Off mode with frost protection

EN

When change to Off mode, the icon is displayed and the frost protection is active. The Unisenza Plus Electronic Thermostatic Head actuator will open and close the valve occasionally when the room temperature drops below 5° C in order to avoid the pipe from freezing.

Window open mode
The Unisenza Plus Electronic Thermostatic Head can detect a sudden drop of room temperature, which is possibly caused by the opening of windows nearby. In this situation, the heating system may not be able to maintain the room temperature and thus it should be turned Off to save energy. When the Unisenza Plus Electronic Thermostatic Head operates (except for in Off mode) and it detects a sudden drop of temperature, the device enters Window Open mode. In this mode, the LCD display shows and the actuator will move to close the valve. This mode ends when the room temperature increases or this mode runs for 30 minutes.
This mode can also be ended manually by pressing to change back to normal operation.

Valve protection
If the valve is not opened or closed for a long time may cause scale deposits that may block the valve from moving. The Unisenza Plus Electronic Thermostatic Head has a protection function to fully open or close the valve automatically once every 14 days if no valve movement is detected.

Alert / Error code

When there is fault or alert, the LCD displays
