• Always turn off power to the air conditioning or heating system prior to installing, removing,
cleaning or servicing thermostat.
• Read this manual thoroughly prior to installing, programming or operating this thermostat.
• This thermostat is designed for use with a 24 Volt AC low voltage multi-stage heat / cool system.
• Do not use this thermostat on systems with voltages higher than 30 Volts AC.
• This thermostat requires 24 Volt AC Power for normal operation and control of the heating or
cooling system.
• The thermostat also requires two (2) properly installed "AA" alkaline batteries to retain clock
settings in the event of loss of AC Power due to power outage or rolling blackouts.
• Wiring must conform to all building codes and ordinances as required by local and national code
authorities having jurisdiction.
• 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 COOL mode of operation if the outside temperature is below 50˚ F (10˚ C). This
could possibly damage the controlled cooling system and may cause personal injury.
• This thermostat should only be used as described in this manual. Any other use is not
recommended and will void the warranty.
