I bought this little temp controller thinking it was for 24vdc. The description offers a 12v or 24v option. The 24v is referring to the control circuitry only. The relay is still for 12v, NOT 24v, as you will find out once you have fried it. The description does point this out, but it can be very easy to overlook. If something is called 24v, then the entire circuit should be able to handle 24v. I doubt there are many applications where 2 different voltages are used without unnecessarily complicating things.Unless you are real familiar with terms like "hysteresis" the instructions (per the photos above) are not real easy to figure out. Terms like "Set point temperature" and "differential degrees" would have made it a whole lot easier to set.Once you figure out how to set your temperature and the switch-on point, and stay within the parameters of the relay, it's a neat little circuit at a great price. Hopefully the manufacturer can replace the relay with 24v capability.

I really hate Fahrenheit. I wish I can switch it.

It's 50 degrees off and (despite what the crazy instructions/description says) you can only adjust by +-10 degrees. I also couldn't get it to turn the relay off.

I got the 12V in red. Accuracy compared to multi-meter is good. Issue was with buttons, they work very well but are relatively fragile compared to normal 6x6 micro momentary 4 pin buttons because this module uses the tall post versions. The 6x6 design wasn't meant lateral torque but the posts makes it easy to accidentally tap them over. Popped one right out during assembly into DIY fan build. Easily replaced as the part is very common and I happen to have a bin full of them. If you don't be careful. Otherwise, worked out great for me.FYIP0 = Cooling or Heating Mode, "C" or "H", default "C".P1 = Hysteresis Setting, 32F - 68F, default 2.P2 = Temperature Correction, 14F to 50F, default 0.P3 = Set Run Time, 0 - 240 minutes, default Off.P4 = Set Stop Time, 0 - 240 minutes, default Off.P3 setting "1" means that the thermostat is running for 1 minute to stop and long press SET to trigger again.P4 setting "1" indicates that the thermostat starts working after 1 minute. Set the digital tube will not light until 1 minute after the normal work. Press SET repeatedly to trigger again.
