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.
