HVAC Limit Controller 120/240V AC
The Value Brand temperature limit controller is an SPST automatic-reset switch for surface-mount installation. It opens on temperature rise and closes again when conditions fall back within range. Designed for HVAC equipment that needs a simple high-limit safety cut-out.
Replaces Fixed-Threshold Limit Switches
Adjustable opening temperatures of 250°F and 290°F with closing points at 210°F and 250°F let you match the controller to the equipment instead of hunting a fixed-value part. The jump is worth it when the original switch is discontinued or when the application demands a different cut-out band.
Check Voltage And Mounting Before Ordering
Verify the supply is 120V AC or 240V AC and that the 2 in by 1 3/4 in mounting base fits the enclosure. Confirm the SPST open-on-rise action matches the control circuit wiring. No maximum or minimum control temperature is specified.

Questions about this item
What surface-mount base dimensions must the panel accommodate for this controller?
The controller mounts on a 2 in by 1 3/4 in base, so the panel cut-out or bracket must provide at least that footprint.
Which wiring step is most often missed when connecting the 120/240 V AC supply to the SPST contacts?
Installers frequently forget to verify that the load circuit is on the switched leg so the controller actually opens the circuit on temperature rise.
At what temperatures will the automatic reset close the contacts again after an over-temperature trip?
After opening between 250 °F and 290 °F, the switch automatically recloses once the temperature falls back to the 210 °F to 250 °F range.
