With its powerful on-board processing capabilities, it reduces dependency on continuous internet connectivity, enabling universal central control, management, and monitoring both locally and remotely.
Whether dealing with a single VRF/VRV system or a complex multi-brand setup, the EDGE provides a complete, robust integration and control solution in one holistic package.
* Access to CoolMaster EDGE’s advanced features requires an active subscription to one of our cloud-based suites

Due to the proprietary nature of VRF/VRV system communication protocols, controller access and BMS integration pose significant challenges that typically necessitate a brand-specific mediation gateway.
CoolMaster EDGE provides a superior solution. It stands out as a universal device with the unique ability to centralize control (locally and/or remotely) of VRF/VRV systems, as well as any other HVAC system/sensor with a BACnet interface.
The EDGE enables seamless cloud connectivity and boasts edge-based smart logic to ensure robust management of energy, IAQ, and HVAC systems.
By leveraging powerful local processing capabilities and a local web-based application, the EDGE simplifies commissioning, allowing integrators to complete tasks on-site. Its intuitive BACnet configuration tool makes it easy to link and map HVAC systems/sensors.
When hooked up to the internet, the EDGE provides access to CoolAutomation’s smart cloud tools, which facilitate remote management, monitoring, and diagnostics of connected HVAC systems.

CoolMaster EDGE is ideal for projects where flexibility, reliability, and local resilience in HVAC system integration are critical, especially at remote or sensitive sites with limited or intermittent internet connectivity. Its smart setup wizard also makes it especially useful when dealing with legacy HVAC systems or if control over complementary BACnet-based devices is required.
Local data buffering ensures that CoolMaster EDGE continues logging and storing HVAC system data even during internet outages. Once connectivity is restored, all data is automatically synchronized with the cloud, ensuring no loss of information for monitoring, diagnostics, or performance analysis.
Yes. While local integration and control are available out of the box, access to CoolAutomation’s advanced cloud-based tools, such as smart monitoring, predictive maintenance, remote management, and analytics, requires a subscription.
Features like local data buffering and edge logic are designed to ensure continuity for cloud-based services during connectivity interruptions. If you’re not using our cloud platform, these resiliency capabilities have limited relevance.
