 "summary": "The TC-3 is a smaller unit controller for AbsolutAire heating and ventilating units with burner control, OA/RA dampers and optional 0-10 V setpoint input. It joins a BACnet MS/TP network with a device instance built from its DIP-switch MAC address. The BMS writes network unit and burner enables, occupancy, heat setpoints and an optional network space temperature, and reads temperatures, burner command and sensor alarms.",
