 "summary": "The UC-3 is the unit controller on AbsolutAire heating and ventilating units. It joins a BACnet MS/TP network with a device instance built from its DIP-switch MAC address. The BMS writes network_ values for on/off, occupancy, setpoints, economizer and sensor overrides, and reads temperatures, commands, fan/burner status and alarm objects. The IC-3 user guide prints the identical points table.",
