The two relay temperatures came back as 331 and 319 from a charger sitting idle
with nothing plugged in. The spec's gain column says 1 for both, so we reported
them as 331 °C and 319 °C — a reading that would have meant a fire rather than a
wallbox at room temperature.
The gain is 10. The same table hands the maximum current setting a unit of watts
and the timeout a unit of amps, so its unit and gain columns are not load-bearing
here; what settles the alignment is the LED brightness two registers earlier,
which reads exactly 100 at gain 1, and the fact that the neighbouring registers
all decode as tabulated. Read back from the charger afterwards: 33.1 °C and
31.9 °C.
The field becomes a float, as the voltages and currents beside it already are.
