Power failure
The system remains non-operational for the duration of
a power failure and starts up again automatically when
the power is restored. All the controls settings and
programs are permanently stored. After longer power
failures, the day and time flash on the display and must
be checked (clock power reserve: approx. 5 – 8 hours).
If the power reserve is exhausted, the display jumps to
Monday, 12.00am.
