In case of a power failure, the appliance operates as follows:
In manual mode
After power supply has been restored, operation is continued with the parameters set.
The time and the duration of the power failure is documented in the log memory.
In timer or program mode
In case of an interruption of the power supply of less than 60 minutes, the current pro-
gramme is continued from the point at which it was interrupted. For longer interruptions
of the power supply, all appliance functions (heating, fan etc.) are switched off.

The previous values are restored. If a program has been initiated via remote control, it
is continued.
