CoolMaster Universal HVAC Bridge

A universal solution for VRF HVAC system control and integration with Building Management Systems (BMSs) and home automation. 

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 interface.

CoolMaster gateways are plug-and-play solutions that do not require prior HVAC technical 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.

How It Works

VRF\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 systems requires a brand-specific mediation device, as each manufacturer uses its own communication protocol.

With a CoolMaster, you don’t need to implement a different integration logic or acquire a separate device for systems from different brands. CoolMaster gateways natively connect with systems of all brands and provide a unified interface for integrating HVAC control and monitoring capabilities into your preferred home automation or building management system.

Each CoolMaster creates a bi-directional, universal communication channel between VRF HVAC and automation systems, enabling 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 VRF system management, monitoring, diagnostics, and control.
• Connect VRF HVAC systems to leading smart home platforms (such as Apple Home and Alexa), voice assistants, IoT devices, and smart thermostats.
