Frequent questions

Why is the Homplex 909 (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.

Why is the Homplex 909 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 Homplex 909 thermostat batteries with new alkaline ones.

Why doesn't my thermostat display the correct temperature?

Homplex 909 (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.

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

Homplex 909 (wired or RF) may display this message when experiencing a sensor fault. The reasons for this can be various so we encourage you to contact the Service department or replace the thermostat.

"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.

What does the first function in the menu, the "CL" function, do?

The first function in the menu (temperature sensor calibration, CL, default 0) allows you to adjust the temperature displayed/measured by the thermostat. You may, for example, want to synchronize the thermostat with a weather station that is a few degrees off, or the thermostat may not be indicating the temperature correctly. You can adjust the thermostat's display minus or plus 4 degrees. If your thermostat reads 23 degrees and the station reads 24, change the value in this menu to 1 and your thermostat will display 24. From this point on the thermostat's actions (heating on/off) will be related to this altered temperature.
