Question about Heating & Cooling
This may be caused by accumulation of sludge in the steam trap (the looped tube that connects the pressuretrol unit to the boiler). the sludge restricts the pressure from reaching the diaphragm in the pressuretrol unit. So it gets a false reading. Clean or replace the tube and see if normal function resumes.

Here's a link that may help it explains the controller and how it works. http://customer.honeywell.com/techlit/pdf/PackedLit/60-2341.pdf I personnally would not be adjusting this control as you have been because its a safety that shut off the unit in a unsafe condition. If it's malfunctioning then thaat is when you need to call a service company to check out why. You would not want your unitto explode because of a high pressure condition. Please have your unit serviced.
