 "summary": "The UC-3 Lite is AbsolutAire's simpler heat-and-vent unit controller, running the burner to a space or discharge temperature with optional VFD and mixed-air damper. It joins a BACnet MS/TP network with its MAC address set on DIP switches. The BMS turns the unit off, on or to auto with network_UnitEnableCommand, sets occupancy, mode and heat setpoints, and can send its own space temperature.",
