Overview Installation Use Maintenance Warranty
9. Connection of optional equipment
Before any operation, make sure to turn the appliance off.
A cable bushing is specifically provided for connections. Be sure to use it.
The use of a 2x0.5mm² multi-strand cable with crimped ends is recommended (not supplied).
Refer to the disassembly instructions on the front cover for accessing the customer's terminal block.
If the appliance is connected to a photovoltaic system, it is possible to store the surplus energy produced by
the photovoltaic system in the form of hot water in the water heater, virtually cost-free. The thermodynamic
water heater only activates the heat pump (PV mode) when it receives the signal from the house's
photovoltaic system. This signal must be set for a trip threshold of 450
W. In this mode, the setpoint
temperature is set to 62° C (not adjustable) and "PV" appears on the display.
When the signal is lost, the thermodynamic water heater automatically returns to the previously selected
operating mode.
For appliances that will be connected to a photovoltaic system, it is necessary to connect the photovoltaic
station to the water heater.
The photovoltaic station is connected to the B1 and B2 terminals of the customer terminal block.
