Hi Jerry-
Don't know if you've already seen these in my past posts, but will include adjustment info I have. Yours may be quite different than mine in control configuration, especially if your controller isn't on the electric bay ceiling, but perhaps they'll be of some help; the sensors for mine I believe are inside that box.
Forgive the lack of clarity in some images - that's what HWH faxed a repairing dealership in 2006, so my copies weren't the best to start with, much less after scanning and reducing resolution so they'd fit within this site's parameters. A call to HWH tomorrow might be a good idea if nothing else works; who knows what your repair techs did to your system.
