White-rodgers 16 09 101S1 Refrigeration Temperature Control

Product Description

The WHITE-RODGERS 16 09 101S1 is a refrigeration temperature control designed to regulate temperature in commercial and light commercial refrigeration applications. The control uses a close-on-rise switch action, meaning the switch closes as the sensed temperature rises, making it suitable for cooling system staging and compressor control. It features an adjustable differential of 3.5 to 40 degrees F, giving technicians flexibility to fine-tune the operating range for a given application. A 5-foot capillary tube connects the sensing bulb to the control body, allowing installation in tight or remote sensing locations. Licensed refrigeration technicians and HVAC-R service professionals are the primary installers of this control.

This temperature control is intended for refrigeration systems where remote bulb sensing is required and close-on-rise switching logic matches the system design. Typical applications include walk-in coolers, reach-in refrigeration cases, and similar commercial refrigeration equipment. The adjustable differential allows the control to be set to match the specific temperature swing requirements of the refrigerated space or evaporator being controlled. Installation is typically performed during commissioning of new equipment or as a direct replacement during a service call on an existing refrigeration system.

Key Features

• Close-on-rise switch action for cooling system and compressor control logic
• Adjustable differential range of 3.5 to 40 degrees F for flexible setpoint tuning
• 5-foot capillary tube allows remote bulb placement at the sensing location
• Compact control body suitable for panel or enclosure mounting in refrigeration equipment

Compatibility

Designed as an OEM-style replacement temperature control for commercial and light commercial refrigeration systems requiring a close-on-rise, remote bulb capillary control with adjustable differential.

Installation Notes

Installation should be performed by a licensed HVAC-R technician or refrigeration mechanic. De-energize the equipment and follow proper lockout/tagout procedures before removing or installing the control. Route and secure the capillary tube carefully to avoid kinking, which can impair sensing accuracy. Local codes and equipment manufacturer guidelines should be consulted for proper mounting location and setpoint configuration.
