WIRING DIAGRAM WITH HEATING PHASE ACTIVE.
The boiler is set up for the management of any external pump,
the pump is powered in concomitance with the heating request
phase.
All the relays can be configured as an active central heating
phase. The diagram represents the connection on relay 2. In the
event this relay is used, it is necessary to jump pins 57 and 58 of
connector X25 positioned on the relay board.
In addition, the possible connection to relay 1 and relay 3 is
represented.

WIRING DIAGRAM WITH GENERIC ALARM AND
EXTERNAL GAS VALVE.
The boiler is set up for the management of any generic 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 of connector X25 positioned
on the relay board. While relay 3 is configured as an external
gas valve supply.
The ''generic alarm'' signal is enabled whenever one of the en-
visioned anomalies occurs in the boiler (see boiler book under
''Troubleshooting''). The ''external gas valve supply'' control is
enabled together with a burner ignition request in the boiler.
