Product review (5 stars): Excellent temperature controller for fermentation
I recently purchased this dual stage temperature controller for controlling my beer fermentation temperature.  This unit does the trick and its very simple to program!

My electrical knowledge is very basic.  I have done many electrical projects around the house but I'd still consider myself quite a novice.  Wiring this unit was pretty straight forward.  The manufacturer's website is much easier to follow than the manual.  It took a run to lowes and about an hour and a half to wire it all up.  I wired it up to an outlet and programmed it for one socket controlling heat and the other controlling cooling.  I have the cooling set at 67 and the heat set point at 65.  It maintains a constant 67/68 during primary fermentation.

I did extend the sensor wire as it is only 2+ feet.  I used 10 ft of 22 awg and it seems to works just fine.

I replaced my Johnson single stage A419 unit to get a much more precise temperature and can't be happier. Highly recommend this unit!
