Ranco ETC-111000-000W Prewired Tstat

I've been using these with really good success especially where you don't need a proportional controller. They can be set for a very narrow temperature range, so even though they are not proportional, they can keep a pretty right range. They can handle a pretty heavy load so I am using them to control space heaters and fridges. Another advantage is they can heat or cool. I order them prewired from etc supply. I have also used them to control RHPs and they worked fine for that, too.
