Night mode timer adjustment procedure
1. If necessary, adjust the Day/Night mode set
points at the desired temperatures. If need
ed, switch from one mode to the other by si
multaneously pressing down the two buttons
and releasing them immediately.
2. From the Night mode, simultaneously press
down the two buttons for more than 3 sec
onds until the icon SET starts to blink, in
dicating that the adjustment of the Night
mode timer is effective. The figures displayed
above the word “AMBIENT” indicate the cur
rent adjustment of the timer.
3. If needed, adjust the timer by pressing down
the right button to increase the value, or the
left button to decrease it. The adjustment
range is from 1 hour to 999 hours. To quickly
scroll through timer values, press and hold
down the button.
4. When the adjustment is completed, release
the buttons and wait for 5 seconds to exit the
adjustment function.
NB :
The Night mode timer will be auto matically
reinitialized to the latest re corded value when
switching from the Day mode to the Night
mode. It is not necessary to readjust the timer
every time you switch to the Night mode. The
timer is also reinitialized when this value is
adjusted.
Once the timer has completed its cycle and
when the thermostat is in the Day mode, you
must manually return to the Night mode. If you
want to automatically return to the Night mode,
the Automatic mode must be selected
Automatic mode
The Automatic mode, which is associated to
the Night mode timer, allows alternating be-
tween the Day/Night modes and the two cor-
responding set points over a 24-hour period.
Once activated, this mode allows an automat-
ic return to the Night mode after 24 hours. The
Automatic mode allows you to define two peri-
ods in a single day with different set points.
For example, if the Automatic mode is activated
and the Night mode timer is set at 8 hours, the
thermostat will be operating in the Night mode
for 8 hours at the night temperature set point.
Then, it will return to the Day mode for 16 hours
operating at the day temperature set point. At
the end of the 24-hour cycle, the thermostat will
return to the Night mode, and the cycle will start
again.
The 24-hour cycle starts with the Night mode as
soon as the Automatic mode is activated. The
Automatic mode activation should be made
when you want to return to the Night mode. The
normal course of a cycle in the Au tomatic mode
is as follows :
1 Night mode : activated for the duration of the
Night mode timer cycle. It returns to the Day
mode when the timer cycle is completed.
2 Day mode : activated for the remaining time
of the 24hour cycle. It returns to the Night
mode at the end of the 24hour cycle.
