Compatible with low voltage single stage gas, oil or electric heating or cooling systems and single stage

heat pumps. For use on 24VAC systems (not to exceed 30VAC) and 250mv to 750mv millivolt heating

only systems.

WARNING!

• To prevent electrical shock and/or equipment damage, disconnect electric power to system at main

fuse or circuit breaker box until installation is complete.

• Do not use this thermostat on applications with voltages above 30VAC.

• Wiring must conform to all local and national building/electrical codes and ordinances.

• Do not short (jumper) across terminals on the gas valve or at the system control to test the installation.

This will damage the thermostat and void the warranty.

• This thermostat is equipped with automatic compressor protection to prevent damage due to short

cycling. The short cycle protection provides a 5-minute delay between heating (heat pump models) or

cooling cycles to prevent the compressor from being damaged.

• Do not switch the system to cool if the outdoor temperature is below 50 F (10 C). This may damage

the cooling system and may cause personal injury.

• This thermostat should be used only as described in this manual.
