 "summary": "FSL-CONTROL III is the controller of TROX decentralised façade and parapet ventilation units. It runs on a Schneider Electric M172 controller and connects to BACnet MS/TP or BACnet IP through an interface card. The object list has 62 objects: analogue inputs for temperatures, humidity, air quality, flow rates, valve positions and states, analogue/binary/multistate values for BMS presets (operating mode and type, setpoints, fan stage, fire, window, changeover), and multistate inputs for the current state.",

 "notes": [
  "This list is from the 2024 manual (software 8.0). The 2020 manual (A00000080125 V1) numbers many objects differently (for example AI 0 was the supply air temperature), so check the controller software version.",
  "Values written by the BMS are the \"Default\" (fIn/bIn/eIn) objects; the \"Output\" (fOut/bOut/eOut) objects are read-only.",
  "Some states are carried in analogue objects (fan stage, operating state, operating mode override); the codes are listed in the states field.",
  "Temperature defaults of 327.67 and 65535 mean \"not set / invalid\".",
  "The device object reports Schneider Electric (vendor 10), model M172, because the controller hardware is a Schneider M172."
