Electrical connection
Electrical installation and servicing must
be carried out under the supervision of a
qualified electri cian in accordance with the
stipulations in force.
The sensor and communication cables must
not be routed close to the power cable.
This applies to all external sensors and all
communication cables.
When cable conduit is used for the outdoor
sensor this should be sealed to prevent con-
densation in the outdoor sensor capsule.
NOTE!
NOTE!
Electrical installation
The cable for incoming power shall enter from the rear as
set out in the figure.
The sensor inputs and communication connection are
of the type SELV. Sensors cables must not be routed
together with power cables. Cables may be taken out
from the rear of the heat pump.
Connection of external sensors
See respective Description of functions for connection of
external sensors.
For example, for the flow sensor (FG), return sensor (RG),
outdoor sensor (UG) see Description of functions - Basic

Reset the miniature circuit-breaker and the
motor cut-out. They may have tripped during
transportation.
NOTE!
Miniature circuit-breaker
Control system, circulation pumps and their wiring, are
internally fuse protected with a 2 pole miniature circuit
breaker –F1 (1).
Resetting
Miniature circuit-breaker -F1 (1) and is accessible on the
reverse of the heat pump (see image).
Motor cut-out
The heat pump is equipped with two motor protection
breakers. The motor protection breaker cuts the power to
the relevant compressor if the current is too high for one of
the compressors.
Motor protection can also be deployed by the pressostats
LP2 (41b) and HP2 (33b), breaks if the pressure is too low or
too high.
Motor protection breaker -Q1A (26a) breaks the current
supply to compressor A.
Motor protection breaker -Q1B (26a) breaks the current
supply to compressor B.
Resetting
Motor protection breaker -Q1A (26a) and -Q1B (26b) are
accessible on the reverse of the heat pump (see the fig-
ure). The breaker is reset by twisting the control knob to
horizontal position.
