The panel must always be supplied with 230V voltage:
- to ensure the anti-grip of the heating pump,
- to ensure Titan Active System® operation when a titanium anode
is protecting the DHW tank.
Use the mode:
- "summer" to shut down the heating.
- "antifreeze" to shut down the boiler if you are to be absent.
Furthermore, if an interactive remote control (CDI 2) is connected
and the 1 switch is in the off
7
position, there will be no display on
the CDI 2.
