5 Electrical installation work for the heat pump
5.1 Electrical installation work
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.
5.1.1 Electrical installation work
1) The four-core supply cable for the heat pump power part is
fed from the heat pump electricity meter into the heat pump
(for supply voltage, see heat pump manual).
The mains cable is connected to the heat pump contact
plate via terminals X1: L1/L2/L3/ and 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 company blocking contactor or power contactor)
as well as 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 compliance with
the device information).
2) The three-core electricity supply cable for the heat pump
manager (heating controller N1) is fed into the heat pump
(devices with integrated controller) or to the future mounting
location of the heat pump manager (WPM).
The (2~/PE 200 V AC, 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
company blocking contactor or be connected to the
household current, as important protection functions may
otherwise be lost during a utility block.
3) The NO contact of the utility company blocking contactor
(K22) is looped from terminal strip X3.1/G to terminal X3.1/
3. CAUTION! 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 (24 V AC) by the heat pump manager via
terminals X3.3/2 and X3.3/G0.
5) The contactor (K21) for the flange heater (E9) in the
domestic hot water cylinder should be dimensioned
according to the radiator output and must be supplied by the
customer. It is controlled (24 V AC) by the heat pump
manager via terminals X3.3/8 and X3.3/G0.
6) The contactors mentioned above in points 3, 4 and 5 are
installed in the electrical distribution system. The mains
cable for the installed pipe heater must be laid and secured
in accordance with the valid standards and regulations.

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.
Low voltage is applied on the control terminals of N1 and N17
and the 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) All cables must be installed as permanent wiring.
8) The heat circulating pump (M13) is controlled via a coupling
relay (coil voltage 24 V AC). The coupling relay is connected
between the terminals X3.3/3 and X3.3/G0. There is also the
option of using three-phase current circulating pumps. In this
case, the pump module CB 4-1.8 must be used, which is
available as an accessory. The heat circulating pump must
be connected in the module to terminals X2: 1/2/3/PE.
9) The domestic hot water circulating pump (M18) is controlled
via a coupling relay (coil voltage 24 V AC). The coupling
relay is connected between the terminals X3.3/4 and X3.3/
G0. There is also the option of using three-phase current
circulating pumps. In this case, the pump module CB 4-1.8
must be used, which is available as an accessory. The
domestic hot water circulating pump must be connected in
the module to terminals X2: 4/5/6/PE.
10) The return sensor (R2) is integrated into air-to-water heat
pumps for outdoor installation, and is connected to the heat
pump manager via the control cable. The connection takes
place on the terminals: X3.2/3 and X3.2/GND. The return
flow sensor (R2.1) must be installed in the immersion sleeve
in the manifold when a dual differential pressureless
manifold is used. The single-core wires are then connected
to terminals X3.2/2 and X3.2/GND. The link cable located
between X3.2/2 and X3.2/3 as factory default, must be
removed and inserted between X3.2/3 and X3.2/12.
11) The external sensor (R1) is connected to terminals X3.2/1
and X3.2/GND.
12) The domestic hot water sensor (R3) is included with the
domestic hot water cylinder and is connected to terminals
X3.2/4 and X3.2/GND.
ATTENTION!
The control cable is essential for the operation of air-to-water heat pumps
for outdoor installation. The control cable and mains cable are to be
routed separately. It is not permissible for the customer to extend the
control cable.
