Compressor won't start

[RKElectricalman]

I know I should start a new post for this, but since It's the same topic, I'd rather get help from the experienced few on this topic.

We have sort of the opposite issue, my compressor starts by the use of compressor->Start(); but does not automatically turn on. I've used a multimeter to test if the switch's state changes after reaching 115psi, and it does... but the compressor never starts.

Originally, I declared the compressor on digital one and relay one:

Compressor *compressor;

then:

compressor = new Compressor(1,1);

and when that failed, I tried changing the digital switch to DIO 5 (5,1) in the code and sidecar, and still nothing!. The relay I know for sure works properly, I've tested it, but I don't know what else it could be! Also, I'm pretty sure the switch is wired correctly... black and white pwm wires on the switch. Any Idea what could the problem be?

When you run the code, does the spike relay flash green or red instead of staying at orange color?

no, the relay stays solid green and powers the compressor even after the pressure goes above 120psi...

I'm looking into implementing code that solely reads the value of the switch and controls the compressor without using compressor.Start(); is the switch supposed to read 1 or 0 after reaching 115 psi?

We've tried two different pressure switches, and I just tried using the relay and digital input seperately...

The compressor turns on, with the relay green but never off still!

I don't know what to do, and it's odd why it's not workign right now.. any thoughts? We've even changed the relay's out...
