Note: The Auto system setting may not appear, depending on how your thermostat was installed.

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 Comfort Control automatically selects heating or cooling depending on the indoor temperature.
Heat and cool settings must be at least 3 degrees apart. The Comfort Control 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.

Message flashes until safe restart time has elapsed

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.

69-1831--04

Adaptive Intelligent Recovery (AIR)
Adaptive Intelligent Recovery eliminates guesswork when setting your schedule. It allows the Comfort Control to "learn" how long your furnace and air conditioner take to reach the temperature you want.
Just set your program schedule to the time you want the house to reach your desired temperature. The Comfort Control then turns on the heating or cooling at just the right time to reach your scheduled temperature at your scheduled time.
For example: Set the Wake time to 6 am and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.

Note: When Adaptive Intelligent Recovery is in effect, the thermostat will display "In Recovery".

Battery Replacement
Press and pull to remove
Replace Battery

Insert fresh AA alkaline batteries, then reinstall battery holder.

M28620

M28615

Batteries are optional (to provide backup power) if your Comfort Control 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.
If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory, and do not require battery power.
