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.

The boards seem to work fine but the cases seem to have a problem. I bought a 3 pack. The first one I assembled I tightened down the bolts on the case firmly. Within a few minutes the bottom of the case had cracked in several places. So, when I assembled the other two I was really careful to not over tighten any of the 8 bolts on each case. I used a small screw driver and only held the tiny nuts with my fingers and then only just snugged up the screws. They looked fine but after they sat for an hour or so they both developed cracks in the bottom. As more time has passed they have continued to crack more until they have become useless. I do find it interesting that only the bottoms crack, not the tops. It could be that there should be a flat washer between the nut and the bottom of the case.

Super easy assembly, applications are vast. This item is a no brainer. Put these on everything you want see or control the temperature of. Another must have, and this one is the one to buy.

The single unit I received had one of the setting buttons missing (or was apparently never installed). This rendered it useless. However, because it was so inexpensive I didn't bother trying to return it and simply ordered two more units from a different vendor with higher average customer reviews. I'm assuming that most of these type units are mass produced to a very low price point. Unfortunately, poor quality control is the inevitable result. Apparently the W1209 can function well if you receive a good one, so since they are so inexpensive, I'm going to roll the dice again and will hopefully receive one that functions as intended.

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.

I just wish it could display Fahrenheit instead of Celsius. Also, wires kept coming loose from the screw terminals and I ended up removing the screw terminals and soldering the wires directly to the board and the acrylic box is extremely fragile and one of the holding tabs broke when I assembled it together.

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

Assembly took nimble fingers, but it went together. That's when the fun started.It came with no instructions, but I found some on the web. I wanted to control a heating pad to regulate the temperature in a box for sour dough starter. The range I wanted to keep it in was 70-75 degrees Fahrenheit, or 21.1 - 23.8 Celsius.In initially was getting only a range of and upper limit of 23.8c, lower limit of 21.1c, when I was trying to use it like I expected it to do. After a lot of playing around with it and a Pakistani video that explained fairly well, I got it working.
