CoolPlug RS232, RS485, IP Interface – Wireless


Additional information


CoolPlug is a hardware device which, along with CooLinkHub, enables the integration of Split, Multi-Split, or Mini-Split HVAC systems with Home Automation, Building Management Systems, and Cloud Control Applications.

CoolPlug and CooLinkHub work together to create a universal communication channel which enables split HVACs to work with a wide range of automation systems.

CoolPlug provides automation integrators, facility managers, service providers, and HVAC professionals with the ability to remotely control, monitor, service, and manage compatible Split, Multi-Split, or Mini-Split HVAC systems through the creation of a bi-directional and universal communication channel between the HVAC and automation systems.

CoolPlug is a plug & play device. The integration and installation process is simple, seamless, and straight-forward, and can be synced with CooLinkHub via a wired or wireless connection.

CoolPlug’s wireless capabilities are ideal for retro-fit projects, as it eliminates the need for drilling or opening up walls and ceilings.

CoolPlug provides access to the complete CoolAutomation suite of applications, along with compatibility with independently developed applications through a proprietary API.


Split HVAC systems utilize a communication port to connect the indoor and outdoor units, in order to control and receive feedback from the HVAC system.

When CoolPlug is synced with CooLinkHub, and connected to the indoor unit, it gains access to the entire system, and enables integration of the connected unit with Home Automation, Building Management systems, or Cloud-Based Applications.

Multiple CoolPlugs can be connected to a single CooLinkHub in order to enable control over multiple Split HVAC indoor units.
