6.2 Conduct in the event of a power failure
Power reserve (approx. 8 hours)
The current time flashes for approx. 5 minutes in the event of
a power failure and the DuoFern room thermostat changes to
power reserve.
Time and date after a power failure
The power reserve is approx. 8 hours. If this time is exceeded,
the time and date are lost and need to be reset, see page 77.
i
The internal timer works with tolerances in power
reserve mode. It may therefore be necessary to adjust
the time after a longer power failure.
i
Data retention following a power failure
All settings remain permanently saved. Data is not lost even
after a longer power failure.
