Troubleshooting
SYMPTOM: The backlight on the thermostat
doesn’t stay on continuously, it only stays
on for 10 seconds after a button press.
CAUSE: The backlight is turned OFF in Advanced
Setup or a common wire is not connected.
REMEDY: To turn ON the backlight see Advanced
Setup on page 16 or 17 of the Owner’s Manual.
To connect a common wire see pages 8-13
of this manual.
SYMPTOM: The slide switches on the thermostat
are very difficult to move.
CAUSE: The backplate of the thermostat is
deformed by being screwed tightly into a
wall that is not perfectly flat.
REMEDY: Loosen the screws holding the
thermostat into the wall.
