I had bad luck, because I short-circuit the wires, and it burned. But it worked properly, before :). And yes you can change temperature values to any you want. I hope my one will be finished in near time. Don't hesitate to as anything you want - there is no fool question you could ask ;) The code and circuit is functional.

Sorry for the fool questions, Im a physician and electronic is my hobby. Reading the source code the temperature reference is in this interval between 17 and 20 Celsius. May I change to higher levels in the source code? What do you need to finish this project? It is functional if I try to build it now? Okay!I understand now.

The temperature when relay is turned on and off. Then is is done in code. The temperature is read and compared to reference. If is equal, then relay is turned on/off. There is hysteresis made in source code as well. What do you mean reference temperature? The temperature when relay is turned on and off. Then is is done in code.
