How do I turn on the ComfortSense feature?

Point the remote control towards the unit and press the ComfortSense button. The remote's display will show the actual temperature at its location. The remote must be within 26 feet of the air conditioner to work, and it will send this signal to the unit every 3 minutes until you press the ComfortSense button again. If the unit does not receive the signal during any 7 minute interval, the unit will beep to indicate ComfortSense mode has ended.
