Up to two remote controllers can be used for each indoor
unit (or each group of indoor units).

method is to take a remote control connection wire
(3-strand) from the indoor unit for the secondary
remote control. The other method is to use a jumper
wire from the main remote control.
2) Set the remote control switch for the secondary unit (SW4) to
secondary unit. (It was set to main unit a the factory.)
Note (1) The remote controller sensor setting is only enabled on the main remote controller.
Be sure to position the main remote controller in a location where it can detect
the room temperature.
