The CoolAutomation CoolMasterPro (CMPDK000) is the large-site gateway of the CoolMaster line. It connects VRF/VRV systems from all major manufacturers to building management and home automation systems, handling up to 255 connected units across several HVAC lines and brands on a single device.

What sets the Pro apart is local access to VRF service data: outdoor and indoor operating values (pressures, temperatures, compressor and valve data on supported brands) are published over Modbus and BACnet, so the BMS can monitor system performance, not just on/off and setpoints. For direct KNX TP connection, choose the CoolMasterPro KNX.

Key Features

  • Up to 255 connected units (indoor units, CoolPlugs, sensors, fan coils); limits vary by HVAC brand
  • Local access to VRF/VRV service data points over Modbus and BACnet (brand specific)
  • Modbus RTU, Modbus IP, BACnet MS/TP, BACnet IP, ASCII and REST API on one device
  • Universal interface to all major VRF/VRV brands, several lines and brands on one gateway
  • RS232, RS485 and Ethernet interfaces with automatic driver detection for home automation systems
  • Built-in color touch screen for setup, unit discovery and local control
  • Dry-contact GPIO for central all-on/all-off triggering (e.g. fire alarm)
  • Optional CoolAutomation professional cloud apps for remote diagnostics (subscription)

Compatible HVAC Systems

VRF/VRV systems from Daikin, Mitsubishi Electric (City Multi), Fujitsu, Toshiba, Panasonic, Hitachi, Samsung, LG, Gree (GMV5/6), Midea, Haier, Mitsubishi Heavy, TICA, Blue Star, AUX and Chigo. Service data availability is brand specific. Send us your equipment list and we will confirm compatibility before you order.

Typical Applications

Hotels, offices, schools, healthcare and large residences where a BMS needs full VRF control plus performance and fault data for maintenance teams.
