 "summary": "Packaged rooftop unit whose MicroTech 4 controller speaks Modbus RTU through a plug-on RS-485 module. Everything is a 16-bit holding register: air and refrigerant temperatures, pressures, capacities, setpoints, occupancy and application-mode commands, network enables, status enums and alarm numbers. Values use English or Metric units per a controller setting.",

  "Network settings (defaults 38400 bps, no parity, 2 stop bits, address 1) come from the companion manual IM 1374-1-1, Modbus RTU Communication Module for MicroTech 4 Rebel and Rebel Applied (Feb 2026): https://tahoeweb.daikinapplied.com/api/general/DownloadDocumentByName/media/IM%201374-1%20MicroTech%20Rebel%20Applied%20Modbus%20Comm%20Manual%200219.pdf",
  "The document marks writable registers 'W' and defines that as read-write; they are listed as RW.",
  "The document never defines 'x 10' / 'x 100' / 'x 1000'. The only reading consistent with its decimal ranges and defaults (for example '72°F x 10', '-45.6-121.1°C x 10') is raw = value x factor, so scales are 0.1 / 0.01 / 0.001.",
  "Units follow register 261 / the module's 'Unit Support' setting (default English). Units shown here are the English ones (°F, psi, in. w.c.); in Metric the same registers carry °C, kPa and Pa with the same multiplier.",
  "Signedness is not stated. A register is INT16 only when its published English or Metric range includes negative values (or an enum uses -1); every other register is UINT16. Each kept register's range was checked to fit its type after scaling in both unit systems.",
  "The network 'invalid' value for space/outdoor temperature inputs is printed as 621.8 °F / 327.7 °C x10; the raw number is not stated.",
  "Left out: every two-register value (energy and power totals 80-115, airflow setpoints 175-176 and 187-190, run-hour counters 191-236) because the document never states the word order for multi-register numbers.",
  "Left out: single-register airflows 29, 30 and 172 ('0-60000 cfm x 10' cannot fit in 16 bits), building static pressure 9 (x10 on a ±0.249 in. range is unclear), return fan DSP setpoint 134, exhaust plenum setpoint 135 and OAT 128 (no multiplier printed), and duplicate/unnamed rows (133, 169, 171, 178, 180, 182, 183, 258, 283-287, 292).",
  "Left out: air-quality sensors 31-38, circuit 3 points 63-73, generic I/O 300-349 (expansion module) and most configuration enums 353-376. Alarm number meanings (pp. 25-37) are not reproduced.",
  "Left out because the '% x 10' multiplier cannot be trusted: this revision shows a mechanical '%' -> '% x 10' edit (register 15 reads '0-100% x 10 x 10', notes read '100% x 10 outdoor air' and 'held at 0% x 10', an alarm text reads '5% x 10' and the ASCII appendix lists '% x 10' for character 37). Every percent register is therefore ambiguous between raw 0-100 and 0-1000: 10, 11, 15, 18, 25, 27, 125, 126, 144, 145, 149-153, 163, 165, 167, 168, 174 and 186.",
  "Left out: maximum purge time 184 ('0-300 Min x 10'), because the same edit also produced 'Min x 10' text (Unit State value 4 reads 'Min x 10DAT').",
  "Left out: filter pressure 21 (the table cell spans registers 21-23, and '0-1250 Pa x 100' cannot fit 16 bits in Metric) and building static pressure setpoint 137 ('-62.2-62.2 Pa x 1000' cannot fit a signed 16-bit register in Metric). Also not mapped: exhaust air plenum static pressure 24 and Remote Setpoint Source 270/271, power monitor reset 272.",
  "Unit State (260) value 4 is printed 'Min x 10DAT', an artefact of the same edit; it is listed with the printed text.",
  "The data-bits setting is not stated in ED 19133-2 or IM 1374-1, so it is left null."

  "watchdog": "The module's Com LED Timeout (0-3600 s, default 3 s) only turns the bus LED red when the client stops polling; no control fallback on comms loss is documented. Network temperature/RH inputs fall back to local sensors when the network value is unreliable.",
