🌡️ Solar Heater Temperature Differential Controller Review

It doesn't run directly off 110v so I removed the 220v to 12v transformer (soldered off the board) and used a 110v to 12 V-DC wall adapter used. Will still switch to 110VAC.

All diagrams and instructions are written in Chinese characters. Revain put me in touch with the company and instead of giving me helpful answers, I seemed to be talking to a bot that answered my answers with irrelevant questions.

Does exactly what it's supposed to do. Use it to control the pump of my solar system. I really wish there was 120VAC vs 240VAC, but I converted it to 12VDC operation anyway. It would be better if the labels were in English instead of Chinese, but if you look for it there are instructions online in English.
