Ranco O10-1473 Temperature Control

When you need a reliable primary control for medium-temperature applications, the Ranco O10-1473 Temperature Control is a versatile industry standard. Specifically engineered for commercial refrigeration, this SPST cold control features an adjustable range from 0°F to 55°F, making it compatible with self-contained refrigerators, walk-in coolers, and display cases. The 72-inch capillary with a remote bulb provides ample reach for precise sensing across diverse evaporator and cabinet configurations. Equipped with a NEMA 1 non-conductive enclosure and laser-welded bellows, this unit is built to withstand the rigors of high-cycle duty in demanding HVACR environments. The adjustable differential—ranging from 3°F to 20°F at the low end—allows technicians to fine-tune compressor cycling to prevent short-cycling and optimize energy efficiency. With universal mounting capabilities and a high-accuracy 7-revolution adjustment screw, it serves as a robust cross-reference for numerous OEM controllers from brands like Carrier, Hobart, and McCray.

• Precision Control: Features a wide 0°F to 55°F temperature range for medium-temp refrigeration.
• Engineered Durability: Laser-welded bellows and a heavy-duty plated steel frame ensure long-term mechanical reliability.
• Ease of Installation: Includes universal mounting brackets and a 72" capillary for flexible sensor placement.
• Safe Design: NEMA 1 enclosure with a non-conductive cover protects against accidental contact with electrical terminals.
• Technical Flexibility: Adjustable switching action (Opens on Drop) and a variable differential to meet specific equipment specs.

What is the switch action for the Ranco O10-1473?
This model is a Single Pole Single Throw (SPST) control that Opens on Temperature Drop (Close on Rise), typically used as a primary temperature controller to cycle the compressor or solenoid.

Can the differential be adjusted on this model?
Yes, the O10-1473 features a wide-range adjustable differential. At the low end of the temperature range, the differential is adjustable between 3°F and 20°F to help manage compressor run times.

Is this control compatible with high-voltage applications?
This control is rated for 120V/240V AC applications. Always verify the Full Load Amperage (FLA) and Locked Rotor Amperage (LRA) on the motor nameplate against the ratings inside the control cover before installation.
