Failover: power under control

With the Failover module installed (Chapter 7), the Aquarino starts to see the mains supply: voltage, current and consumption. And when the power goes out, it executes a plan you defined calmly — instead of leaving the UPS to cope with everything switched on.

23.1 What happens in an outage

1. The equipment detects the voltage outside the normal range (below 70% or above 130% of nominal — universal voltage, detected automatically).
2. The battery icon lights up in the status bar and you receive the *"Energy Failure"* e-mail.
3. The outlets without no-break permission (Chapter 11) are turned off — the non-essentials come off the battery.
4. The outlets in Failover mode turn on — the emergency air pump takes the stage.
5. When the power returns, everything goes back to its programmed state, and the *"Energy Restored"* e-mail arrives.

23.2 Power consumption

The Failover also enables the Volts, Amps and Power sensors: mains voltage, total current and consumption — including the accumulated kWh, with a resettable counter. You get to know, in hard currency, how much the aquarium adds to the electricity bill each month.
