CoolAutomation - Gateway for connecting up to 10 CoolPlug

The CoolPlugs & CooLinkHub solution allows seamless integration of Split, Multi-Split, and Mini-Split HVAC units with home automation, BMS, and Smart IOT products and services; or complete control and monitoring using a standalone CoolAutomation cloud application (ControlApp).

Once connected, it allows full control of the indoor unit including the following functions: on/off, operating mode (cooling/heating/fan/dry/auto), set points, fan speed adjustment, and swing activation.

The solution enables bidirectional communication with the indoor unit to receive error codes from the unit as well as feedback on the actual state of the HVAC unit. CoolPlug connects directly to the indoor HVAC unit at one end and to the CooLinkHub at the other.

CooLinkHub - groups multiple CoolPlug devices and provides extensive interface options for controlling and monitoring each of the CoolPlugs, either via the wired network (PBUS) or on a proprietary wireless mesh network.

CooLinkHub gateway functions:

• Seamless integration of VRF and Split indoor units (connected to CoolPlug) with home automation/BMS controllers
