CoolMaster - Enable BACnet and Service Data (Diagnostics)

The CoolMaster & CoolMasterPro devices have a few more options built-into their touch-screen menus that the legacy CoolMasterNet device did not have. 

Service data (Diagnostics points on the VRF/VRV units) in these devices is disabled by default. However, you can simply enable them from the touchscreen menu.


To enable Service Data (Diagnostics), you can switch the "Service" toggle in the HVAC line menu.



Both BACnet & Modbus configurations can now be changed and enabled in the BMS settings menu.


It is important to remember to refresh/repopulate the Virtual Addresses Table (VA List) on the controller AFTER a few minutes of the Service data points were enabled.
