A
The unit's scope of delivery includes
a five metre long, four-core control
line for connecting the indoor unit
to the outdoor unit. The control line
to the outdoor unit contains a data
cable which makes communication
between the indoor unit and the
outdoor unit possible. This is used
for controlling cooling and heat-
ing output and for forwarding fault
indications to the indoor unit.
If the length is insufficient, you can
extend these control lines on the
indoor unit.
■
We recommend to install a main
/ repair switch on the building
near the indoor unit.
■
The terminal blocks for making
the connections are located at
the rear of the unit. When the
unit is installed, measurements
can be made from the front by
removing the cover.
■
If an optional condensation
pump is used in conjunction
with the unit, it may be neces-
sary to install an additional relay
with a higher contact rating
after the switch-off contact
on the pump to switch off the
compressor.
4. Connect the control line that has
been pre-prepared on-site to the
terminals (see electrical connec-
tion diagram P. 22).
5. Connect the on-site pre-prepared
control line with the supplied
control cable in a professional
manner.
6. Insert the control line plug into
the corresponding socket on the
outdoor unit.
7. Re-assemble the unit.
