2.5 Electrical connection -
indoor unit
The following instructions describe the electrical
connection of the indoor unit.
1. Remove the housing of the upper section by
pushing it upwards and pulling it forwards out
of the slot at the back.
2. Feed the supply line for the indoor unit
through the cable feedthroughs, as well as
the control line between the indoor and out-
door unit, and the cables for the external
devices and probes into the indoor unit.
3. Connect the power supply of the indoor unit
to the terminal strips.
4. Connect all secondary consumers (HGM,
HGU, changeover valves, etc.) to the I/O
module.
NOTICE!
Attach cables in accordance with the connec-
tion schematic and/or the circuit diagram in the
control box.
NOTICE!
Ensure correct polarity when connecting the
electrical leads, especially the control cable.
The number of lines and the sensors is
dependent on the configuration of the heating
system and the components.
Make sure to use enough cable when installing
the indoor unit so that the control box can be
fully lowered for future maintenance.
At the site, avoid adding cable inlets.
