The dual stage isn't for maintaining multiple temperatures. There's only one temperature probe. It's dual-stage in that it will turn one outlet on when the temp goes too low, or the other outlet will turn on if the temp goes too high.

Ok, thanks for the clarification. Lol

It looks like we are all learning something here.

prewired temperature controller = $84

$414 to fully temperature control a 10 gallon batch.

vs $1900 for the morebeer temp controlled 14 gallon conical.

the temperature controller is a TEC cooler that's only capable of a limited 20 or so degree differential... so you can't crash cool, and forget about lagering.

as far as the benefits of using a conical fermenter in and of itself, for a homebrewer, I don't see them. Autolysis isn't the same kind of issue for small homebrew batches as it is for large pro batches with high pressures on the yeast cone. Also the benefits and cost savings from yeast harvesting may be significant but probably only if you're brewing with the same strain multiple times per week.

So i took your advise with the chest freezer. I found a 9 cubic ft freezer at lowes for $276. Is there a link on how to hook up a digital controller to it? I have not done anything like this before so i want to make sure i'm going to do it right the first time.

Hey there I live in Ventura too. I think you still need some sort of temperature control. You don't want your fermentations to be ping ponging around. I see you are looking to brew 10 gal. batches which is what I brew. Here is what I do for fermentations...I ferment in 15.5 gal sanke kegs. The kegs are put in large rolling buckets and filled with water. I then use an aquarium heater to keep the temperature of the surrounding water at the temp I want. Since I am using stainless kegs their is direct temperature transmission between the water and the beer. Essentially I know that the water and beer are the same temp. When you need to rack out of the fermentors into kegs you can either push with CO2 or an auto siphon works. My whole set up costs about 125 bucks....it was cheap enough that I have two. When it does get warm you can always throw in some frozen water bottles. This summer I am going to build a cooling kit though. PM me if you want to see it...

get an extension cord with ground prong and just google etc 111000 wiring guide. there will be some guides that eliminate the ground prong, ignore those. it's pretty straightforward. you just need a wire stripper and a screwdriver.

that's for the ranco anyway. the johnson controls version works just as well from what i have read. the important part is to tape the temperature probe directly to the glass of your fermentor and not let it dangle in the air.
