 "summary": "The Regin Corrigo is a pre-programmed air handling unit controller whose ventilation application is reachable over EXOline, Modbus and BACnet. As a Modbus slave it publishes temperatures, pressures, flows and humidity as input registers, setpoints and manual/auto modes as holding registers, and alarm and I/O states as discrete inputs. Every value is a single 16-bit register; real values are sent multiplied by 10, except air flow (factor 1) and time settings (factor 100).",

  "note": "The 3.6 list prints Modicon reference numbers (00001 coils, 10001 discrete inputs, 30001 input registers, 40001 holding registers), and every table starts at 1; the older 3.2 list prints the same points as bare numbers starting at 1 (e.g. 9 for 30009). We apply the standard Modicon rule (subtract the table base and 1), so Outdoor temperature 30001 is input register 0 on the wire. The manual never states the offset in words; the only worked example is a test-tool screenshot that reads AO1 (30054) by entering point address 54, which matches a tool that numbers points from 1. Confirm on site by reading the outdoor or supply temperature."

 "notes": [
  "Scaling: the manual says Real (R) signals are multiplied by 10, time-setting signals by 100 and air flow signals by 1; Integer, Index and Logic signals are not scaled. Scale 0.1 is applied to every Real register here except the air flows.",
  "Signedness is not stated per register. Real and Integer values are listed as INT16 because temperatures and offsets can be negative; Index (enumeration) values are UINT16. A x10 value in INT16 cannot exceed 3276.7, so very high pressures or CO2 readings may not fit.",
  "Extract/exhaust naming is swapped inside the controller: 30009 (variable ExhaustAirTemp) is extract air from the room, and 30020 (variable ExtractAirTemp) is exhaust air leaving the unit. Names here follow the measured air, as the manual's own notes do.",
  "Enumerations are the Modbus values. The same points over BACnet start at 1 instead of 0 (e.g. run state Stopped is 0 on Modbus, 1 on BACnet).",
  "Left out: the per-alarm status registers (30071 onward). In the 3.6 list the value legend (0 Not used, 1 Normal, 2 Blocked, 3 Acknowledge) is printed in the rows of alarms 2-5, which hides those alarms' names, and the full legend only appears in the older 3.2 list. Use the alarm discrete inputs (10033 onward, 0 = no alarm, 1 = alarm) instead.",
  "Left out: fan running-hour counters (30004/30005) and accumulated fan energy (30275/30279), because a x10 16-bit value overflows quickly and the manual gives no rollover or energy unit.",
  "Left out: weekly schedules (40040-40263, HH.MM x100), holiday dates, PID tuning, alarm delays, I/O assignment indexes, expansion-unit I/O, the real-time clock and the slave-drive tables in chapter 7.",
  "Printing errors in the source: the UAI3 and DO3 assignment registers are printed as 3040 and 3066 instead of 30040 and 30066 (neither is included here).",
  "Transport: the manual describes RTU framing only. It names Modbus TCP just as one possible physical layer in a general paragraph, so TCP is not listed here.",
  "Terminology: the manual's introduction defines 'exhaust' and 'extract' the opposite way round from the register descriptions; the descriptions here follow the register rows and the 3.2 list, where point 9 is the extract (room return) air and point 20 the exhaust air."
