Heating
The supply of heat to the building is controlled by the
control computer settings (curve slope and offset).
After adjustment the correct amount of heat for the
current outdoor temperature is supplied. The heat
pump flow temperature (WW-out) will hover around
the theoretical required value (the value in brackets on
the display). For subnormal temperatures the comput-
er calculates a deficit in the form of degree minutes,
which results in the acceleration of heat production.
The larger the subnormal temperature, the greater the

heat production.

Control, normal
The heat pump's control computer can control an
external electric boiler/cassette in up to seven power
steps, or an external oil-fired boiler and mixingvalve.
Control, double curves
Curve 1 controls the operation of the compressors.
Curve 2 controls an external mixing at lower tempera-
tures. In this operating instance the supplement is limit
to one step.
Controls
When fitted with the Hot water control accessory and,
for instance, our hot water accumulator VPA, the
FIGHTER 1310 can be used for hot water production.
In those cases connection to the water heater has
been made via the accessory Hot water control and
external immersion heaters, are installed in the water
heater the function Extra hot water can be utilised.
This function increases the hot water temperature
from the normal 50 °C up to approx. 60 °C with the
help of the immersion heater.
The brine pump is in operation when one of the com-
pressors is in operation and when the selector switch
for brine pump (40) is in the Auto position.
FIGHTER 1310 can be docked with an external unit
with its own automatic heating control system. FIGHT-
ER 1310 then delivers heat up to a fixed temperature
level. This is known as fixed condensation. To regu-
late the room temperature, see the instructions for the
external units.
