the Day mode for 16 hours operating at the day tem-
perature set point. At the end of the 24-hour cycle,
the thermostat will return to the Night mode, and the
cycle will start over. The 24-hour cycle starts with the
Night mode as soon as the Smart mode is activated.
The Smart mode activation should be made when
you want to return to the Night mode. The normal
course of a cycle in the Smart 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
24-hour cycle. It returns to the Night mode at the
end of the 24-hour cycle.
Adjustment procedure of the Smart mode:
1.
If necessary, adjust the Day/Night set point at
the desired temperatures. If needed, switch from
one mode to the other by simultaneously press-
ing down the two buttons and releasing them
immediately.
2.
From the Night mode, simultaneously press
down the two buttons for more than 3 seconds. If
needed, adjust the timer by pressing down the top
button to increase the value, or the bottom but-
ton to decrease it. The Night mode timer adjust-
ment range is from 1 hour to 23 hours in the Smart
mode. To quickly scroll through the timer values,
press and hold the bottom button.
NOTE: If you set the timer to any value exceeding
23 hours, it will be impossible to activate the
Smart mode and if it was activated, the Smart
mode will be deactivated.
3. Activate the Smart mode by simultaneously press-
ing down the two buttons for at least 3 seconds.
The
icon will appear. If the Smart mode was
already 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 adjust-
ment 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 Smart mode when a
manual change is made to the Day/Night mode.
When turning back on after being powered off
(because of a power failure, for example), the
Smart mode is deactivated, and, if previously
activated, the
icon will blink. The blinking
will stop as soon as you press down a button.
Display in either degrees Celsius/
Fahrenheit
The thermostat can display the ambient temperature
and the set point in degrees Celsius (standard factory
setting) or Fahrenheit.
1. From the Day mode, simultaneously press down
the two buttons for 3 seconds. The Celsius/
Fahrenheit symbol will blink after 3 seconds. (For
the backlit models, press down the two buttons for
8 seconds. Note that the backlight will blink after
3 seconds, but you must hold down the buttons.
The Celsius/Fahrenheit symbol will blink after 8
seconds.) Release the buttons.
2. Press down the top button to switch from the de-
grees Celsius to the degrees Fahrenheit, and con-
versely. The degree Celsius or Fahrenheit symbol
will be displayed.
3. When the adjustment is completed, release the
buttons and wait for 5 seconds to exit the adjust-
ment function.
