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 elec-
tric boiler is connected automatically when the energy
requirement exceeds the capacity of the heat pump.
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.
* A safety valve must be installed if the VPA is
equipped with an immersion heater.
