Ranco O10-1408 Temperature Control

The Ranco O10-1408 Temperature Control is a heavy-duty single pole, single throw (SPST) cold control designed for low-temperature applications in commercial refrigeration. This wide range temperature control operates within a setpoint range of -15°F to 40°F, featuring an adjustable differential of 3°F to 20°F to prevent short-cycling and ensure precise compressor cycles. Equipped with a 72-inch capillary tube, the O10-1408 allows for flexible remote sensing in reach-in coolers and walk-in freezers. The unit utilizes a copper sensing bulb for rapid thermal response and is housed in a rugged NEMA 1 enclosure. As a universal replacement HVAC control, it handles high-amperage loads, making it compatible with various commercial refrigeration relay setups. Contractors prefer this model for its reliable mechanical snap-action switch and ease of field calibration when maintaining critical storage temperatures in harsh environments.

• Wide Operating Range: Operates from -15°F to 40°F, making it suitable for both freezer and cooler applications.
• Adjustable Differential: Provides a 3°F to 20°F range to fine-tune system performance and protect the compressor.
• Extended Capillary: The 72-inch capillary allows for versatile placement of the controller relative to the evaporator coil.
• High Electrical Rating: Designed for 120V/240V AC applications, accommodating most commercial refrigeration motors.

Common Questions

Can the Ranco O10-1408 be used for both cooling and heating?
No, this is an O series Ranco control designed to open on temperature rise/close on temperature fall, specifically for refrigeration cooling cycles.

How do I adjust the temperature differential on this unit?
The differential is adjusted via the internal screw mechanism; rotating it modifies the cut-in and cut-out points to prevent frequent equipment cycling.

Is the capillary tube on the O10-1408 field-cuttable?
No, the 72-inch capillary is a sealed system containing a sensing charge. Cutting the tube will render the control inoperable.
