what settings should be used on cut-in/cut-out switch on home steam boiler. or what should be the maximum pressure in psi allowed?
Boilers are designed to each manufacturer's specifications. There should be a specification plate on the boiler giving you this information. If not, I would go back to the manufacturer, with the model and serial number, and request that information from them. For someone to give you the pressure settings over these pages would be very dangerous.
