You can try 8192 but be careful which other settings you change. Let me know if this works or not. If it doesnt then please start another post with a photo of the controller so i can find you the code

Which controller do you have? Pro? Delcos? Delcos 2 or 3000?

Each controller has different codes . Please reply with which controller it is.

Hello Friends,

Anyone has the service code for HV22 Hydrovane Compressor with Pro Controller. I need it to change the Star-Delta time. It is configured in 1 sec, so the compressor doesn’t run.

Service code reset. 8192-P20-enter-SD-enter-increase days.-C to return to main display-press= should cancel service alarm.

I have an HV37 Hydrovane compressor. It odes not start if you press the start button. It only indicates that the motor is running on the screen, but nothing is happening. I suspect there weas wire tampering to the controller as some were pulled out. Can you assist with a wiring diagram, especially the wires entering the controller?

Regards, Rod

Is the motor in fact running, or is not running part of nothing happening?
There are some wiring diagrams, but ones I’ve seen don’t include pin-outs.
Maybe put up a pic (or more) of the wires in question? There’s a bunch of wires, ya know…
