The inscrutable thermostat (AKA: WH7016 Ultimate) arrived today. It only took 11 days, but it feels like that many months.

I Googled the model number and
found instructions in English that appear to jive.
So I have learned that the unit is intended for Peltier Junction control (may be a problem), uses a Sensor NTC 10K / 3435 thermister for the temperature sensor, and that the display is only in Celsius (not a deal breaker) and that there is a menu system that must be used to enter the desired set-point, and upper limit set-point, and lower limit set-point, and upper-limit alarm, and lower limit alarm, and hysterisis.
Sounds interesting so far. Could turn out to be a Chinese puzzle.
More later.
