You can select heating or AC any time by positioning the controls ( and setting the fan to auto ). The unit will automatically shut off if the door is open and there is no movement in your room . The door to each room must be closed in order to maintain your thermostat setting .
* If the AC is not working properly , shut off the HP switch , wait 5 minutes and turn it back on . Allow 30 minutes to see if the unit is working correctly .
