“Terminal diagrams” and “Circuit diagrams” for
the respective model
IMPORTANT
Install electric connections only according to
the terminal diagram and the circuit diagrams
that apply to your model.
IMPORTANT
Ensure clockwise rotary field of the load
power supply (compressor).
Operation with the incorrect rotary direction
of the compressor can cause serious, irrepa-
rable damage to the compressor.
IMPORTANT
The power supply for the heat pump must
be equipped with a three-phase automatic
circuit-breaker with at least 3mm contact
spacing to IEC 60947-2.
Note the level of the tripping current.

IMPORTANT
The sensor cable for heat quantity recording
may not be shortened!
NOTE
The control panel of the heating and heat
pump controller can be connected to a com-
puter or network using a suitable network
cable, enabling the heating and heat pump
controller to be controlled remotely from
there.
If this is required, install a shielded network
cable (category 6, with RJ-45 connector)
through the unit when installing the connec-
tions and run it through the front panel of the
unit, parallel to the existing control cable of
the heating and heat pump controller.
After completing all electrical installation work,
close the switchbox inside the unit.
Screw on the front panel of the unit, if no further
installation work inside the unit is to be carried out
immediately.
