  If the display is blank, it could be due to a lack of power to the heating appliance after installing the Thermostat, preventing the rechargeable battery from charging. Ensure the power supply cable of the heating appliance is connected. It can also happen if the power supply or the communication link between the Thermostat and the heating appliance has been interrupted for more than 8 hours. In this case, check the power supply cable of the heating appliance. After the power is restored, the time may need to be adjusted. If problems persist, contact your installer.

  If a symbol is flashing on the display after the Thermostat has been operating for a while, it indicates that the heating appliance is showing an error. Pressing the button will likely display an error code specific to your heating appliance. Refer to the heating appliance's manual for detailed information about the fault code, or contact your installer.

  A flashing symbol appearing shortly after powering on the Thermostat suggests it's receiving power from the heating appliance but not information. This could be due to: 1. Incorrect wiring: Ensure the Thermostat is connected to the correct OpenTherm connection terminals of the heating appliance. 2. Incorrect Configuration: The heating appliance may not be configured correctly. Contact your installer for assistance.
