Description

The Inkbird dual stage temperature controller is an easy to use and economical controller that is perfect for home brewing. Inkbird controllers allow you to control both heating and cooling, and set independent differentials for each to keep the exact temperature you need.

The Ink bird ITC-308S controller performs many of the same functions as the Ranco or Johnson but at a more affordable price, making it a great alternative for temperature control.  Aside from brewing uses, this is a great dual relay output temperature controller for cooking (use in a smoker or bbq), home growing (heat mats for seedlings, climate control), or any other DIY project you come up with!

Features:

  • Simple plug and play design with user friendly LED interface
  • Dual stage ITC-308 - control both heating and cooling
  • Adjustable Heating/Cooling differential
  • 1000W max power
  • Celsius or Fahrenheit
  • High and low temperature and sensor fault alarms
  • Can control temperatures of -58° F through 210° F (-50° C - 99° C)
  • Body Dimensions: 5.5 in x 2.7 in x 1.3 in

Brewing friends, I just purchased the Inkbird ITC-308, and I'm using it to control the temperature of a ~7cf chest freezer. I've heard that excessively cycling a compressor on and off can shorten it's life. Does anyone have recommendations for the "Cooling Differential Value" and "Compressor Delay" that will give "good enough" temperature stability for fermentation, but won't wear-out the compressor too quickly?
Robert Garton on Sep 30, 2019
BEST ANSWER: Rubber band the thermo couple to a plastic bottle filled with water. The bottle changes at a more constant rate than the ambient air.
How does this work on a Kezzer?
Donald Palmer on Feb 21, 2019
BEST ANSWER: Very simple. You plug the keezer into the Inkbird controller, then plug the Inkbird into the wall outlet. the allows a freezer to cycle on and off in order to maintain warmer temps than a standard freezer can do on it's own. We use this controller on a mini fridge we converted into a fermenting chamber as well as a huge 14 tap keezer we built. keep perfect temps.
What is the input voltage range for this device?
Freeman Wells on Aug 7, 2020
BEST ANSWER: 120V
Our controller wont hold settings. It keeps going back to defaults. Very frustrating. Any thoughts ?
wilco landzaat on Mar 23, 2019
BEST ANSWER: You probably aren't holding the "set" button down long enough after setting your preferred temp. Here's the relevant note from the user docs...
" SET key: press SET key for 3 seconds to enter menu for function setting. During the setting process, press SET key for 3 seconds to quit and save setting change." This has worked for me. If you release the button too early, it reverts to the previously stored setting.

Does what it si supposed to do and lasts.
I had another brand that was more difficult to operate and failed prematurely. It was cheaper and I believed the adds. You always get what you pay for is so true.

Super Easy Setup, Accurate Temp Control
Installed the InkBird on a 7 cu ft chest freezer and used an older Fermwrap (the better type, with the USA-made Calorique element) on a Fermonster.

Great temp control, set it for +/- 1 degree heating/cooling, taping the sensor to the side of the Fermonster. It's been controlling consistently within the control band. The ability to easily customize the setup is great. Highly recommend this product.

If it fits, wear it!
I've wired inkbird temp controls into all of my cooling chambers. They're factory looking, sanitary, and work all the time. I wanted something simple for a small chest freezer that I use for occasional lagering. I picked this because it doesn't beg for custom installation. It's dirt simple, works great, and was up and running within five minutes of opening the package.

Works great. Instructions are confusing and pathetic however. I recommend you Utube it to learn how to use it.
Something definitely got lost in the translation from Chinese to English. Thanks to the guys who put stuff up on utube.

Consistency in cold stabilization
I make white wine from generally acidic grapes, so I always need to cold stabilize. I try to use Mother Nature's cold, but it's been difficult getting her to cooperate to my schedule. I now use this to maintain a chest freezer consistently cold enough to stabilize but not so cold as to freeze the wine. It's working perfectly!

Not as reliable as other temp controllers
I use my temp controllers on both a small fridge for fermentation a chest freezer for lagering. This unit is easy to use and setup and does an excellent job of controlling temperatures, however, I have had 2 of these units purchased at the same time. The first unit fell from 1 ft and hit the floor and never worked after that. I returned it to MoreBeer and they replaced it. The 2nd unit lasted a little over a year (warranty expired) and then started giving a piercing tone and an Er message.

My previous Ranco lasted over 10 years and my Johnson Controls unit is over 15 years old. With the Inkbird units, you get what you pay for.
