in the volatile memory and recovered when power is restored.
Then, the thermostat enters a very low consumption mode and
only displays the hour and day of the week. All the other functions
are deactivated.
The thermostat is self-sufficient for 2 hours. If the power failure
lasts less than 2 hours, the thermostat saves the adjustment of
the hour. However, when power is restored after an extensive
failure (more than 2 hours), it recovers the last mode (Man/Auto/
Pre-Prog) as well as the various adjustments that were effective
when the failure occurred (either from the
or the mode).
The hour and the day of the week are also recovered, but you
must update them. The set point will be the same as what was
active when the failure occurred.
Note: During the first half hour of the failure, the hour and day
of the week are displayed. After half an hour, the screen
turns off in order to ensure energy saving.
