Installation Guide

IMPORTANT SAFETY INFORMATION WARNING:

• Always turn off power at the main power source by unscrewing the fuse or switching the circuit breaker to the off position before installing, removing, cleaning, or servicing the thermostat.
• Read all of the information in this manual before installing or 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.

Features

• Four setpoints for weekday programming—two setpoints for weekend comfort.
• Two AA ENERGIZER brand batteries retain program memory even during power outages.
