When you are in Auto Change Over mode, the display will say either “auto heat” or “auto cool” to the left of the room temperature. If you are trying to change the heat setting when the display says “auto heat”, or trying to change the cool setting when it says “auto cool”, simply press the + or – button. If you want to change the cool set point when it says “auto heat”, you must first press the mode button until the mode shows “cool”, then use the + or – to change the cool set point. Then press the mode button to switch the mode back to Auto Changeover. If you want to change the heat set point when it says “auto cool, you must first press the mode button until the mode shows “heat”, then use the + or – to change the heat set-point. Then press the mode button to switch the mode back to Auto Changeover. If you are trying to set the heat and cool set points for your program settings (wake, leave, return, sleep) the thermostat allows you to adjust each set point as you cycle through the program settings.
