Delta DTM temperature controller

Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.

coherence-checked

Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

link settings as documented (unverified): RTU/ASCII/TCP; default 38400 8E1; unit ID 1; FC 03,06,16; Supports RS485, Ethernet (Modbus TCP), and USB (for configuration only, no signal isolation).

⚠ USB connection has no signal isolation and cannot be used for long-term monitoring. — Starkest reads only; we never write a control register.

bench facts as documented (unverified)

terminals	RS485 communications terminal, Power input terminal, Sensor input terminal
connector	RJ-45, Mini USB, RS485 terminal
isolation	Channels are completely isolated from each other. USB has no signal isolation.
wiring notes	Requires needle-type terminals with diameter < 2.35mm.
max registers/read	64
protocol notes	Initialization takes approximately 30 seconds after power on, during which external communications are unavailable.
identification notes	Model and serial registers not explicitly defined in the provided pages.
power	24V DC (90% ~ 110% of rated voltage). Host Max 6W + 5W * measurement modules + 3W * I/O modules.
environment	Operating temperature: 0°C to +50°C. Storage temperature: -20°C to +65°C. Operating humidity: 35% to 85% RH (no dew). Operating altitude: Below 2,000 meters. Pollution level: 2.
accuracy	Sampling frequency: 0.1 sec./all 8 inputs.
doc revision	V1.0 (2020/02/22)

⚠ disputed: default_unit_id: 1 — disputed by DTM Software Operating Manual v1.3, which states that when the host station number dial switch is set to 0 (the default 'All OFF' setting), the RS-485 station number address is 16 (DEC) / 10 (HEX).

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.
coherence-checked — Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.
hardware-verified (software-key) x1 — Matched a real device with operator-attested readings as ground truth — the only rung that confirms word order + scaling on the wire.
