    "All registers are holding registers. The document numbers them from 1 and calls the type Holding Register (40.000), so the addresses are 1-based (address on the wire = number minus 1). The document does not say so explicitly: if a read fails, try address_base 0.",
    "The document allows 2400 to 57600 bps with automatic baud rate detection, 8 data bits, 1 stop bit and no, even or odd parity. It gives no default baud rate or slave address: 9600 N and 1 are placeholders. Register 92 holds the parity setting.",
    "Temperatures have the scale -1000:10 in the document. It is read here as: value = raw / 10 - 100, which fits the stated range of -50.0 to 250.0 with raw values from 500 to 3500. This reading is not confirmed by the document: check one value against the display.",
    "Other scales in the document are written as 1:N and are read as raw / N. Registers whose scale column is unclear are given as raw values.",
    "The document names the alarm temperatures of registers 2 to 4 'sensor 1 to 3' and the shutdown and fan temperatures 'winding 1 to 3'; the names here follow the document.",
    "Registers 15, 20, 46, 47, 49 are not in the document. Registers 76, 101, 108 to 118 and 140 to 149 are left out because their descriptions in the document are repeated, garbled or inconsistent.",
    "Registers 5, 10, 45, 48, 50, 52, 75 and 79 are bit fields, one entry per bit. The command bits of register 45 are write-only.",
