cut in cut out pressure switches
I am trying to select new pressure switches fron the Danfoss range unfortunatly the part nos I have are obsolete. the existing has a range of .52-1.72 L/S and 27.6-20.7 H/S the L/S I can get an alternative for, but' I am having trouble with the other in as much as the figures don't make sense to me as the alternative has a higher cut out pressure than the cut in, at 39.7 whereas the original has a lower cut out,the high side goes directly to the fan controller and the L/S I am assuming controls the comp relay if I use the new one then the fan once in won't cycle should I try and get one the compares with th existing cut out pressure ??

Can you not use an adjustable range switch?

Re: cut in cut out pressure switches
I think the op is referring to a fixed preset type switch, the type with a 1/4 TAIL with 2 spade connectors
Try wilspec they can manufacture any switch with any range
