Product review (5 stars): Great 2 stage temp controller for Fermentation fridge!
Purchased this unit to control a refrigerator used as a fermentation chamber for my Home brewed beer. For less than the most popular single stage units, I got this 2 stage digital unit. I've been using it for 9 months now and still functions perfectly.
When first used, the sensor was slightly off, but the unit has a calibration setting in the programming to correct that. The 2 stage function is nice because I can set one plug to cool, and one to warm, and with nothing more than a refrigerator for cooling and an incandescent light bulb or small heater for heat, I can control the fermentation temps.

Connecting the wiring to the unit and installing the outlet IS a task that you should be comfortable with, or have an electrician or technician do it for you. Im fortunate enough to be an Electronics tech and did it myself, and have since suggested this unit to friends and I wired theirs for them as well.
That being said, this is a quality device, at a price that is too good to not at least consider. IF and when my unit malfunctions, or I need another, this WILL be the one I purchase again.
