Kitchen and Housewares Reviews of Johnson Controls A19AAT-2C Freezer Temperature Controller
Customer Review: Definitely Does The Job
Summary: 4 Stars
I purchased this controller to work with a chest freezer for a fermentation chamber. I will start by saying that this unit does control the temp of my wort within a pretty tight (3 degree F) range.
My only problem is that the temperature on the dial does not seem to be very accurate. I have placed my probe into the mason jar of vodka that I have for the terminal end of my blowoff tube, and to test it, I also placed a separate thermometer that I know to be accurate. The temperature frequently gets about 5 degrees higher than the set point on the controller before the freezer kicks in. Thankfully the fact that my 5 gallons of wort responds slowly to temperature changes (yes, I monitor the temp of the wort separately... I know... Geek) means that I can make the adjustments and pretty much let the controller do it's thing. I just do not know if I would be comfortable using the controller without knowing the ambient temp in the freezer or the core temp of the wort.
That said, this controller does the job for me and was able to do it for a very reasonable price.
Description of Johnson Controls A19AAT-2C Freezer Temperature Controller
Use this handy controller to regulate the temperature in your freezer between 20 - 80F . Great for turning a chest freezer into a keg refrigerator. Strictly a mechanical thermostat for cooling only, it is simple to use and economical. It operates with a gas filled probe on a 6-foot capillary tube. When the gas contracts or expands in the probe, it triggers a mechanical device inside the control which turns the power on or off. There is no probe temperature readout on the dial, so keeping a thermometer inside the refrigerator is highly recommended to keep track of the actual temperature. On most refrigerators, the controller will allow a usable range of 37 to 80 F, while on freezers, the controller will be able to reach its full 20 to 80 F range. *Keep in mind that if you use it to control a refrigerator, you will lose the use of the freezer compartment for food storage, as it will not stay cold enough for safe frozen food storage.
