Patterson-Kelley 10-0370-0713 Relay

The Patterson-Kelley 10-0370-0713 Time Delay Relay is a critical control component designed for high-efficiency boiler systems and water heaters. Engineered for 120V AC applications, this relay provides precise timing intervals to manage sequence of operations, preventing short-cycling and ensuring proper post-purge or pre-purge cycles in the combustion chamber. As a direct OEM replacement part, it maintains the integrity of the original control circuit, offering the exact coil voltage and contact ratings required for stable performance under high-demand commercial conditions. This industrial-grade relay features rugged construction to withstand the thermal stress and electrical noise common in mechanical rooms. Proper integration of this Patterson-Kelley control relay ensures reliable load switching for blowers, pumps, or ignition sequences, facilitating optimal thermal transfer and system longevity. For contractors performing HVAC boiler maintenance, utilizing this specific time delay control is essential for maintaining the safety parameters and operational efficiency of the P-K heat engine.

Key Benefits for Field Installation:

• Direct OEM Compatibility: Specifically calibrated for Patterson-Kelley equipment to ensure seamless control board integration.
• Precise Timing Accuracy: Prevents nuisance trips and equipment wear by maintaining strict timing sequences during startup and shutdown.
• Robust 120V Coil Design: Built to handle voltage fluctuations common in commercial HVAC electrical circuits.
• Simplified Field Replacement: Standardized terminal layout allows for quick boiler component swaps, minimizing system downtime.

Common Technical Questions:

Is this relay compatible with non-Patterson-Kelley systems?
While the 120V relay operates on standard electrical principles, it is specifically indexed for P-K equipment. Verify your wiring schematic and timing requirements before attempting installation in third-party systems.

What are the symptoms of a failing time delay relay?
Common indicators include the boiler failing to initiate the purge cycle, intermittent ignition delays, or the system staying in a pre-purge loop without advancing to the firing stage.

Can this relay be used for both pre-purge and post-purge functions?
The function is determined by its position and wiring within the boiler control logic. Consult the technical manual for your specific Patterson-Kelley model to confirm its dedicated sequence role.
