Connecting to Midea VRF system
- If CoolMasterNet is the only central controller in the system:
Outdoor Switch SW3-1 must be ON for proper operation of CoolMasterNet connected to XYE bus.
- If two central controllers should be connected:
We recommend to connect to line L7 on CoolMasterNet. Lines L4, L5, L6 can also be used.
Auto Addressing Mode
For proper operation of the Central Controller (CoolMasterNet), it is important to have an Auto Addressing Mode turned ON on Outdoor PCB. This is done by setting S6 (on some models it is called NI_SD-AD_FD) DIP Switches to OFF-OFF-OFF positions like shown on the below picture. After that setting is done it is required to power reset the Outdoor unit.
