The Ranco ETC-111000-000 is an excellent temperature controller. Easy to program with a clear display and very accurate. I've used it for my fermentation chamber and it maintains temperature perfectly. Highly reliable.

Installed the ETC-112000 for a 24V cooling application and it works flawlessly. The sensor is responsive and the control is stable. Great build quality and much better than cheaper alternatives I've tried.
