Temperature Limit Controller
The ZORO SELECT fan switch is a surface-mount temperature limit controller designed for HVAC fan control. Its SPST contact closes on temperature rise and resets automatically when conditions return to normal.
Closes at 130°F / Opens at 115°F
This switch replaces basic on-off controls that lack automatic reset or a defined differential. The 15-degree differential prevents short-cycling, making the upgrade worthwhile when equipment protection depends on precise temperature bands.
120-277V AC Input Range
The controller handles standard low-voltage and line-voltage circuits up to 277V AC, covering most residential and light-commercial fan applications. It is not suited for loads that exceed the SPST contact rating or for systems requiring multi-stage or modulating control.

Questions about this item
What are the mounting base dimensions for this surface-mount fan switch?
The mounting base measures 2 inches in length and 1 5/8 inches in width for surface installation.
How do you wire this SPST switch that closes on temperature rise, and what is the common mistake?
Connect the line voltage to the two terminals; the switch closes automatically at 130 °F and opens at 115 °F. The common error is wiring it as a three-terminal device instead of the two-terminal SPST configuration.
When will this automatic-reset controller need replacement based on its temperature differential?
The 15 °F differential between the 130 °F close and 115 °F open points means the switch cycles automatically; replace the unit if it fails to close at 130 °F or open at 115 °F during testing.
