saved in the volatile memory and recovered when power is re-
stored. 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-sufcient for 2 hours. If the power fail-
ure lasts less than 2 hours, the thermostat saves the adjustment
of the hour. However, when power is restored after an exten-
sive failure (more than 2 hours), it recovers the last mode (Man/
Auto/ Pre-Prog) as well as the various adjustments that were ef-
fective when the failure occurred (either from the Ambient or the
Floor mode). The hour and the day of the week are also recov-
ered, but you must update them. The set point will be the same
as what was active when the failure occurred.
N.B.
During the rst 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.
