3. Operation (Ambient mode) (Floor mode) Security mode Smart mode Day mode TEST Night mode GFCI button Red Indicator (GFCI Test) First Start-up At the first start-up, the thermostat is initially in the Day and modes. The temperature is displayed in degrees Celsius and the standard factory set point adjustment is 25°C. - Page 8 Temperature set points The figures beside the icon indicate the temperature set points (both in modes). They can be displayed in degrees Celsius or Fahrenheit (see “Display in degrees Cel- sius/Fahrenheit”). Out of any adjustment mode, press down the + button to in- crease the set point, or the - button to decrease it.
- Page 9 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.
- Page 10 Day mode to the Night mode. It is not necessary to read- just the timer every time you switch to the Night mode. The timer is also reinitialized when this value is adjusted. Once the timer has completed its cycle and when the thermostat is in the Day mode, you must manually return to the Night mode.
- Page 11 Adjustment procedure of the Smart mode: 1. First, switch to the Night mode by simultaneously pressing down the + and - buttons and releasing them immediately. 2. From the Night mode, simultaneously press down the + and - buttons for more than 3 seconds, until the icon starts to blink, indicating that the adjustment of the Night mode timer is effective.

When the heating starts or stops, it is normal to hear a “clic” sound. It is the noise of the relay which opens or closes, as applicable. Backlighting The screen lights up when you press down a button. If you do not press down any button for more than 15 seconds, the screen turns off.

Security mode This mode imposes a maximum temperature set point which is impossible to exceed regardless of the mode in progress. However, it is still possible to lower the set point at your dis- cretion.
