 "summary": "The UC-3 HTLV is AbsolutAire's controller for heat-and-vent make-up air units: it runs the burner to hold a discharge or space temperature, with occupied/unoccupied setpoints, a low-temperature limit and a mild-weather heat lockout. It joins a BACnet MS/TP network with the MAC address set on DIP switches. The BMS enables the unit through NetworkUnitEnable, sets occupancy and vent/heat mode, and writes the space and discharge setpoints.",

  "The table also lists the controller's physical I/O as 'Hardware Input n' / 'Hardware Output n' (24 rows) without a BACnet object type; they are left out. The guide marks the outputs do-not-write.",
  "For most multistate objects the guide gives only the enumeration names (e.g. ALARM / NORMAL), not the state numbers; NetworkUnitEnable, NetworkOccupancy and HVAC_Mode numbers are printed in the guide.",
  "Several AV/BV objects are marked [DO NOT WRITE] configuration values.",
  "Sensor alarm MVs use the controller's SensorReliability enumeration, which the guide does not list."
