Indoor units are controlled by a wireless remote control.


  • Each indoor unit comes with a wireless remote control and is used to make any changes to unit settings.
  • The remote does not sense the room temperature (like other units). The sensor is inside the indoor unit.
  • Remote comes with a wall mount but can be kept anywhere.
  • Remote must be used within 20 ft of unit to be sure the unit receives the signal.
  • Remotes are not specific to a certain indoor unit. The remote for one indoor unit will control another indoor unit.
  • The remote uses standard infrared, much like a TV remote.

If the remote control is not working or only works intermittently:


  • Make sure the unit beeps or flashes every time a change is made. If the unit does not beep or flash, it did not receive the command.
  • The distance from the remote control to the receiver should be no more than 23 feet (20 is preferred) with no obstructions, like furniture, curtains, lamps, etc.
  • Remote control malfunctions can sometimes be corrected by removing the batteries from the remote for a few minutes and then reinstalling them. If the remote control display is weak or the operating distance has lessened, the batteries may need to be replaced.

To check or replace the batteries:

  1. Remove the battery cover
  2. Insert 2 AAA batteries as illustrated noting battery polarity
  3. Reinstall the battery cover.
  4. If any segments of the display remain active after battery removal, press the reset button on the remote.


Note:  Remove the batteries from the remote control if the unit will not be in use for an extended period of time.
