Power Failure Protection

In the event that power is lost, the batteries will act as backup, saving your settings and programs.

Error Indicator

If the thermostat is unable to control your system due to an unexpected problem, the thermostat will enter Error Mode. In this
condition, the thermostat flashes "Error" and a code number on the LCD display, and shuts off your system.
To correct this problem:
Take a paperclip and insert it into the "reset hole" on the keyboard of the thermostat. Hold it in for a few seconds until
the display goes blank. Remove the paperclip and the thermostat should reset back to factory condition. If this does not
work, reinsert the paperclip into the "reset hole". While keeping the paperclip in the reset hole, remove the batteries from the
thermostat. Continue holding the paerclip in for 10 seconds then remove it. Replace the batteries with a new set, even if they
have recently been replaced.
Warning: Using the reset hole to clear error mode will reset all programs and settings to factory. Your thermostat will need to
be reprogrammed.
