Ambient temperature
The figures displayed above the word “AMBI-
ENT” indicate the ambient temperature, ± 0.5
degree. Temperature can be displayed in de-
grees Fahrenheit or Celsius (see “Display in de-
grees Fahrenheit/Celsius”).
Temperature set point
The figures displayed above the word “SET” in-
dicate the temperature set point. It can be dis-
played in degrees Fahrenheit or Celsius (see
“Display in degrees Fahrenheit/Celsius”).
To adjust the set point, just
press down the right but-
ton to increase the value,
or the left button to de-
crease it. Set points can
be adjusted by increments
of 1°F or 0.5°C. To quick-
ly scroll through the set
point values, press and
hold down the button. The minimum set point is
37°F (3°C), and the maxi mum set point is 86°F
(30°C).
In Day mode, you can turn off the thermostat by
lowering the set point below 37°F. The set point
value displayed will be OFF, and heating system
start up will be impossible.
Day mode and Night mode
The thermostat includes a Day mode and a
Night mode, both of them having their own in-
dependently adjustable and recorded set point.
When switching from one mode to the other, the
system will automatically use the tempera ture
set point corresponding to the Day/Night mode
selected. The standard factory set point adjust-
ment is 68°F (20°C) for the Day mode, and 60°F
(16°C) for the Night mode.
The current Day/Night
mode selection is indi-
cated on the display by
the Sun or Moon icon. In
order to manually switch
from one mode to the oth-
er, simulta neously press
down the two buttons and
release them immediately.
Night mode timer
The Night mode features a timer that automati-
cally returns to the Day mode after a selectable
time period. This timer allows the temporary use
of a temperature set point. The standard factory
adjustment of the timer is 8 hours. With this ad-
justment, the thermostat automati cally returns
to Day mode 8 hours after being switched to
the Night mode.
For example, if you want a night temperature
lower than the day temperature, both Day/
Night modes set points will first have to be set
at the desired temperatures. Before bedtime,
the Night mode temperature set point will be
activated by switching manually to the Night
mode. The timer is set for the duration of the
night. The thermostat will automatically return
to the Day mode at the end of the night, and the
Day mode temperature set point, which is high-
er, will become effective at this time.

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:
1Nightmode:activatedforthedurationofthe
Nightmodetimercycle.ItreturnstotheDay

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 downthe two buttonsforat
least 3 seconds. The Automatic mode icon
will appear. If the Automatic mode was al
readyactivated,thesameprocedureshould

adjustmentfunction.
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.

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.
