4.2.3 MAIN / SUB Setting when Using 2 Wired Remote Controllers
Outline The MAIN / SUB setting is necessary when 1 indoor unit is controlled by 2 remote controllers.
When you use 2 remote controllers (control panel and separate remote controller), set one to
MAIN and the other to SUB.
Detail The remote controllers are factory set to MAIN, so you only have to change one remote
controller from MAIN to SUB.
Step Action
1 Insert a flat screwdriver into the groove between the upper and lower part of the
remote controller, as shown in the illustration below. Gently pry off the upper part
of the controller, working from the two possible positions.
2 Set the [MAIN / SUB changeover] switch on the PCB to “S”.
