VVB/ACK Accumulator with water heater
FIGHTER 1310 gives priority to hot water charging at
half power (heat pump module B) via a reversing
valve (VXV). When the water heater/accumulator tank
(VVB/ACK) is fully charged the reversing valve (VXV)
switches over to the heating circuit. When there is a
heat requirement, module A starts first. For larger
requirements, module B takes care of the heating. The
electric 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.
The accessories VST 11, IU and K11 are available for
this option.
