Resideo PA404A1033 Pressuretrol Controller
For steam heating systems requiring precise high-limit protection, the Resideo PA404A1033 Pressuretrol Controller serves as the industry standard for steam boiler pressure control. Designed for installation above the water line, this SPST switching device breaks the electrical circuit to shut down the burner when steam pressure exceeds your designated safety threshold. It features a broad 0.5-9 psi adjustable pressure range and a 1-5 psi additive differential, allowing technicians to fine-tune boiler cut-out settings to prevent short-cycling and maintain system efficiency. The stainless steel diaphragm provides long-term reliability against corrosive vapors, while the 1/4" female NPT connection ensures a direct fit on standard pigtail syphons. Whether you are performing a Honeywell PA404A1033 replacement or a new installation, this low pressure steam controller handles line voltage, low voltage, and millivolt circuits with ease, ensuring robust HVAC high limit safety for commercial and residential boilers.
Key Benefits for the Contractor- Precision Tuning: Features a top-mounted adjustment screw for the main scale and an internal dial for adjustable differential pressure settings.
- Broad Compatibility: The SPST snap-acting switch is rated for 24V, 120V, 240V, and 277V, making it a versatile boiler pressure switch for various control circuits.
- Durable Construction: Equipped with a stainless steel diaphragm and a rugged gray enamel case to withstand mechanical room environments.
- Simplified Installation: Standard 1/4" female pipe threads allow for quick mounting on a steam pigtail syphon.
- What is the recommended minimum set point? For reliable operation, the minimum set point should be the differential setting plus 1.5 psi.
- Does this require a pigtail syphon? Yes, always install with a syphon to protect the Pressuretrol controller diaphragm from direct steam contact and scale buildup.
- How do I adjust the differential? The additive differential is adjusted via the wheel located inside the case; the circuit breaks at the set point plus the differential on pressure rise.
- Can I use this for millivolt systems? Yes, the PA404A1033 is suitable for self-powered millivoltage applications.
