If there is a power cut, the heater will be unable to heat up until power has been restored.
Once power is restored, the heater should not need any input from yourself as the heater has a backup battery remembering the date & time and the settings are held.
If there has been a power cut for several days and the house has gone cold, it may take a few days to heat up the fabric of the building in very cold weather conditions.
If after a power cut, your heater is prompting you to enter the date and time, do this and it will then make the heater work. However, this is a sign that the backup battery for the clock on the heater requires replacing.
Please refer to the instructions for your exact model of heater on how to change this battery - most models will have a battery drawer which slides out and will enable you to change the CR2032 coin cell battery:
