Day mode and night mode
The thermostat includes a Day mode and a Night mode, both of them
having their own independently 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 (70°F) for the Day mode, and
18°C (64°F) for the Night mode.
The current Day/Night mode selection is indicated 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 automatically 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 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
simultaneously 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 Moon icon blinks and the letter H appears.
3. If needed, adjust the timer by pressing down the top button to increase
the value, or the bottom button to decrease it. The adjustment range is
from 1 hour to 999 hours. To quickly scroll through timer values, press
and hold down the button.
4. When the adjustment is completed, release the buttons and wait for
5 seconds to exit the adjustment function.
