Great Spaces From Concept to Creation
Home Automation bridge for the integration of VRV / VRF Air Conditioning systems

CoolMasterNet is a unique hardware solution for seamless integration of the advanced VRF / Split Air Conditioning Systems and Home Automation / BMS Controllers. Interfacing major Home Automation controllers e.g Control4, Crestron, AMX, RTI, Savant, Vantage and others , through CoolMasterNet’s built in RS232, RS485 and Ethernet communication ports, will provide home end users with full control and monitoring of Air Conditioning indoor units e.g Daikin, Mitsubishi, Toshiba, Fujitsu, LG, Hitachi, Gree and others. Air Conditioning control will now be implemented from same Home Automation controller of which other tasks like lighting, shades, security and similar are controlled. It will also enable HVAC Service Providers to access HVAC’s most essential parameters required for diagnostic and service purposes.

Easy Integration

Home Automation integrators and HVAC installers when integrating CoolMasterNet will not have to worry anymore when connecting to those advanced HVACs and hassle with their complicated communication protocols. Integration and installation process will be straight-forward since CoolMasterNet is a plug & play solution.

CoolRemote – HVAC Remote Access

Connecting CoolMasterNet to the Internet as a standalone device will enable end users and HVAC Service Providers when using mobile phones, tablets or PCs to remotely access and control those advanced VRV / Splits HVACs via Coolremote (coolremote.net), Cool Automation’s cloud based solution.
