Green: comfort; the set-point temperature has been reached.

If the button shows a steady light, the controller is switched on.
If the button is blinking, the controller is off.
The button remains steady for 10 seconds to show its status, and then it turns off.

23°  Set-point temperature. Using the buttons you can raise or lower the set-point temperature by up to 3°C (in steps of 1°C) with regard to the base set-point temperature defined in Lite settings parameter of the Blueface zero thermostat. (See Zone settings section).
The LED lights indicate the set-point temperature.
In the event that the temperature limit is exceeded, the temperature adjustment icons will flash, indicating that you have reached the limit.

CHANGE OF BATTERY

When the low battery icon appears on the display, the battery must be replaced.

Note: In the case of wireless Lite thermostats, a “Lite low battery” warning message will appear on Blueface zero thermostats.

To replace the battery, separate the thermostat from its base and replace the battery (CR2450).

Important: The use of batteries from leading brands is recommended, similar to those provided. A battery of lesser quality may have a reduced life.

Remember to place the old battery in an appropriate recycling bin.

Note: Remember to remove the anti-vandalism system (if installed) before removing the thermostat from the wall.
