Operating Manual Adaptive Intelligent Recovery (AIR) TM 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. 4 PRO TH40D / TH420D Built-in compressor protection 75 Wake Wed Inside 6:30 AM 75 Cool On Set To 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 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). When the safe wait time has elapsed, the message stops flashing and the compressor turns on. Message flashes until safe restart time has elapsed. Operating Manual Battery replacement About your new thermostat Pull at bottom to remove thermostat from wallplate.
