The digital screen, the top row of lights don’t work in all four digits. And of course since it’s from China the instructions are hard to understand and are missing some info I think.

long press "set" p0(+/-)to cooling or heating(c or h). in normal temperature reading mode, short press set(numbers will blink) this is the temperature that will start your cooling or heating apparatus. e. g. your room is 50deg and you want to run a heater to 60deg: the temp is reading 50; press "set" screen flashes a number; you press +/- until 60, then wait until accepted. relay will turn on until 60 deg then turn off and repeat. and vice versa for cooling.

These use a stm8s003f3 microcontroller, and seem to be pretty accurate, as in dead on as they come from the factory with the supplied NTC. My use is to control heaters on RV tanks. I replaced the 10K, B3950 NTC with this 9' one https://www.amazon.com/gp/product/B01MZ6Y336.You will need to re-calibrate, which I did by placing ice in a plastic bowl with water. Use P02 to adjust the temperature until it reads 32 degrees. They hold their settings after power off. Well worth the money.

I really like the fact that this module is available as a 5 volt unit that works with USB devices. I'm using it to control a small air circulation fan inside an RV refrigerator. Since the module itself is an unprotected circuit board (no case), I was glad that it came in an anti-static plastic pouch so I could keep it protected from condensation that inevitably occurs in a refrigerated environment. The module is easily programmable (though there is some vagueness in the written instructions), works well, and is reliable thus far. And, at $6.99, it's really inexpensive.

Great little controller, heat cool settings. Temp probe could be longer and deg F. There are upgraded models for this. Will buy again.
