Resideo PA404A1025/U Pressuretrol Controller with Subtractive 1 to 5 psi Differential Pressure

Product Description

The Resideo PA404A1025/U is a Pressuretrol controller designed for safety in steam heating boiler applications. It features a series 40 two-wire, SPST design for use in 24, 120, 240, or 277 volts control circuits. This controller breaks the electrical circuit to shut down the burner when steam pressure exceeds safe levels.

Built-in mechanism to prevent unsafe pressure levels.
Adjustable set point without needing to remove the cover.
Compatible with self-powered (millivoltage) applications.
Product Highlights

The PA404A1025/U controller works by utilizing a sensitive pressure actuated diaphragm that adjusts based on pressure changes. A lever mechanism operates a snap switch to control the burner behavior. The adjustment dial inside the case allows easy differential manipulation for accurate settings.
