9. ConnecJon of opJonal equipment
Water heaters with a coil can be connected to a gas / fuel oil
boiler. In this configuraBon, the water heater commands the
heat generaBon to the boiler.
The connecBon of the boiler has to be made on the contacts
C1
and
C2
of the wiring board.
Always switch-‐off power before any operaJon.
9.1. ConnecJon to a boiler.
A dedicated cable channel exists for the connecJons. Please use it.
To access the wiring board read the instrucBons to remove the front cover.
When associated with a photovoltaic system you can store the
excess energy produced in the water heater as hot water. Once
the photovoltaic panels produce enough energy, the inverter
sends a signal to the water heater which switches into a special
mode ( PV ) acBvaBng the heat pump. If the inverter signal stops,
the water heater switches automaBcally back to the previous
operaBng mode. In this PV mode the set temperature is changed
to 62 ° C (no modificaBon possible) and on the display appears
«PV».
The water heaters linked to a photovoltaic installaBons has to be
connected to the inverter module.
The connecBon to the inverter is done with
B1
and
B2
of the
wiring board.
9.2. ConnecJon of a photovoltaic staJon.
