I am wondering if there is any real difference between the Ranco controller and the one from Johnson Controls.

I will be controlling a Sanyo 4912 for fermenting and a 7 cu ft freezer for kegs.
 
That johnson, does it control a heating device and a cooling device at the same time so you can set a controlled temperature range?
 
I better stick with the Ranco then. My garage can be cold in the night and hot in the day, extending above or below a fermentation temperature I'm trying to reach.
 
I wanted to thank all of you for your advice...

got the Ranco off EBay, and the wiring was not that big a deal ..

Connected the 15 cu ft freezer, and set it to 42 ... I was amazed how fast the freezer came down ... holding steady with 3 degree differential (is that enough ?)

I am lagering a clone brew called Road Dog Ale, which calls for 42 deg for 3 weeks in secondary. It is nice to know that the temp will be steady.

Looks like lagering is now part of my vocbulary ...
