Copeland Comfort Control (Alco) 065365 Control

The Copeland Comfort Control (Alco) 065365 (Model OMB-JB1) is a professional-grade compressor crankcase oil level protection control designed specifically for Copeland Scroll series ZF, ZB, ZR, and ZS, as well as semi-hermetic compressors from Carlyle and Bitzer. This 24Vac unit functions as a self-contained controller by integrating a reverse Hall-effect sensor with an internal solenoid to manage oil supply without the interference from magnetic debris or foaming common in optical sensors. With a high 870 PSI maximum working pressure and a 350 PSI MOPD, it ensures reliable crankcase oil management for HFC, HCFC, and CFC refrigeration systems. The included junction box and 1/4" male flare fitting simplify field installation. A built-in 5-10 second time delay for low-level signaling prevents nuisance trips, while the 120-second alarm delay and SPDT alarm switch provide robust protection by allowing for compressor shutdown before damage occurs from insufficient lubrication.

• Precision Oil Targeting: Uses a reverse Hall-effect sensor to provide accurate level measurement, unaffected by oil foaming or contaminants.
• System Compatibility: The only approved oil level control for Copeland Scroll compressors, ensuring optimized performance and fit.
• Integrated Protection: Features a 5-time lockout logic to safeguard the compressor from chronic low-oil conditions.
• Visual Diagnostics: Equipped with an integral sight glass and LED status lights (Green/Yellow/Red) for immediate field troubleshooting.
• Debris Management: Includes a sacrificial magnet to keep the sensor path clear of metallic particles.

Is an adapter required for installation?
For reciprocating compressors, the unit typically mounts directly to the sight glass port. For Copeland Scroll models, a specific flange adapter (such as the OMB-ACA or OMB-ACB) is required based on the compressor's thread size.

What do the LED codes indicate during operation?
Green indicates power is present. Yellow signals that the oil level is below the midpoint and the fill solenoid is energized. Red signifies a lockout or alarm condition after the 120-second delay has expired without level recovery.

Can the solenoid coil be replaced separately?
No, the OMB-JB1 is a self-contained unit. Removing the control box or coil will damage the Hall-effect calibration; the entire assembly should be replaced if the solenoid fails.
