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 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 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 heating

and cooling cycles on heat pumps.

Detailed mounting and wiring instructions are explained in the Installation

Manual.

Refer to the pop up wizard section in the installation manual for a

complete list of factory defaults and contractor settings.

Providing Power to the Thermostat

For wiring diagrams refer to the Installation Manual.

The thermostats will operate using 24V AC or two AA batteries. When

the two AA batteries are installed the thermostat will continue to run if

the 24V AC fails.
