Setting the main and sub remote controllers
1. Set one of the 2 connected remote controllers as the main remote controller.
2. On the other remote controller (sub-remote controller), switch the remote controller address connector on
the rear of the remote controller PCB from Main to Sub. When the connector has been switched, the remote
controller will function as the sub-remote controller.
