When many power consumers are connected in the
property at the same time as the electric additional
heat is in operation, there is a risk of the property’s
main fuses tripping. Control module has an integrat-
ed load monitor that controls the power steps for the
electric additional heat by disconnecting step by step
in event of overload in a phase. Reconnection occurs
when other current consumption is reduced.
A current sensor (BE1 - BE3) must be installed on
each incoming phase conductor into the electrical
distribution unit, to measure the current. The electri-
cal distribution unit is an appropriate installation point.
Connect the current sensors to a multi-core cable in
an enclosure next to the electrical distribution unit.
Use unscreened multi-core cable of at least 0.5 mm²,
from the enclosure to control module.
Connect the cable to the input board (AA3) on termi-
nal block X4:1-4 where X4:1 is the common terminal
block for the three current sensors.
The value for the size of the fuse is set in menu 5.1.12
to correspond with the size of the property’s main
fuse. Here it is also possible to adjust the current
sensor’s transformer ratio. Enclosed current sensors
have a transformer ratio of 300 and, if these are used,
the incoming current must not exceed 50 A.

CAUTION
The voltage from the current sensor to the input
board must not exceed 3.2 V.

If the current value is set too low, it may turn off the
electric heater / heaters and reduce the heat pump’s
power.
