I bought an analog temperature Controller from Northern Brewer a while back. After reading about the controller here, I am not comfortable using it for Fermentation temps. a 3 degree variance is to much for me. So, which Temperature Controller would you recommend for a Chest Typer Freezer?


And about Freezers. Will they hold a temp of 65 degrees? I mean, they are meant for keeping things frozen. What happens to them when they are not working for what they are meant to be used for? Reason I ask is that I will be buying SOMETHING to primary Ferment in and Lager in. It's a toss up between a Chest Freezer or a Refridgerator. Chest Freezer I like better because of more usable room without having to add racks for a second Carboy, like I would have to do with a refridgerator. But the Fereezer and the higher temps worry me. Any comments?

This is the unit I use and have had great success for 5 years. Very accurate and easy to set temperature.

No big deal using a freezer. The internal thermostat will always try running the compressor but the external controller breaks the circuit. When it need to cool, it will run. The cycle is just a little shorter for keeping warmer temps.

I have two Ranco 111000. I like being able to use them for heating or cooling and you can set the deadband down to 1 degree.

3* is just fine as the liquid will cool and warm much slower than the surrounding air. By having too narrow a deadband it's possible that the compressor will have a shorter lifespan because of the constant cycling.

exarcly! There are many other things to worry about than a 3º swing in ambient temps.

After having no temp control in Tx for the longest time, I'm giddy as a schoolgirl with the 3deg swing.

(2) Ranco ETC 111000's. Very satisfied.
Adjustable variance down to 1', heat or cool, digital display, easy to operate.
Available on Ebay for about $50 w/ s&h.
I'll probably buy a 211000, (heat and cool) if I decide to move my ferm chamber out to the garage next year.

I bought one of those Ranco's and have it set to a 3 degree variance. I currently have it set for 65F with a 3 degree variance so it kicks on when the temp reaches 68F, then I guess because of the cooling lines when the switch kicks off the freezer temp goes as low as 62F. It doesn't matter though, with this setting my beer stays at a permanent 66F which is just where I want it.

What does everyone do for heating during colder months? I need to get my carboys out of my living room and into my garage, but since i live in michigan, i have more months that I would need to heat up to the Mid-60's versus needing to cool down. Assuming i have a chest freezer and a controller, is it wired to some kind of heating system (light bulb, ceramic bulb, etc..) and kick on when it needs heat?
