Behaviour On The Failure And Reinstatement Of The Bus Power Supply - Gewiss Chorus EIB GW 10 793 Manual Del Usuario

and reinstatement of the bus power supply
When the bus power supply fails, the device performs no actions. The time and date are
maintained by the buffer power system (rechargeable battery) whilst all the other settings
are saved to a non-volatile memory. When the power is supplied by battery only, the
device has an autonomy of 36 hours in the following conditions:
• time display active;
• measure and temperature display not active (dashes are displayed);
• backlighting inactive;
• front keys are not enabled (except for the simultaneous pressing of FAN and SET).
When there is no bus power the simultaneous pressing of FAN and SET for 2 seconds
will cause the rechargeable battery to disconnect inside the device. This function is used
to conserve the efficiency of the battery when the device is not used for a long period.
The battery is then automatically reconnected when the device receives power from the
bus. The set programs are not lost when there is a failure in the bus connection or when
the battery is disconnected.
The device is in full operating mode within a maximum of 5 seconds from reinstatement
of the bus power supply.
If the buffer power (rechargeable battery) is absent or disconnected, the thermostat will
restart in OFF mode when the bus power is reinstated.
