Frequent questions

"roomERR" appears on the thermostat screen, what do I do?

The DG909 (wired or RF) may display this message when experiencing a sensor error. The reasons for this can be various so we encourage you to contact the Service department or replace the thermostat.

Why is the DG909 not responding to commands or the display is erratic?

When you notice the situation described, press the "RESET" button on the thermostat gently. If the situation has not been resolved, replace the DG909 thermostat batteries with new alkaline ones.

Why is the DG909 (wire/RF) not responding to commands?

Check if your thermostat is locked (the "Lock" symbol on the screen will confirm that the thermostat is locked). Unlock the keys as described in the manual.

I don't know the PIN, how can I unlock the thermostat?

Remove its batteries for an extended period of time (wait more than an hour). Or use a paperclip to press the "RESET" button. Add a new password from the settings menu of your thermostat, whichever solution you choose.

Why doesn't my thermostat display the correct temperature?

The DG909 (wired or radio frequency) may display temperature incorrectly if it has been kept in an environment where it can be directly influenced by external factors. Do not mount the thermostat near passageways, radiators, doors that are always open, exterior walls or windows. Use the setup menu to change the refresh rate of the display information.

"Low battery" is flashing on the screen, why?

The batteries are almost depleted. To enjoy your thermostat, replace the batteries with new alkaline ones. Do not use rechargeable or other batteries.
