tb....what is it you are attempting to accomplish? While my Colemans use Balboa M7 controls and I'd hazard a guess that if you are looking at your dip switches......that you are in over your head. On the current M7 controls, you turn off switch 10 and then program certain functions for the tub. Remote control operation, speeds of pumps, all sorts of things can be done with the top side controls. However, this really should be done by a service tech. The dip switches are turn off with the system fully powered up and if you slip you will get shocked. Going back to your original question, a circ pump runs 24 hours and your tub could still have extra filter time. As I recall Sundance does something like that. TB is you are have these kinds of issues, call your manufacturer and describe your problems to them. They should call the dealer and get him headed in the right direction. TB be patient, don't get in so deep that you regret your actions. Your dealer sounds like he could get block headed and mess with your warranty. Call the manufacturer now and get the ball rolling from that end. Your circuit board is very live, 240 and 50 amps and if you are in a puddle......then poof......be careful
