Adjustment procedure of the Automatic mode:
1. If necessary, adjust the Day/Night set point at
the desired temperatures. If needed, switch
from one mode to the other by simultane-
ously 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 starts to blink, indicat-
ing that the adjustment of the Night mode
timer is effective. The figures displayed
above the icon indicate the current timer
adjustment.
If needed, adjust the timer by pressing down
the right button to increase the value, or the
left button to decrease it. The Night mode
timer adjustment range is from 1 hour to
23 hours in the Automatic mode. To quickly
scroll through the timer values, press and
hold down the button. NOTE: If you set the
timer to any value exceeding 23 hours, it
will be impossible to activate the Automatic
mode and if it was activated, the Automatic
mode will be deactivated.
3. Activate the Automatic mode by simultane-
ously pressing down the two buttons for at
least 3 seconds. The Automatic mode icon
will appear. If the Automatic mode was al-
ready activated, the same procedure should
be used to deactivate it.
4. When the adjustment is completed, release
the buttons and wait for 5 seconds to exit the
adjustment function.
NOTE: It is always possible to manually
change the Day/Night mode during a 24-hour
cycle. However, any manual return to the
Night mode will re-initialize the Night mode
timer to the latest value recorded, which
modifies the cycle in progress. In all cases, at
the end of the 24-hour cycle, the thermostat
will return to the Night mode and start a new
cycle. It is thus not necessary to readjust the
Automatic mode when a manual change is
made to the Day/Night mode.
