Misread your original post...I thought you weren't getting it charged up to 120...

So your code from last year works with your current compressor/switch setup, but your new code doesn't? And it is using the same dig in/relay?

Just throwing some blind suggestions out....

Have you tried using printfs to see the value of the switch? Does it change when the pressure reaches 115?

What happens if you hard code the value of relay8_fwd to 1? Does the compressor turn on?

How far away from the default code are you? If you want, you can send me your C file and I can take a look for anything out of the ordinary.
