2.8 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:
Step Action
1 Insert a flathead screwdriver into the recess 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 Turn the MAIN/SUB changeover switch on the PCB to “S”.
