7.4.3 Installing the strap-on sensor

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

included 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 Hydraulic 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

installed in the immersion sleeve. The remaining empty space

between the sensor and the immersion sleeve must be filled

completely 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

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 to N1-J26 and terminal strip X3; X5. If, due to a

wiring error, the line voltage is mistakenly connected to these ter-

minals, the heat pump manager will be destroyed.

7.5.2 Electrical installation

1) The electric supply 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 electric supply 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 G/24 V AC to connector terminal J5/ID3.

CAUTION! Extra-low voltage!
