Honeywell Pressure Controller 1 psi - 5 psi Adj. The PA404 is a series 40 (2-wire, SPST) pressuretrol controller for use in 24, 120, 240 or 277 volt control circuits or in self powered (millivoltage) applications. Features The PA404A is a pressure actuated high limit, safety control for steam heating boilers. It breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level.The PA404B is used with suspension-type unit heaters to make the fan circuit when a...
