About your new thermostat
Congratulations on the purchase of your new Honeywell thermostat. It has been designed to give you many years of reliable service and easy-to-use, push-button climate control.

Features

One-touch temperature control. Large, clear, backlit display is easy to read even in the dark. Displays both room temperature and temperature setting. Removable battery holder for fast, easy replacement. Built-in compressor protection.
This thermostat is ready to go!
Your new thermostat is pre-programmed by the installer and ready to use. Just check the settings below and change if needed: 1 Fan (Auto/On): Preset to Auto..To change, see page 6 Auto is the most commonly used setting, but you may prefer On for improved air circulation. 2 System (Heat/Cool/Auto/Em. Heat): Preset to Heat..To change, see page 7 You can select heating or cooling, or set the system to control both systems automatically, if needed.

Compressor is locked out.

Auto Changeover (heat/cool)

Fan Auto System Auto

Auto Changeover is a feature used in climates where both air conditioning and heating are used on the same day.When the system is set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 3 degrees apart.The thermostat will automatically adjust settings to maintain this 3-degree separation (called deadband). The 3-degree separation between heating and cooling set temperatures is fixed, and cannot be changed.
Press until screen displays Auto
Note: The Auto system setting may not appear, depending on how your thermostat was installed.
Built-in compressor protection

Cool On System

Cool Setting
This feature helps prevent damage to the compressor in your air conditioning or heat pump system. Damage can occur if the compressor is restarted too soon after shutdown.This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump).When the safe wait time has elapsed, the message stops flashing and the compressor turns on.
Message flashes until safe restart time has elapsed

Battery replacement

Press and pull to remove
Insert fresh AA alkaline batteries, then reinstall battery holder
Batteries are optional (to provide backup power) if your thermostat was wired to run on AC power when installed. Install fresh batteries immediately when the REPLACE BATTERY warning begins flashing.The warning flashes about two months before the batteries are depleted. Even if the warning does not appear, you should replace batteries once a year, or before leaving home for more than a month. Batteries provide backup power to the display during power interruptions.All other settings are permanently stored in memory, and do not require battery power.

In case of difficulty

If you have difficulty with your thermostat, please try the suggestions below. Most problems can be corrected quickly and easily.
Display is blank Check circuit breaker and reset if necessary. Make sure power switch at heating & cooling system is on. Make sure furnace door is closed securely. If thermostat is battery powered, make sure fresh AA alkaline batteries are correctly installed (see page 10).

Temperature settings do not change
Make sure heating and cooling temperatures are set to acceptable ranges: Heat: 40 to 90F (4.5 to 32C). Cool: 50 to 99F (10 to 37C).
Heating or Press SYSTEM button to set system to Heat. Make sure the temperature cooling system is set higher than the Inside temperature. does not respond Press SYSTEM button to set system to Cool. Make sure the temperature is set lower than the Inside temperature. Cool On or Heat On is flashing Check circuit breaker and reset if necessary. Make sure power switch at heating & cooling system is on. Make sure furnace door is closed securely. Wait 5 minutes for the system to respond. Compressor protection feature is engaged. Wait 5 minutes for the system to restart safely, without damage to the compressor (see page 9).

Cool On System

Cool Setting
This feature helps prevent damage to the compressor in your air conditioning or heat pump system. Damage can occur if the compressor is restarted too soon after shutdown.This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the message Cool On or Heat On (heat pumps only) will flash on the display.When the safe wait time has elapsed, the message stops flashing and the compressor turns on.
Message flashes until safe restart time has elapsed
Auxiliary heat control (Setup Function 26)
Systems with heat pumps can be set to operate in one of two ways: Comfort Setting: The thermostat will prioritize comfort over economy depending on heat pump performance, load conditions and whether the equipment is calling for heat. Raising the temperature just a few degrees will often activate auxiliary heat. Economy Setting: The thermostat will attempt to reach the temperature setting without activating auxiliary heat. The thermostat waits a preset time before allowing auxiliary heat to be activated depending on the compressor stage performance, and on how many degrees the temperature setpoint is changed.

In case of difficulty

If you have difficulty with your thermostat, please try the suggestions below. Most problems can be corrected quickly and easily.
Display is blank Check circuit breaker and reset if necessary. Make sure power switch at heating & cooling system is on. Make sure furnace door is closed securely. If thermostat is battery powered, make sure fresh AA alkaline batteries are correctly installed (see page 10).
Temperature settings do not change
Make sure heating and cooling temperatures are set to acceptable ranges: Heat: 40 to 90F (4.5 to 32C). Cool: 50 to 99F (10 to 37C).
Check temperature range stop settings (Function 27 & 28 on page 12). Heating system does not respond (Heat On appears on screen) Check for 24 Vac at the equipment on the secondary side of the transformer between power and common. If voltage is not present, check the heating equipment to find the cause of the problem. Check for 24 Vac between the heat terminal (W) and the transformer common. If 24 Vac is present, the thermostat is functional. Check the heating equipment to find the cause of the problem. Check for loose or broken wires between the thermostat and the heating equipment. Check for 24 Vac at the equipment on the secondary side of the transformer between power and common. If voltage is not present, check the cooling equipment to find the cause of the problem Check for 24 Vac between the cooling terminal (Y) and the transformer common. If 24 Vac is present, the thermostat is functional. Check the cooling system to find the cause of the problem. Check for loose or broken wires between the thermostat and the cooling equipment.
