IMPORTANT SAFETY INFORMATION WARNING:

• Always turn off power at main fuse or circuit breaker panel before

installing, removing, cleaning, or servicing thermostat.

• Read all the information in this manual before installing this thermostat.

• This is a 24 VAC low-voltage thermostat. Do not install on voltages

higher than 30 VAC.

• All wiring must conform to local and national building and electrical

codes and ordinances.

• To take advantage of the Pop-Up Wizard, power should be applied when

the settings are ready to be entered. Fill in the chart in the Pop-Up

Wizard section before applying power.

• This is a dual powered thermostat that will operate on 24 VAC or batteries.

• 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 connect ground to any terminal in this unit.

• This thermostat is configured with automatic compressor protection to

prevent damage because of short cycling or extended power outages.

Short cycle protection provides a delay between compressor cycles on

heat pumps.

1. Turn off power to heating and cooling system.

2. Remove cover from old thermostat to expose wires.

3. Disconnect wires one at a time from existing terminals. Use enclosed

labels to mark existing wires. Refer to cross references in Table 1 if

existing wiring does not directly match the labels.
