Reznor CLIMANAGER packaged AC controller

Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire. Word order and scaling are confirmed at the hardware-verified rung and at no rung below it.

interop-verified

Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

field reports — community-sourced, unverified (checked 2026-06-11)

confirmed: comms defaults (baud rate 9600, parity None, stop bits 1) — confirmed by Gfc23 parameter settings in the MR_KCR_1602A_EN_EU manual [21.4.1]
confirmed: framing (RTU and TCP) — confirmed by Section 10/11 of the MR_KCR_1602A_EN_EU manual stating support for RS485 (RTU) and Ethernet (TCP/IP) platforms
confirmed: facts (doc_revision MR_KCR_1602A_EN_EU, environment -10ºC/+60°C, power 230 Vac) — confirmed by the main specifications of the electronic board on Page 4 of the manual
confirmed: register map summary (0-based addresses) — confirmed by the BMS variables tables in Section 9 of the manual, where analog variables start at BMS address 1 (0-based address 0) and integer variables have a +208 offset (e.g., air_quality_co2_sensor at BMS address 1 + 208 = 209, which is 0-based address 208)

The trust ladder

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.

generated — A prompt produced it. Unproven — anyone can regenerate this.
structure-verified — Decode path is structurally sound (addresses, widths, finite values). Does NOT prove word order or scaling.
interop-verified — Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.
simulator-verified — Decoded correctly against a protocol emulator seeded with known-true values — catches word-order/scaling errors vs the emulator, not the physical device.
hardware-verified x1 — Matched a real device with operator-attested readings as ground truth — the only rung that confirms word order + scaling on the wire.

If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.

To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.

Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
