-on sensors can be fitted as pipe-mounted sensors or

installed in the immersion sleeve of the compact manifold.

Mounting as a pipe-mounted sensor

Remove paint, rust and scale from heating pipe.

Coat the cleaned surface with heat transfer compound

(apply sparingly).

Attach the sensor with a hose clip (tighten firmly, as loose

sensors can cause malfunctions) and thermally insulate.

7.4.4 Hot water distribution system

The compact manifold and the dual differential pressureless

manifold function as an interface between the heat pump, the

heating distribution system, the buffer tank and, in some cases,

even the hot water cylinder. A compact system is used to simplify

the installation process, so that a lot of different components do

not have to be installed individually. Further information can be

found in the relevant installation instructions.

Compact manifold

The return sensor can remain in the heat pump, or should be in-

stalled in the immersion sleeve. The remaining empty space be-

tween the sensor and the immersion sleeve must be filled com-

pletely with heat transfer compound.

dual differential pressureless manifold

In order for the heating circuit pumps of the generator and con-

sumer circuits to supply the flow to the return sensor, this must

be installed in the immersion sleeve of the dual differential pres-

sureless manifold.

7.5 Electrical connection

7.5.1 General

During start-up, observe the respective national safety

regulations and the applicable VDE safety regulations,

particularly VDE 0100, as well as the technical connection

requirements of the utility companies (EVU) and network

operators!

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-

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.

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

N1-J11; N1-J19; N1-J20; 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 cable for the output section of the heat pump (up

to 4-core) is fed from the electricity meter of the heat pump

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

pump (see heat pump operating instructions for supply volt-

age). As delivered, the power supply can be taken from a

common mains circuit. As an option, the heat pump and the

second heat generator can be powered by separate cables,

provided that the bridges are removed from the supply termi-

nals (see circuit diagram in the appendix).

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).

When connecting the device, ensure that the incoming sup-

ply has a clockwise rotating field L1; L2; L3.

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).

For detailed information, refer to the circuit diagrams in the ap-

pendix.

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

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

The correct control voltage must be ensured according to

the type plate. 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 contactor or be connected to the household

current, as important protection functions may otherwise be

lost during a utility block.

3) The utility blocking contactor (K22) with 3 main contacts (1/

3/5 // 2/4/6) and an auxiliary contact (NO contact 13/14)

should be dimensioned according to the heat pump output

and must be supplied by the customer.

The NO contact of the utility blocking contactor (13/14) is

looped from terminal strip X3/G to connector terminal N1-J5/

ID3. CAUTION! Extra-low voltage!

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

water cylinder 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

terminals X2/N and N1-J16/NO10.

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

installed in the electrical distribution system. The mains

cables for the heating elements should be dimensioned and

protected according to DIN VDE 0100.

6) All cables must be installed as permanent wiring.

7) The heat circulating pump (M13) is connected to terminals

X2/N and N1-J13/NO 5.

8) The DHW loading pump (M18) is connected to terminals X2/

N and N1-J13/NO 6.
