2.6 Electrical connection -
indoor unit
The following instructions describe the electrical
connection of the WKF/WKF-compact indoor units.
1. Remove the cover of the top of keeping it up
push and pull forward from the rear groove.
2. Thread the power cable of the indoor unit -
as well as the control cable between the
indoor- and outdoor units and the cables for
external devices and sensors - though the
cable openings into the indoor unit. Note that
the cable openings in the WKF/WKF-com-
pact 120 series are located above rather than
below.
3. Connect the power supply of the indoor unit
to the terminal blocks.
4. Connect all the secondary consumers (HGM,
HGU, changeover valvs etc.) at 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.
