Ambient temperature
The figures displayed above the
icon indi-
cate the ambient temperature, ± 0.5 degree.
Temperature can be displayed in degrees Cel-
sius or Fahrenheit (see “Display in degrees Cel-
sius/ Fahrenheit”).
Temperature set point
The figures displayed above the icon indicate
the temperature set point. It can be displayed
in degrees Celsius or Fahrenheit (see “Display
in degrees Celsius/Fahrenheit”).
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 0.5°C or 1°F. To quickly
scroll through the set point
values, press and hold down the button. The
minimum set point is 3°C (37°F), and the maxi-
mum set point is 30°C (86°F).
In Day mode, you can turn off the thermostat
by lowering the set point below 3°C. The set
point value displayed will be --.-, 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
adjustment is 21°C for the Day mode, and 18°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 other, 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 adjustment, 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
higher, will become effective at this time.
