4.2.4 MAIN / SUB Setting when Using Two Remote Controllers
Situation
The MAIN / SUB setting is necessary when one indoor unit is controlled by two remote
controllers. When you use two remote controllers (control panel and separate remote
controller), set one to MAIN and the other to SUB. You can do this by setting the switch on the
remote controller’s PCB.
Setting
The remote controllers are factory set to MAIN, so you only have to change one remote
controller from MAIN to SUB. To change a remote controller from MAIN to SUB, proceed as
follows:
