Questions about this item

What does the 175–215°F range mean once the control is installed in a furnace?

The snap-disc opens the fan circuit when the heat exchanger reaches the set point between 175°F and 215°F, then closes again as it cools, so the blower runs only while sufficient heat is present.

How does the snap-disc interface limit the control’s operation in practice?

The bi-metal disc reacts directly to temperature, giving a fixed differential that cannot be programmed, so the fan cycles on and off strictly within the 175–215°F window you select.
