Its fixed BACnet MS/TP map covers airflow and damper control, zone setpoints for up to three zones, humidity, CO2 and dewpoint/condensation logic, five auxiliary outputs, PID loops and configuration multi-states.",

  "The four binary outputs are printed as AO 3-AO 6 (named BO_1-BO_4); AO 4 is printed as \"A04\".",
  "Some MSV state lists are printed in short form (for example \"AI-1, AI-2, AI-3 or AI-4\"); those are kept as printed rather than numbered.",
  "BV 3 OccSched is tagged \"Clg\" in the guide (likely Cfg); treated as writable.",
  "PID loop objects LOOP0-LOOP9 are listed as LO with their printed action and default gains.",
  "Temperature units are listed as °F; the guide prints °F and °C ranges and the controller can be set to metric."
