• Operation in the event of a power outage
In the event of a power outage, the chronothermostat 01913 keeps on working normally thanks to the backup batteries

If there is no supply voltage, when the batteries reach a minimum charge level, the display starts blinking to signal that
the chronothermostat is at the shutdown threshold�
