6.11.3 Connecting the PV Function
This function enables the appliance to operate in
auto-production mode, which means that it will use the
energy produced by the PV function to supply the heat
pump as well as the electrical back-up, in order to heat
the water in the tank.
The connection is made between the PV Inverter and
connectors 1 and 2 on the electronics board.
- Remove the appliance lid.
- Remove the black cover from the electronic board.
- Connect the PV function cable to connector 1 on the
electronic board.
- If the PV function regulator has two control contacts,
connect them to Entrée 1 and 2 on the electronic
board (see Figure 16).
- Terminal 1: a low level of electrical energy is
produced by the PV function.
- Terminal 2: a high level of electrical energy is
produced by the PV function.
