How It Works

VRF and VRV systems are designed with a closed communication loop between condensers and evaporators, which varies from one manufacturer brand to another. Traditionally, controlling and integrating VRF HVAC systems requires a brand-specific interface device, as each manufacturer uses its own communication protocol.

With CoolMasterLT, you don’t need to implement a different integration logic or a separate mediation device for each brand. CoolMasterLT 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.

CoolMasterLT 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 facility management, monitoring, servicing, and control of the VRF systems.
Connect VRF HVAC systems to leading smart home devices and voice assistants (such as Google Home, Josh.ai, and Alexa), as well as smart thermostats.
Configure automatic changeovers and dual setpoints for any VRF system using cloud-based tools: regardless of brand.
