Fan switch for HVAC systems

The Value Brand control is a surface-mount temperature limit controller that opens a fan circuit at 90 degrees F and closes again at 110 degrees F. It operates on 120 to 277 volts AC with an automatic reset and SPST contact form.

Suits installers needing a simple open-on-rise fan

This unit fits applications where a fixed 20-degree differential and automatic reset are acceptable. It does not serve systems that require adjustable temperature settings, manual reset capability, or a different voltage range.

Fixed 20-degree differential

The switch opens at 90 degrees F and closes at 110 degrees F with no user adjustment. If the installation demands a different spread or a specific closing temperature, another controller must be selected.

Questions about this item

Will the 120-277 V AC input work with my existing furnace wiring?

The controller accepts 120 V AC and 277 V AC supply voltages for surface-mount installation.

How can I verify the fan switch is operating correctly after wiring it?

The fan should start when temperature reaches 110 °F and stop when it falls to 90 °F, giving a 20 °F differential.

What comes in the box and do I need separate mounting hardware?

The surface-mount base measures 2 in by 1 5/8 in; fasteners for the mounting surface are not included.
