How it works

VRF and VRV systems design is a closed communication loop between the condensers and evaporators. These communication loops vary from one manufacturer brand to another. Traditionally, controlling and integrating these VRF HVAC systems 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 a separate mediation device for each brand, or to implement a different logic of integration with each of them separately. CoolMaster connects with all brands and provides a universal unified interface for integrating control and monitoring capabilities to your preferred Home Automation or Building Management System.

CoolMaster enables a bi-directional universal communication channel between the VRF HVAC and the automation systems, that enables Automation integrators and HVAC Professionals to:

  • Natively integrate Home and Building Automation Systems with VRF HVAC
  • Connect with the CoolAutomation’s application suite which includes capabilities for Facilities Management, Monitoring, Servicing, and Control of the VRF systems.
  • Connect VRF HVAC systems leading Smart Home Devices, such as Google Home, and Amazon Alexa voice assistant, iot devices and smart thermostats.
