Warning
Read Before Testing
• Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board
to test the thermostat installation. This could damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below 50º F (10º C). This could
possibly damage the controlled cooling system and may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential damage to the
compressor from short cycling. When testing the system, make sure to take this delay into account.
NOTE: The compressor delay can be bypassed by pressing the reset button on the front of the thermostat.
All user settings will be returned to factory default, however all Installer settings will remain as originally
programmed in section 4.
