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.
Models with Aquaceleris: remove the P.C.B. to a relay discon-
necting connector X5 from the integrated P.C.B. Then, set relay
1 as "Aquaceleris PTC Supply Voltage" and connect resistance
"E11" as indicated.

Attention: to prevent the chiller electronic control from dam-
age, the signal control must not be live. Interrupt a 230V relay
between the chiller and relay board as indicated in the diagram.
