ule.
9.1.1
Cable cross sections/types
All cable cross sections/types must be specified on site by a professional
electrician, in compliance with applicable DIN standards. Use a shielded
cable for the BUS.

The electrical connection is performed on the terminal of the indoor module.
Follow the wiring diagram.
9.2.1
Installing external wall sensor
Install external sensor (included in delivery) always vertically (even if tempo-
rary), with cable entry pointing downward. Next, screw connection must be
tightened enough to allow sealing insertion of cable and to prevent water
from entering the housing.
When performing temporary installation, sensor might have to be mounted
on board, which is fastened to wall using a steel nail.
To prevent transport damages, front and side panels of heat distribution
station are separately enclosed.
After all connections are completed, install plates at specified positions (in-
sert and press)
9.2.2
Power supply
- Heating element
The power supply (230 V or 400 V) is selectable. The power supply is de-
fined by linking the terminals on the control board.
9.2.3
Heating element - thermostat setting
The thermostat of the heating element is permanently set on 75 °C. Con-
nection and disconnection takes place via the heat pump controller. The
electric resistance heater has a safety temperature limiter. In case of trigger-
ing, it must be reset manually. To reset use the button on the bottom of the
safety temperature limiter (under the cap).
