I was led to believe that the second socket marked "cold" could also be used for heating. The instructions are very sparse and difficult to understand. I've watched countless YouTube videos trying to figure out how to set this up properly and haven't been able to get it to work like it should. I wouldn't recommend it unless you're a temperature wizard. Buy Inkbird, that's what I did.
