Overview Installation Use Maintenance Warranty
A solar heating station can be connected to the water heater
(unit with heat exchangers in "solar" mode). In this configuration,
the water heater only operates when it receives a signal from the
solar station. After receiving the signal, the heat pump will start if
heating is required and if the operating and air ranges allow it. If
the heat pump can not start, the electrical backup will take over
if it is in an operating range (permanent or programming).
Note: A solar thermal station signal and a PV signal can not be
connected simultaneously.
The solar station is wired to the B1 and B2 terminals of the
customer terminal block.
