I'm using it as a outside temp sensor to break the W3 call from the stat when the OA temp is higher than 38 degrees.
job was spec'd to only allow aux heat strips when the temp is lower than 38 deg and the ranco was only 6 bucks more than a honeywell mechanical temp control so i decided to use it.

OK gotcha.

Sorta gives me a headache though cause it reminds me of a job Im behind on for controlling some valves. Using same din rail mounted relay blocks and relays.

I have built units like that in the past, try getting a label maker, as it makes for a better job.
I also use alum diamond plate for the backing, makes it shin.

Nice work, a++
