Control and Monitor Hitachi VRF Air Conditioning Systems
CoolMaster 9000H is a versatile seamless control adapter connecting Hitachi VRF Air Conditioning systems with any RS232 or USB featured devices like Home PCs, Embedded PCs or Home Automation Controllers.
Connecting such Controllers through common RS232 or USB interfaces with the CoolMaster 9000H will provide end-users with full control of all Hitachi's VRF indoor units enabling them with access to HVAC's various functionalities including diagnostic.
Home Automation Integrators and HVAC installers when utilizing CoolMaster 9000H will not have to worry anymore about the complexity involved in understanding and working with Hitachi's internal Communication line and gateways including their unique physical layer.
Now, with the CoolMaster 9000H, Hitachi's integrators will be provided only with a simple, well documented open ASCII protocol over RS232 or USB to seamlessly integrate with any Home Automation applications.
Seamless easy integration with Home Automation Systems and PC's applications
Interfacing Home Automation Controllers with CoolMaster 9000H is a simple and straight forward process requiring only common ASCII commands over RS232 communication line.
Same RS232 Interface for all VRV/VRF HVAC Systems
All CoolMaster models provide the same RS232 interface for all VRV/VRF HVAC Systems. So for instance, a home automation application, where a Hitachi's VRF system is connected via CoolMaster 9000H, will function exactly the same way for Toshiba VRF, Daikin VRV, Sanyo VRF etc', when using CoolMaster models: 3000T 1000D, 2000S, respectively. No special interface adaptation will be required to migrate from one CoolMaster type to another.
