The differential is fixed at 40 degrees and will open the switch when it cools back down to 40 degrees below the set point. These switches are commonly located in the airstream and bring the blower on when the furnace warms up. The face diameter of the sensing element is 7/8". The two holes in the mounting flange are 1-5/8" on center. This part is covered by the exclusive Protactor two year limited replacement policy.

Purchased on Nov 18-2019 and failed at end of Jan 2020. I had it adjusted to only 100 degrees in a Beacon Morris garage heater to switch the 24 vac to turn on fan relay. Didn't last 60-70 days. Very poor performance.

Product did not work and was used. Terminals and mounting screw holes had scratches on them from being installed elsewhere. Appears to be the one someone replaced and sent back to seller.
