The compressor must not be forced to
start with periods shorter than 1 start
per 15 minutes.

The compressor heater must have
been switched on for 6-8 hours before

Fighter 2010 is equipped with a soft-starter relay (97)
that limits the inrush current on the compressor to max
24 A.
The compressor must not be forced to start with peri-
ods shorter than 1 start per 15 minutes.
The balance temperature is the outdoor temperature
when the heat pump’s stated output is equal to the
building’s output requirement. This means that the
heat pump covers the whole building’s output require-
ment down to this temperature. Setting of the balance
temperature, additional heating, is made on channel
17.
When using a standard radiator system and with hot
water heating the stop temperature should not fall
below -7 °C. The setting of the stop temperature,
downtime, is done on channel 18.
