What to look for in a temperature controller

Question

I've decided to begin assembling the components for temperature control, as I am walking around telling new homebrewers that its the best thing one can do to improve quality, yet I myself don't have it. I am going to buy a temp controller and a freezer (but will need to make space, as I live in a small rowhouse), but was wondering which controllers are best for homebrewing. There seems to be quite a bit of price difference out there. At the high end, I was looking at this one by Ranco:

Also by Ranco, but a third the price: http://www.amazon.com/RANCO-ETC-111000-Digital-Temperature-Control/dp/B0015NV5BE/ref=sr_1_1?ie=UTF8&qid=1328194583&sr=8-1

I've also heard of some people having good experiences with Johnson, such as this one: http://www.amazon.com/Johnson-Controls-Digital-Thermostat-Control/dp/B00368D6JA/ref=sr_1_2?ie=UTF8&qid=1328194583&sr=8-2

I would prefer to have to do minimal wiring/splicing, etc. myself, as my wife is already patient enough with my obsession and don't want to add and electrical fire and burned-alive dog to the mix to test it further.

Maybe this should be a community wiki?

Thanks in advance!

Answer 1

I use a Love TS-13010. The price has gone up a bit, but you may be able to find a deal on the eBay. I wired it into an electrical box so I can just plug any devices I want temperature controlled into it. Then you don't have to ruin the wiring in your freezer, and you can convince your wife that you can still use it to store meat :)

Here's how mine is wired:

And since the front is splash-proof, I even used one to replace the analog temp control in my kegerator fridge!

Answer 2

Two weeks ago I was in exactly the same place you were. I bought the Ranco model, just haven't bought my freezer yet (gotta clear space in the garage first). I'm also considering a thermowell.

My criteria were that the controller needed a full range of brewing temps (~32-80F, which some cheap home aquarium models don't), that I could change it from heating to cooling, and that it be pre-wired.

I chose the Ranco ETC-111000, pre-wired from ETCSupply.com. Haven't had a chance to use it yet, but it seems solid. I chose it over the Johnson model because you can change the state (cooling or heating) in the menu. With the Johnson model you have to unscrew the faceplate and change jumpers.

The Ranco ETC-211000 model is their dual-stage model- one outlet controls heating, one controls cooling. I don't anticipate that I would use that feature. At worst, if I need simultaneous heating and cooling I can get a second controller.

After making my purchase, I found this two-stage pre-wired model from Rebel Brewer, which I might have bought if I had seen it before. It's a little bit more expensive than the others but cheap for a two-stage model. The submersible probe is a plus but it only reads in degrees Celsius.

Answer 3

I use this analog thermostat from Johnson with my keezer. (No affiliation with Rebel. Just like them personally.)

Doesn't require any splicing/wiring. Very convenient. Just need to run the temperature probe into the freezer somehow. (I have a collar on mine, so it works perfectly.)

Answer 4

I picked up a unit on ebay that came with it's own thermocouple and SSR for about $40, free shipping. You'd need to build a housing like the Love digital one, but it's a fun little project and it works perfectly. I have the same units hooked up to my electric HLT for controlling sparge temp and one on order for my electric RIMS system I'm building. They're great!

Answer 5

I have 2 of the Johnson analog controls. Super easy to use, no wiring involved. Works like a charm. I just need to pick up a Thermowell sometime soon.
