7.3 Connecting the sensors
Connect the sensors according to the instructions below
before starting up the heat pump. The sensors are
delivered in the manual folder. The sensors have position
markings. Connect the sensors to the heat pump’s
controller. The controller is in the control unit behind the
cover plate.
Outdoor temperature sensor (B9)
Place the sensor in a shaded location on a wall facing north
or north-east. The sensor must not be installed near
windows or doors.
Connect the outdoor temperature sensor (B9) to the T1
connectors X9 and M on the controller.
Room temperature sensor (B5)
Place the room temperature sensor in a central location in
the residential space. The room temperature sensor must
be connected to the controller before the heat pump is
started up.
The room temperature sensor measures the room
temperature, which is displayed on the heat pump’s user
interface, and it also regulates the room temperature. The
impact of the room temperature sensor on the indoor
temperature can be adjusted on the user interface.
Room temperature sensor placement:
Connect the room temperature sensor (B5) to the T3
connectors X8 and M on the controller.
7.4 Connecting the domestic hot water
circulation pump
The domestic hot water circulation pump (Q4) can be
connected to the controller’s electrical control. According
to the factory settings, the water circulation pump operates
whenever the domestic hot water operating method is in
the ON state. The circulation pump’s control method can
be adjusted so that it operates according to a schedule. The
adjustment can be made using the heat pump’s user
interface.
NOTE: The maximum load current on the relay output is
1.5 A (230 V AC)
The water circulation pump is connected to terminal strips
Q4:L, N, PE on the control unit.
7.5 Continuous alert
The heat pump can provide a continuous alert in the event
of failures. The continuous alert is connected to the
controller’s potential-free relay, K10. Use a 2-pole cable
with a cross-sectional area of at least 0.5 mm
2 .
The controller uses indicator lights to show whether it is
functioning correctly and communicate alerts. The device
is functioning correctly when the green light is on. If the
red light is on, the device is in the alert state.
