Lock option
It is possible to impose a maximum tempera-
ture set point by activating this mode. Then, it
becomes impossible to exceed this set point,
regardless of the mode. However, it is still pos-
sible to lower the set point at your discretion.
Locking procedure
1. From the Day mode, adjust the set point at
the maximum desired value.
2. From the Day mode, simultaneously press
down the + and – buttons for more than 10
sec onds, until the Lock icon displays (note
that the SET icon will also blink after 3 sec
onds).
3. Release the buttons. The thermostat is now
locked.
Unlocking procedure
1. Cut off the power supply of the thermostat at
the electrical panel.
2. Wait at least 20 seconds.
3. Restore the power supply of the thermostat
at the electrical panel.
4. The Lock icon is blinking on the thermostat
display, meaning that it is possible to unlock
the thermostat.
5. While the Lock icon is blinking, simultane
ously press down the + and – buttons for
more than 10 seconds, until the Lock icon
disap pears.
6. Release the buttons. The thermostat is now
unlocked.
NOTE : If the thermostat isn’t unlocked within 5
minutes after the restoration of the power sup-
ply, the Lock icon will stop to blink and it will be
impossible to unlock the thermostat unless cut-
ting off the power supply again.
Heating power indicator
The level of power used to maintain the tem-
perature at the set point is expressed as a per-
centage indicated by the number of bars in the
thermometer displayed. The heating power
used is displayed as follows :
0 bar = no heat
1 bar = 1% to 25%
2 bars = 25% to 50%
3 bars = 50% to 75%
4 bars = 75% to 100%
Power failure
In the case of a power failure, the adjustments
are automatically saved and recovered when
power is restored. Note that the Day/Night
mode is recovered only if the Automatic mode
was previously deactivated. Otherwise, the
thermostat comes back in Day mode and the
Automatic mode icon blinks, meaning that the
Automatic mode was previously activated and
that it is now deactivated. Blinking will stop as
soon as a button is pressed down.
