How to set the mode for Orange Hotel air conditioner

The specific operation of the Orange Hotel air conditioning setting mode:

1. In the shutdown state, press and hold the mode button for 5 seconds. There will be a beep and the main icon in the lower right corner will light up.

2. The internal unit corresponding to the wire controller becomes the master internal unit, and the original master internal unit becomes the slave internal unit. Only the master internal unit is changed to the heating mode first, and the other internal units are changed to the heating mode first. Only an internal unit can be used, mainly to avoid mode conflicts. Some people turn on cooling and some turn on heating.
