It has to have a 12 VDC power supply to operate the controls. That is probably the problem. Let me know if you need more when you go to install it. Be sure you keep the polarity correct on the 12 vDC feed. Hope that helps here. Please get back to me later as all follow ups are included in our fee.
Just checking back in to see if that information was helpful here or do you still need some additional input from me on this issue?
