Ranco O10-1416 temperature control

The Ranco O10-1416 is a mechanical temperature control for refrigeration and freezer units. It uses a 72-inch capillary with a cross-ambient bulb to sense temperature. The single-pole single-throw switch closes on temperature rise. It is built for commercial and residential cooling equipment that requires automatic reset operation.

Installers needing 0 to 55 degree Fahrenheit range

This control suits technicians servicing walk-in coolers, reach-in freezers or beverage dispensers that operate within the 0 to 55 degrees Fahrenheit range. It is not suited for applications requiring a wider temperature span, digital programmability or a different contact configuration such as SPDT.

SPST switch action closes on rise

The defining specification is the SPST contact form that closes on temperature rise. This action determines whether the compressor or alarm circuit energises when the temperature exceeds the set point. Verify the required switch action before ordering.

Questions about this item

How much clearance do I need for the 72 in capillary tube and cross-ambient bulb?

Allow the full 72 in capillary length plus space for the cross-ambient bulb; the control body measures 3 1/2 in long by 2 3/4 in high.

Which terminals do the line and load wires connect to on the SPST switch?

Wire line and load to the two SPST terminals; the switch closes on temperature rise and resets automatically.

How often should the capillary bulb be checked for loss of charge?

Inspect the capillary and bulb annually for kinks, corrosion or loss of charge that would prevent the control from closing at 55 F.
