Frequent questions

The DG920 DF displays one of the error messages - ER1, ER2, ER3 or ER4. What is the reason?
When any of the messages are displayed on the floor heating thermostat screen, one of its sensors is experiencing a technical problem. Please contact the Technical Department to check.
The temperature in the room is less than 5ºC, but the programmable thermostat did not turn on the heating, why?
Check that frost protection is active - if it is disabled from the setup menu, the DG920 DF thermostat will not start heating when the temperature has dropped below 5ºC.
The heating hasn't come on, even though the temperature in the home is lower than set, why?
Go to the configuration menu and check which hysteresis is set - to achieve ideal thermal comfort in a short time, we recommend selecting 0.5ºC, so that the heating is switched on if the temperature has dropped by half a degree. If the heating has not started, even if you have checked the hysteresis setting, the sensor for the room may be short-circuited or faulty. Contact the technical department.
The DG920 DF thermostat screen is flashing too bright, what can I do?
The display light intensity can be changed from the setup menu - you can choose any of the values 005 - 100, where 005 is the lowest light intensity.
The battery symbol is displayed on the Homplex 920 DF
To work properly, we recommend replacing the batteries as soon as possible with new, alkaline ones. Do not use batteries.
