LED button. Press the LED button to turn on the
indoor unit display (on units with display). Press the

remote's air temperature sensor. This will also transfer
the temperature sensing function from the indoor unit
to the remote. The indoor unit's air temperature sensor
will be disabled. The indoor unit will regulate the room
temperature based on the temperature sensor in the
remote controller, rather than the sensor in the indoor
unit.
The remote controller will send the indoor unit a signal
every three minutes. If the indoor unit doesn't receive
the signal for seven minutes, or if the button is pressed
again, the Follow Me function will terminate.
The remote controller must remain pointed toward the
indoor unit and must be within 26 feet (8 meters) of
the unit. Do not remove the controller from the room
or obstruct the signal of the remote controller during
