IMPORTANT SAFETY INFORMATION

WARNING:

■ Always turn off power at the main power source by unscrewing fuse or switching circuit breaker to the off position

before installing, removing, or cleaning this thermostat.

■ Read all of the information in this manual before programming this thermostat.
■ This is a 24V AC low-voltage thermostat. Do not install on voltages higher than 30V AC.
■ All wiring must conform to local and national building and electrical codes and ordinances.
■ Do not short (jumper) across terminals on the gas valve or at the system control to test installation. This will

damage the thermostat and void the warranty.

■ Do not switch system to cool if the temperature is below 50°F (10°C). This can damage the cooling system and

may cause personal injury.

■ The thermostat will not control your heating/cooling system without power. It requires four charged “AA” Energizer

brand batteries or equivalent alkaline batteries for thermostat operation, and a continuous 24V AC circuit for proper
system control.

■ Replace batteries every year or when “LO BATT” indicator appears on the thermostat display.
■ Use this thermostat only as described in this manual.
