I have used the 24VAC version in many HVAC applications in the past. This time I used a breaker with very low ratings (max. .) and needed to add a 110VAC relay to control a kitchen exhaust fan in the attic. Works like clockwork! I had to mount it in a dual surface mount junction box with a custom overlay with an output and a pilot light. (there are photos).
