The integration is based on the CoolMasterNet from CoolAutomation which allows the control of multiple indoor units from outdoor units over Modbus IP. Control over Modbus RTU is also possible however, this would require the addition of a Loxone Modbus Extension.

Integration into Loxone Config

As the CoolMasterNET is capable of controlling multiple indoor units, to be able to offer a control mechanism over Modbus it assigns a Virtual Address to each indoor unit and then uses this address as the base address for the Modbus register of that unit. The Coolmaster is capable of auto scanning a particular line and detecting all indoor units connected to it.
