The ground heat pump only heats the heating circuit.
The electric boiler heats the hot water.
When the ground heat pump cannot cope with the
requirements, the SV1 shunt valve opens towards the
electric boiler.
The electric boiler then supplies additional heat. This
option requires accessory OTS 10.
A permanent resistance of 560 – 820 Ω is installed on
the boiler sensor’s terminal block (31). Not included
with OTS 10
Option 5 – FIGHTER 1110 docked to a
double-shelled water heater (fixed condensing)
