OK, so I've spent the last hour searching and reading old threads on Ranco setups. I purchased the prewired Dual Stage Ranco from Morebeer (http://morebeer.com/view_product/16664//Ranco_Digital_Two-Stage_Temperature_Controller_-_Wired, a Fermwrap heater, and a Craigslist standard top-freezer refrigerator. What would be the optimal way of setting this up? Say I'm fermenting a Rogue Shakespeare Stout (which I am), that I want to ferment at 60deg. Should I set the fridge at 58 with a 2deg differential, and the fermwrap at 62 with a 2deg differential? Also, I am using a thermowell with the probe from the Ranco inside.
Also, will the freezer stay frozen using this type of setup? I know that the fridge uses a fan to pull cold air from the freezer to cool it, but if it only turns on when the beer gets warm, will the freezer stay frozen?
Thanks as always for any help!
