Value Brand 6UDY5 Adjustable Limit Auto Reset 135-215F hvac control

SKU CH-8H4W-Y0DPY

Adjustable surface-mount limit controller with automatic reset, SPST contacts opening at 135–215 °F and rated for 120/240 V AC

  • Adjustable 135-215 °F range suits varied HVAC needs
  • Auto reset restores operation without manual intervention
  • SPST open-on-rise protects equipment on over-temperature
  • Dual 120/240 V AC input fits common supply voltages
  • Compact 2 in × 1 3/4 in base allows surface mounting

Adjustable Temperature Limit Controller

The Value Brand 6UDY5 is a surface-mount temperature limit controller designed for HVAC systems requiring automatic reset protection. It operates on 120V AC or 240V AC input voltage with a single-pole single-throw contact that opens on temperature rise.

Surface Mount Installation Details

The unit mounts on a 2 in by 1 3/4 in base using surface-mount hardware. Common issues include wiring the SPST contacts incorrectly for the open-on-rise action or selecting a voltage mismatch between the 120V AC and 240V AC supply.

Pre-Order Compatibility Checks

Verify that your system requires an adjustable limit range between 135 Degrees F and 215 Degrees F with automatic reset behaviour. Confirm the control circuit voltage matches either 120V AC or 240V AC and that the mounting surface accommodates the stated base dimensions.

Questions about this item

How can I verify the controller is cycling correctly after installation?

Measure the switch terminals with a multimeter; the SPST contact should open when the sensed temperature reaches 175°F or 215°F and close again once it falls back to 135°F or 175°F.

What hardware is included with the 6UDY5 and what must I source separately?

The controller body and its 2 in by 1 3/4 in surface-mount base are supplied; you must provide 120 V AC or 240 V AC wiring, wire connectors and mounting screws.

Which temperature range should I select for a high-limit safety on a 240 V AC furnace?

Choose the 175 °F opening / 135 °F closing set if the safety limit is near 175 °F, or the 215 °F opening / 175 °F closing set for a higher limit; both operate on 240 V AC.
