CoolMaster Product Line
The CoolMaster Product Line allows home automation specialists, building automation integrators, facility managers and HVAC professionals to integrate, control, remotely monitor, service and manage any VRF or VRV HVAC system through a single device.

CoolMaster gateways are plug-and-play solutions that do not require any prior technical HVAC knowledge to install. Simply unbox, ensure the device is configured to the right HVAC brand using the built-in display, connect as indicated, and... that’s it.

The product line includes two devices:

CoolMaster fits most residential and small-medium commercial settings where the number of indoor units is limited.

CoolMasterPro is designed for large commercial facilities that not only have numerous indoor units connected, but also require local access to technical and operational data for building or facility management solutions.

CoolMasterNet has been discontinued and replaced by the CoolMaster Product Line, offering enhanced features and capabilities.

How it works

VRF and VRV systems are designed with a closed communication loop between condensers and evaporators. These communication loops vary from one manufacturer brand to another. Traditionally, controlling and integrating VRF HVAC system controls requires the mediation of a brand-specific interface device, as each manufacturer utilizes its own unique communication protocol.

With CoolMaster, you don’t need to implement a different integration logic or a separate mediation device for each brand. CoolMaster connects with all brands and provides a universal unified interface for integrating HVAC control and monitoring capabilities into your preferred home automation or building management system.

CoolMaster creates a bi-directional, universal communication channel between VRF HVAC and automation systems, enabling automation integrators and HVAC professionals to:

  • Perform native VRF HVAC integration with home and building automation systems
  • Use CoolAutomation’s application suites, which include tools for facility management, monitoring, servicing, and control of the VRF systems.
  • Connect VRF HVAC systems to leading smart home devices (such as Google Home and Amazon’s Alexa), voice assistants, IoT devices, and smart thermostats.
