Wiring diagram with generic alarm and
external gas valve.
The boiler is set up for the management of any ge-
neric alarms. In addition, it is possible to connect
an external gas valve to be connected to an LPG
tank. All relays can be configured as a generic
alarm and as an external gas valve.
The diagram shows relay 2 as a generic alarm. In
this case it is necessary to jump pins 57 and 58
