Review: Worked on 12vdc fan - The instructions and diagrams have some English... I wired 12volt DC fan and was able to test it quickly. Seems to work like a normally open relay. Adjustment was simple, hit set, then top bottom increases and bottom button decreases the target temp. I set to 75 and used a candle to trigger a change. Fast response.
Review: Works as described - Wiring and instructions are a little complicated, but is installed and working perfectly. Very pleased. Longevity is yet to be determined 😉

### ⭐⭐⭐⭐ A decent temperature controller that can handle a 20 amp load at 12 volts
*by D***. on September 29, 2025*

If you need a basic and cheap temperature controller, this one isn't half bad. I'm using it on a Chinese mini excavator to control a 12 volt fan on the hydraulic cooler. It comes defaulted cooling mode, so you pretty much just hit set, select your target temperature, and it will turn on a few degrees above that set point using the default settings. I knocked it down a star since as other reviewers have mentioned, if you hit both buttons at once, it resets the device. I also wished it had a more robust terminal block, but for the price, it's not bad and it's working as intended. I also deducted since it comes with a very short NTC thermistor. I had to buy a three pack of 1 meter NTC sensors to be able to reach the hydraulic cooler where I wanted to measure the temperature. Those sensors are cheap and it's plug and play with a small 2-pin connector.
