oh woops sorry about that, I tried both (1,1 and 4,2 because it came from an example), but neither worked. So the pressure switch isn't required to get the compressor running? like I can just set it, but leave the pwm out and it'll work as long as the compressor is hooked up? Or did you mean go ahead and try to get the relay working eg using the Relay class.
I know you can run the compressor using the relay class, but I also know that using the compressor class simplifies things a lot, so I want to avoid that.
