Starting and Stopping Compressor

[Iron Drakes]

Any insight on this issue would help. Are there rules how the compressor must be powered on and off?(through a specific relay,jaguar, etc.) Can I power on with a Jaguar, is that possible, legal? I know I can write the code for that but right now I have power going to a spike relay connected in relay 1 on digital sidecar and can't get code to turn spike on and off..

Any help will do.

Thanks

P.S. I have Compressor(1,2) program running, but I am not sure exactly what it is doing.
