The temperature is displayed in degrees Celsius and the standard factory set point adjustment is 25°C. - Page 8 points (both in modes). They can be displayed in degrees Celsius or Fahrenheit (see “Display in degrees Celsius/Fahrenheit”). Out of any adjustment mode, press down the + button to increase the set point, or the - button to decrease it. Set points can only be adjusted by increments of 1 degree.
- Page 9 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. You can switch from the mode to the mode without affecting the timer adjustment. 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.
- Page 10 in the Day mode, you must manually return to the Night mode. If you want to automatically return to the Night mode, the Single programming mode must be selected. Single programming mode The Single programming mode, which is associated to the Night mode timer, allows alternating between the Day/Night modes and the two corresponding set points over a 24-hour period.
- Page 11 is effective. The figures that replace the ambient temperature indicate the current timer adjustment. If needed, adjust the timer by pressing down the + button to increase the value, or the - button to decrease it. The Night mode timer adjustment range is from 1 hour to 23 hours in the Single programming mode.
