Johnson Controls Dial Thermostat
- Dialing in Temperature Control
Hey folks, I use a Sanyo 4912 as a fermentation chamber. Just started with it. I noticed the other day that even though the fridge is set to 70* the sticky thermometer on the carboy says 74*. Do

Hi Folks, I recently bought a 7cu. ft. Holiday chest freezer and a Johnson Controls A19AAT-2C Freezer Temperature Controller to manage the temperature. I just ran the probe under the freezer lid t

Pros: Works as advertised
Recommended? YesI use it to regulate the temperature inside a chest freezer. I stuck a rubber hook on the outside of the freezer to hold the thermostat and hung the probe inside, just closing the lid over the wire. It probably affects the seal a little bit, but not enough to notice. I'm not too worried about the temperature swing, as that little change in ambient temp is not going to cause the temperature of the beer to change nearly as much.
I get much better results than when I tried to use evaporative cooling to keep my lagers at the correct temperature.

Pros: It works.
Cons: 4 degree swing is a little much. Loses calibration easily.
Recommended? YesSee above.
Pros: good price
I have the Vissani kegerator (feeks like a piece of crap, but it should work for fermenting ales) ,and just bought the johnson temp control. My question is, where do you insert the temperature probe into the fridge? I was going to go through the CO2 hole in the back, but it doesn't seem like a good seal at all, and I'm also worried the keg will hit it.
Thanks in advance for any suggestions,
Pros: Easy to use, no wiring. Tight, stable temperature control. Inexpensive, and did I mention friking easy to use? :p
Cons: Not exactly posh asthetically. Mounting hardware is a bit wanting. Some have indicated that the probe wire is delicate but i dont find this an issue as I treat my equipment with care.
Recommended? YesVery good product with reliable functionality that is a breeze to use. It is not the sexiest thing on the shelf but it does the trick.
Pros: Simple setup and tight range on temp control.
Cons: Probe capillary tube is very delicate, so be careful where you install it.
Recommended? YesGot it as one of the MoreBeer "Deal of the day" sales for a smokin price. When I converted a 3.9cf MagicChef to a kegerator the Johnson worked like a champ and keeps inside temp within a very tight 2-3F range. Added a muffin fan from dead computer and it piggy backs on the controller with the fridge so there is good air movement inside the fridge.
