NOTE!
The safety equipment must be
installed in accordance with current
regulations for all docking options.
FIGHTER 1330 gives priority to hot water charging at
half power (heat pump module B) via a shuttle valve
(RV). When the water heater/accumulator tank (VVB/
ACK) is fully charged the shuttle valve (VXV) switch-
es over to the heating circuit. When there is a heat
requirement, module A starts first. For larger require-
ments, module B takes care of the heating. The boiler
is connected automatically when the energy demand
exceeds the capacity of the heat pump and the shunt
(SV-P) is activated when the temperature on the boiler
sensor (PG) is above 55 °C.
If VVB/ACK is fitted with an immersion heater (IU) and
a junction box (K11) the Extra hot water function can
be used. A by-pass contactor is recommended.
