Alarm relay output of control unit
The FIL-SPL boiler can activate a potential free changeover contact when an alarm is detected. Connect an
alarm indication to X:22 (common), X:23 (NC), X:24 (NO). During the alarm, the X:22-24 are connected.
The initial cause of an alarm will be identified on the display. Possible issues that generates an alarm:

Malfunction of the temperature sensor of the boiler

Issue in observation of internal power consumption (needs accessory)

Low supply voltage of control unit (nominal - 10 %)
Note! Remember to add warning label of external control voltage!
Note! The alarm relay output can have maximum load of 2 A (230 V AC) in total.
Alarm relay output of the main switch
The FIL-SPL boiler has an extra alarm relay in the main switch. If the main switch trips for some reason, the
changeover contact in the main switch can be used as an alarm source for example for building
automation. Connect the alarm from the main switch to X:25 and X:26 (NO). During the alarm, the X:25-26
are connected.
Possible issues that generates an alarm:

Overload in the main switch

Temperature limiter

Dry-boiling preventer (models from 120 kW to 1600 kW)
Note! Remember to add warning label of external control voltage!
