Easy to integrate with Home Automation Systems and PC applications
CoolMaster Interface is very simple and straightforward. Implementation of software modules to   support CoolMaster is not complex at all.
 

Unified RS232 Interface
All CoolMaster products impose unified RS232 interface. It means for example that home automation application working on Daikin VRV system with CoolMaster 1000D will work exactly the same way on Sanyo VRF system with CoolMaster 2000S and no special interface adaptation will be required to migrate from one CoolMaster type to another.
