Resetting the Thermostat or Thermostat Settings
If the thermostat has good batteries, but has a blank display or does not respond to key
presses, the thermostat should be reset by removing the batteries for 2 minutes. This reset
will not change the menu settings or program. If the condition persists after reinstalling the
batteries, replace the thermostat.
To conveniently reset only the schedule and user settings back to factory defaults, press Menu
and Backlight buttons at the same time and hold until the display goes blank and resets.
