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.
Temperature buttons Press to adjust temperature settings Hold button Press to override programmed temperature control Function buttons Press to select the function displayed just above each button. (Functions change depending on the task.)
Adaptive Intelligent Recovery (Setup Function 13)
Adaptive Intelligent Recovery eliminates guesswork when setting your schedule. It allows the thermostat 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 thermostat 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.

Battery replacement

Press and pull to remove
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. 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.

Insert fresh AA alkaline batteries, then reinstall battery holder
