Awesome thermostat

This thermostat was a little overkill for this particular use I had.
Super well made and easy install. I have others in use as well and love them all. Easy to control temperature adjustments.

Legacy Review
works as advertized

I bought this two years ago for my greenhouse build, the first stage opens the shutters and turns on an additional circulation fan, the second stage turns on the big exhaust fan as temps continue to rise. in early spring / late fall simply opening the shutters controls the temp without the big fan ever needing to run saving power. it was a good investment and hasn't gave any issues at all.
