Abstract
In one embodiment a control unit for managing an HVAC system includes an RS-BUS interface that may communicate with one or more HVAC units. A plurality of universal asynchronous receiver/transmitter (UART) ports, wherein at least one of the UART ports may communicate with an interactive display using an RS-485 communication protocol, A secure digital input output (SDIO) port configured to interface with a Wi-Fi module, wherein the Wi-Fi module is operable to communicate with a plurality of HVAC sensors, wherein the plurality of HVAC sensors operable to measure temperature. A processor that may receive, from the SDIO port, a sensor reading from one of the plurality of HVAC sensors, the sensor reading formatted according to an 802.11 Wi-Fi protocol. The processor may then convert the sensor reading from the 802.11 Wi-Fi protocol into an RS-BUS protocol, the RS-BUS protocol may control the one or more HVAC units. The processor may also convert the sensor reading from the 802.11 Wi-Fi protocol into the RS-485 communication protocol that may communicate with the interactive display. The processor may then transmit the sensor reading in the RS-485 communication protocol to the interactiv…
