This is a temperature sensor control system that I have previously built. I basically wanted to recreate a household central heating/cooling system.
The way this circuit operates is that the user can switch between three modes of operation via that one button, namely the: Ambient, Set and Run modes.
Ambient = Ambient Temperature
Set = Set desired room/object temperature
Run = perform cooling or heating in order to obtain and maintain that specific set temperature.
