6.2 Conduct in the event of a power failure
i
Power reserve (approx. 8 hours)
The current time flashes for approx. 5 minutes in the event of a power
failure and the Troll Comfort DuoFern 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 81.
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.
Data retention following a power failure
All settings remain permanently saved. Data is not lost even after a
longer power failure.
