remaining  on  the  night  time-switch  and  the  current  Day/Night  mode.  These 

parameters are saved every minute if any changes are made, except for the Day/

Night mode and the remaining time left on the time-switch. These are saved only 

if the Single programming mode had not been activated.
Please note that the Single programming mode is not automatically reactivated 

when the thermostat is turned on. The 

 icon blinks to warn the user that the 

mode was previously activated when the thermostat was shut off but is no longer 

active.  Furthermore,  when  power  is  shut  off,  the  existing  Day/Night  mode  is 

recovered only if the Single programming mode was previously deactivated. In 

the opposite case, the Day mode is automatically reactivated. The Security mode 

is also reactivated if it was previously activated. However, the icon will blink for 

5 minutes, during which it is possible to deactivate the Security mode by pressing 

down both buttons simultaneously for 13 seconds. If this is not done, the Security 

mode will remain activated and the icon will stop blinking.

night light (only for model with backlight)

You can activate the Night light option to permanently turn on the backlight. To 

activate or deactivate this mode, the thermostat must first be set in Day mode. 

Then, simultaneously press down both buttons for 3 seconds until the backlight 

blinks. Release the buttons. The night light mode will be activated (or deactivated 

if it was previously activated).
