Best in Class
By H.A.H. (from Garfield Heights, Ohio) on 9/27/2015
Purchased 24 units to convert a church school building to electric heat as boiler and pipes needed overhaul to the tune of $50,000 plus. Wiring and hook-up was a breeze. I highly recommend these programmable thermostats.

Installed and working great
By The Shootist (from Marion, Ohio) on 1/20/2012
I purchased 5 of these thermostats for a 2 bedroom house because the bi-metal thermostats that were only a year old did not regulate the heat very well. We watched the themometer and there was a 10 degree differance from the time they kicked on till when they shut off we were either hot or cold. The install was as easy as it gets and they are working perfectly.There is not a temp shift at all the house and bedrooms all stay a constant temp.The quality better than expected.Looking forward to see what kind of savings they will have on the electic bill.
