CoolMaster 9000H is a control adapter connecting Hitachi VRF Air Conditioning systems with any RS232 or USB featured devices (e.g. home PCs, embedded PCs or Home Automation controllers).
Connecting the CoolMaster 9000H with such controllers through common RS232 or USB provides end-users with full control of all Hitachi VRF indoor units enabling them with access to HVAC various functionalities.
When utilising CoolMaster 9000H Home Automation integrators and HVAC installers will not have to worry anymore about the complexity involved in understanding and working with Hitachi internal communication line and gateways including their unique physical layer.
With CoolMaster 9000H, Hitachi vrf integrators will be provided only with a simple, well documented open ASCII protocol over RS232 or USB to seamlessly integrate with any Home Automation application.
Seamless easy integration with Home Automation systems and PC’s applications
Interfacing Home Automation controllers with CoolMaster 9000H is a simple and straightforward 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 VRF system is connected via CoolMaster 9000H, will function exactly the same way for Mitsubishi Electric VRF, Sanyo VRF, Toshiba VRF etc. No special interface adaptation is required to migrate from one CoolMaster type to another.
Full Control over Indoor Units Operation
On/Off control, Cool, Heat, Fan, Dry mode selection, Set Temperature control, Fan Speed control, Swing control (for wall mounted and cassette indoor units), Filter reset sign, Group operations (All On, All Off).
Outdoor Units internal parameters: Condensing, Evaporation, Ambient Temperatures, EV Opening, System Power Consumption (current), Inverter Revolutions and others Indoor Units internal parameters: Return air, Gas and Liquid Temperatures, EV Opening. Those features are currently available for Daikin VRV, Mitsubishi Electric and Hitachi VRF air conditioning systems.
Indoor Units Monitoring
Failure Alarms, Set point temperature, Operation status (on/off) Operation mode (cool/heat/fan/dry), Fan speed (high/low), Filter sign, Swing.
New Firmware can be uploaded via RS232 port. No need to open unit to change it’s functionality.
