About your new thermostat
Your new Resideo thermostat has been designed to give you many years of reliable service and easy-to-use, push-button climate control.
Features

- Built-in compressor protection
Quick reference to controls
Quick reference to display screen
Cool on: Cooling system is on.
Heat on: Heating system is on.
Aux On: Auxiliary heat is on. (Only for heat pumps with this capability [select models only].)
When “Heat On” or “Cool On” is flashing, compressor protection is engaged (see page 8).
Select the system setting
The SYSTEM switch can be set to control your heating or cooling system, depending on the season.
- Cool: Cooling system control.
- Off: All systems are off.
- Heat: Heating system control.
- Em Heat: Emergency & Auxiliary Heat control. The compressor is locked out. (Select models only.)
Select the fan setting
In “Auto” mode (the most commonly used setting), the fan runs only when the heating or cooling system is on.
If set to “On,” the fan runs continuously.
Adjust the temperature
Note: Make sure the thermostat is set to the system you want to control (heat or cool).
Built-in compressor protection
Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait 5 minutes before restarting.
During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump model). When the safe wait time
has elapsed, the message stops flashing and the compressor turns on.
Battery replacement
Pull at the bottom to remove the thermostat from wallplate.
Turn the thermostat over, insert fresh AAA alkaline batteries, then reinstall the thermostat.
Install two fresh AAA batteries when Lo Batt flashes on the screen. Lo Batt appears for 60 days before the batteries are depleted.
Replace batteries once a year, or when you will be away for more than a month.
The settings are stored in non-volatile (permanent) memory and are thus preserved when the thermostat is without batteries.
