ways, some of which are described below.

General
Example FIGHTER 1320 docked with an
oil boiler/pellet boiler and water heater (floating condensing)
NOTE!
The safety equipment must be
installed in accordance with current
regulations for all docking options.
FIGHTER 1320 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)
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
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.
