This is achieved through reliable bi-directional communication with automation systems.
CoolPlug is a plug-and-play device with a simple installation process. It can use both wired and wireless interfaces to connect with CooLinkHub, which then seamlessly integrates with your chosen control/automation platform via industry-standard communication protocols.
The wireless option is ideal for retrofit projects, as it eliminates the need to open walls or ceilings.
CoolPlug and CooLinkHub provide access to all of CoolAutomation’s application suites and also support independently developed applications through a proprietary CoolAutomation API.

Split HVAC systems utilize a communication port to connect indoor and outdoor units. This interface enables effective control and proper operation.
When CoolPlugs are connected to each indoor unit’s port and then sync with a CooLinkHub, they create a single access point to the entire system. This facilitates the integration of connected units with home automation and building management systems, as well as cloud-based applications.
Up to 10 CoolPlugs can be connected to a single CooLinkHub, enabling seamless control of multiple split HVAC indoor units.
