Copeland Comfort Control (Alco) 097998 Pressure Control

The Copeland Comfort Control (Alco) 097998 Pressure Control, specifically the Model PSC-B6S, is a heavy-duty mini high pressure control engineered for precision sensing in commercial HVACR applications. This manual reset switch acts as a critical safety cutout, preventing compressor damage by monitoring high-side pressures between 145 and 623 PSI. Designed as a direct replacement for PS3-B6S, it features an SPDT switch configuration, allowing for both system cutout and remote alarming. The unit is equipped with a 1/4" SAE flare fitting including a valve depressor for easy mounting on Schrader ports, and it utilizes a DIN plug with a 36-inch cable for secure electrical termination. This control is fully compatible with CFC, HCFC, and HFC refrigerants, including R-410A, thanks to its high 695 PSI maximum pressure rating and integrated pulsation snubber that protects the bellows from pressure spikes.

Key Benefits for Contractors

• Enhanced Field Reliability: Features a rugged bellows design with a built-in snubber to withstand vibration and hydraulic shocks common in refrigeration lines.
• Versatile Electrical Compatibility: The SPDT (Single Pole Double Throw) contact allows for flexible wiring to meet various control circuit requirements.
• Simplified Installation: The direct-mount 1/4" flare fitting and 36" cable lead reduce labor time when replacing standard PSC or PS3 series controls.
• Safety Compliance: Manual reset functionality ensures technical intervention is required after a high-pressure event, protecting the compressor from cycling on a fault.

Common Questions

Is the PSC-B6S compatible with R-410A systems?
Yes, with a maximum working pressure of 695 PSI and a cutout range up to 623 PSI, this control is suitable for high-pressure R-410A refrigeration and AC applications.

Can I use this for condenser fan cycling?
While typically used as a high-pressure safety cutout, the SPDT switch logic can be utilized for condenser fan cycling if your application requires a manual reset at specific pressure thresholds.

What is the factory default pressure setting?
While adjustable within the 145–623 PSI range, these units are commonly factory-preset to 395 PSI for standard commercial high-pressure protection.
