Ambient temperature
The figures displayed above the
icon indi-
cate the ambient temperature, ± 0.5 degree.
Temperature can be displayed in degrees Celsius
or Fahrenheit (see “Display in degrees Celsius/
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 de-
grees Celsius/Fahrenheit”).
To adjust the set point, just
press down the right button
to increase the value, or the
left button to decrease it. Set
points can be adjusted by in-
crements 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 indepen-
dently adjustable and recorded set point. When
switching from one mode to the other, the system
will automatically use the temperature 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,
simultaneously 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 automatically 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.
Night mode timer adjustment procedure
1. If necessary, adjust the Day/Night mode set
points at the desired temperatures. If needed,
switch from one mode to the other by simul-
taneously pressing down the two buttons and
releasing them immediately.
2.
From the Night mode, simultaneously press
down the two buttons for more than 3 seconds
until the icon starts to blink, indicating that
the adjustment of the Night mode timer is effec-
tive. The figures displayed above the
icon
indicate the current adjustment of the timer.
