Thermostat Inkbird ITC TB 310 Temperature Controller Pre-Wired Dual Stage Digital Outlet 12 Periods Timer (ITC-310TB)

I really don't trust any review that says this is easy to uses. The instructions make mud look clear. The human factors of the display are actually inhuman factors. If you are not good with decryption of doubly encoded messages, skip this one. The text is in poor English and the symbols used on the screen are not the ones used to describe the operation of the device. Fortunately (sarcasm) they provide a "magic decoder ring" for the symbols. The incredibly bad language is up to you.A few hints: 1. The "SET" presses only last 10 seconds, so you better lay out all the steps first or you will have to scroll through the menu numerous times. 2. The "Note1" etc. are references to Paragraphs 5.1 through 5.7. 3. Read paragraph 4.2 carefully. Here is a translation: 4. The parameter AT, which looks like a A with a broken E on the screen, should be set to one or all the parameters are lost if power is lost.4.2 How to Set ParametersPress and hold “SET” key for 3 seconds to enter into the parameter setting mode, upper window will display the code TS (see: section 5 table) will display, the lower window will display the values being set. Press “SET” key to page down the menu tto the code you want to change, press up/down arrow heads to change the current parameter values. After entering the correct value, press and hold “SET” key for 3 seconds to save the parameter and return to the normal displaying mode. Each item set will require traversing the menu again. If there are no key presses for 10 seconds, the system will quit and return to the normal mode without saving the parameters modification.Update: Up from one star to three. It works well once you figure out how to use it. Persistence is the key. I have been using it for five days and getting better and better results. I found that having low limits on the HD and CD parameters is important for cooking in a crock pot. I moved these down to 2 degrees F and my steel cut oatmeal is turning out much better. My credentials: 56 years in the computing business, 44 patents, and I built one like this (no timer) from scratch a few years ago for my son.

After testing the unit and using it on beer fermentation, the unit operates very well. The frozen water tests came out from 32.4 to 32.8 which is very good. I tested the different programmable step temperatures and it worked fine. Remember if you want the final step to be held a long time, enter a large value that you will never reach such at 999 days. The reason for this is after it cycles through all the steps it will shutdown the unit on the completion of the last step after the specified hold time. This could be bad if you are fermenting something.The only strike I fine against the unit is you can't wait too long (about 10 seconds) when setting the unit otherwise it will lose your new setting and go back to original function. The program able function names could be done better also.

Works once you figure it out, but instructions aren't very good. The manual sucks and is in a super micro print so go online to their site to save your eyes.The first step in programming (per the manual) it is to set the time and date, but this actually can't be done so you'll spend about 10 minutes trying to figure out why your following instructions that don't work. I can only guess that they copied info from another devices manual not realizing they included non working instructions. Just skip that part (and frustration) and move on to the next confusing part of interpreting symbols. Once you figure it all out though, it does what you're wanting it to.

Bought this on some good review. First two times, seemed to perform well. Redundancy in temperature measurement and is was close enough for what I needed, temp control of a fermentation chamber. 3rd time out, after a 12 hour day with my son, went to the garage and saw the controller had gone belly-up, electronically. Weird symbols in the PV that were nothing showing in the manual or any research. And hitting the set button, holding forever was useless, nothing popped up in the PV. Magically, went from F to C in front of our eyes. Had to go back to an old Johnson to try and save the beer, rocking at 75, way too hot. Went home, next morning for kicks, tried the Inkbird and it worked! A bit leery, nevertheless hooked up again because while daytime temps are 64-66, nighttime is getting as low as 49. Went back first thing next morning and....Inkbird back to that weird couple symbols in PV; busted. I don't know that anything transpired in cooler, actually.I can't give anything but the lowest evaluation. I'd prefer to have less whistles, and have the ability to, um, control temp. It's basic function, which it failed miserably, at the worst possible time.

Excellent build quality with lots of options for customization, and to top it all off it's super easy to program! My thermal probe connector seemed a bit loose so I contacted Inkbird and they solved it right away! Great customer service, they stand behind their products 100%. I've been testing this unit for almost a week now at various temperatures and its holding my fermentation profiles perfectly! Now I can brew my first lager this weekend with total confidence!

Set button quit working after 1 month. Inkbird kindly replaced the broken unit and I’m back up and running.

Been using this to control the temperature for my keezer for nearly a year now and it has worked flawlessly. Getting many people asking how I'm able to control to refrigeration temperature and I simply point out this little gem. Would strongly recommend.

The programability is key... works a charm for my home brew fermentations. I have two installed on upright freezers converted to hold conical fermenters. The ability to set key fermentation temperature programs increases my control over yeast character. So far, has been very reliable.

Works well to control heating and cooling for plant propagation. It takes a moment to figure out the programming but then seems very simple and easy to adjust. This is a wonderfully simple concept to control heating and cooling. This would be five starts except a unit failed after about nine months (sensor temperature moved out of range). Fortunately the vendor responded immediately with a replacement. I had already purchased another one of their units and wouldn't be without them.

I upgraded to this unit to control my germination bed temperature for sprouting seedlings and germinating spores. I run the external probe along the bottom of the bed where my spawn jars or seed bags are to ensure it keeps the area to 80F where I want it. So easy to use and set up. I have an inkbird bluetooth sensor in with them to monitor the area from my smartphone

Temperature seems to be accurate so I had no issue with that. The device is pretty much plug and play. I use it for my incubator at home and it works flawlessly. The menu doesn't seem very hard to maneuver so I'll give that a thumbs up as well.

Setting up a small fridge to help with beer fermentation was never easier. Inside I put the Lasko personal heater and run a McDonalds straw for CO2 purging at the bottom. Given I had an extra Netatmo room sensor, with CO2 detection, I put that inside the fridge too. So I have control and historical indicators for temp/CO2. Easy to see when the yeast begins to quiet down.

Temp cord to short could be a few feet longer
