When scanning the Midea bus, the AC units can be found and read, but every command sent to the unit is reverted.
There's an XYE Extension Kit and a central controller in the system. The central controller is connected to the CTR1 connector, and the Intesis gateway is connected to the CTR2 connector of the XYE Extension Kit.
The Intesis gateway features a built-in resistor that can be enabled using the DIP switch SW B, position 1.
