Review on Digital Temperature Controller 100 240V Thermocouple by Bernard Her

English "Instructions" is incomprehensible (apparently automatic translation) and incomplete (links to sections that do not exist). The second sheet in Chinese has very clear differences in tables from the English manual. The picture shows the branding "Berme" but mine was labeled "BERM"; Instructions for the first one are easy to find online but not the BERN I got and they are different. It's either defective or set up incorrectly for my application and never turns off the heater regardless of the temp reading. I've already spent several hours trying unsuccessfully to get it to work and will likely return.
