8.2.3 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.
Remove paint, rust and scale from heating pipe.
Coat the cleaned surface with heat transfer compound (ap-
ply sparingly).
Attach the sensor with a hose clip (tighten firmly, as loose sen-
sors can cause malfunctions) and thermally insulate.

8.2.4 Hot water distribution system
The KPV 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.
DDV 32 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.
8.2.5 Electrical installation of the
heat pump
1) The supply cables for the output section of the heat pump
(up to 5-core) are 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
voltage).
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 cable for the heat pump manager
(heating controller N1) is fed into the heat pump .
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 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 G/24 V AC to connector terminal
J5/ID3. CAUTION! Extra-low voltage!
4) The contactor (K20) for the immersion heater (E10) of
mono energy systems (HG2) should be dimensioned ac-
cording to the radiator output and must be supplied by the
customer. It is controlled (230 V AC) by the heat pump
manager via terminals 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
controlled (230 V AC) by the heat pump manager via termi-
nals 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. The mains cables
for the heating elements should be dimensioned and pro-
tected according to DIN VDE 0100.
7) All cables must be installed as permanent wiring.
8) The heat circulating pump (M13) is connected to terminals
N and N1-J13/NO 5.
9) The DHW loading pump (M18) is connected to terminals N
and N1-J13/NO 6.
10) The brine or well pump is connected to terminals N and N1-
J13/NO 3.
11) The return sensor (R2) is integrated into air-to-water heat
pumps for indoor installation.
The heat pump manager is connected via the following ter-
minals: GND and N1-J2/B2.
12) The external sensor (R1) is connected to terminals GND
and N1-J2/B1.
13) The hot water sensor (R3) is installed in the hot water cyl-
inder and is connected to terminals GND and N1-J2/B3.
