Normal Operation 72 MODE SWITCH Heat, Cool or Off UP & DOWN BUTTONS FAN SWITCH On or Auto Manual Operation Select heat or cool with the mode switch. Normally leave the fan switched to auto. In fan auto, the fan will turn on only with a heat or cool demand. When Fan On is selected, the fan will run continuously, even when the mode switch is set to Off. Adjust the desired set temperature with the Up or Down buttons.
Step #1 72 Heat Off Cool Fan On FanAuto Proper installation of the thermostat will be accomplished by following these step by step instructions. If you are unsure about any of these steps, call a qualified technician for assistance.
