Ranco A22-1114 Control

Engineered for high-reliability commercial refrigeration and air conditioning applications, the Ranco A22-1114 Control is a versatile SPST temperature control designed to govern compressor cycles with precision. This industrial-grade cold control features a temperature range of 60°F to 91°F with a tight 5°F differential, making it ideal for maintaining critical climates in reach-in coolers, vending machines, and room air conditioners. Equipped with a 54-inch capillary tube, this cross ambient thermostat allows for flexible bulb placement even in complex cabinet layouts. The inclusion of break-off shafts ensures compatibility with various dial depths, simplifying field replacements for technicians. Built to handle heavy-duty electrical loads, it supports 120V/240V/277V systems, delivering consistent switching performance in demanding environments. Whether you are performing a routine service or a complex system retrofit, this Ranco A/C thermostat provides the rugged durability needed to prevent short-cycling and maintain optimal evaporator temperatures under varying load conditions.

Key Benefits

• Broad Reach: The 54" capillary provides ample length for remote sensing in large refrigeration or HVAC housings.
• Mechanical Precision: Features an integrated "Off" position for manual system shutdown during maintenance or defrost cycles.
• Compressor Protection: Maintains a 5°F differential to ensure efficient cooling cycles and reduce component wear.

Common Questions

Is the Ranco A22-1114 suitable for low-temperature freezers?
No, this specific model is designed for a temperature range of 60°F to 91°F. It is primarily utilized in air conditioning, beverage cooling, and high-temp refrigeration units. For freezer applications, a control with a lower set-point range is required.

Can I use this control to replace a 3-wire SPDT thermostat?
The Ranco A22-1114 is a Single Pole Single Throw (SPST) switch that opens on a temperature drop. It is not a direct electrical replacement for SPDT applications requiring both normally open and normally closed contacts.

How do I handle the long capillary tube during installation?
Always maintain a minimum bend radius to prevent kinking the 54-inch capillary. Avoid contact with sharp edges or vibration points that could cause a loss of the volatile charge within the sensing element.
