2pcs W1209 DC 12V Digital Temperature Controller Board Digital Display Thermostat -50-110°C Electronic Temperature Temp Control Module Switch with Waterproof Case

Assembly needed using the provided teeny tiny nuts and bolts to get the case together. After that controller works great. (2) more case I need to assemble. See image.

Ordered to monitor air temperature in a cable headend and it works perfectly so far

These use some junk components... I had to order several packs to actually get the expected quantity of working boards, because about half of them would fry (the microcontroller, I believe) as soon as I connected power. If they happen to make it past the first few minutes of testing, they seem to work fine....Also, these new-style acrylic puzzle piece "cases" are TRASH, FYI. If you look at them wrong, they'll break in 4 places.

I used this thermostat to control a fan to keep my shed from getting too hot. The instructions could be more detailed, but once you figure out how to use the buttons to set the temperature, mode, and hysteresis, it is easy. Some of the 4 little screws that hold the wires were very hard to loosen at first (I almost gave up), but they were fine once I applied enough torque to loosen them. I attached the bottom board to the controller board with the 4 biggest screws (and spacers) provided, but the top board did not have an opening for the LED display, so I didn't attach it, but that's OK since it's not really needed.

That would be nice in the usa.

Beautiful readout. Quality built

lo unico es que no trae manual y tuve que buscar en internet como configurarlo

First, to get this temp control together you have to be an expert at puzzles. Then you have to hope the parts don’t break like mine did while trying to assemble. This is not something I would buy again.
