Power supply failure
During power supply fail, the Fumis ALPHA controller remains active due to internal battery. Internal status remains as
it was before the power failure. Internal electronics runs in power saving mode consuming very low battery power
(approx. 10nA) thus allowing very long battery life (10 years min).
In case of a power supply failure the Fumis ALPHA controller operates as follows:
Duration of power
supply failure
Operation before the power
supply failure
Operation after the power supply failure
Less than 2 minutes
Fire Up phase
The controller continues normally
Burning phase
The controller checks the air/water temperature
and continues in the Burning phase, or restarts in
