2.6 Electrical connection -
indoor unit
The following instructions describe the electrical
connection of the indoor units.
1. Remove the housing from the upper section
by pressing it upwards and pulling it forwards
out of the rear groove.
2. Guide the supply cable to the indoor units
through the cable openings, and also route
the control line between indoor and outdoor
units and the cables for external devices and
probes into the indoor unit. Note that the
cable openings in the WKF NEO 120 series
are located above rather than below.
3. Connect the mains cable line of the indoor
units to the terminals.
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.
