A Look At: ITC-1000 Temperature Controller + PDF Manuals & Build Instructions

ITC-1000 Temperature Controller

Here’s at the ITC-1000.  First, some background… The STC-1000 is a very popular homebrewing temperature controller.  One caveat of the STC-1000 (for some) is that the vast majority (maybe all?) display in Celsius only.  Yes you can do some firmware re-flashing and such things, but as far as off the shelf units, the vast majority read in Celsius,

Enter the Inkbird ITC-1000… It’s 110 V, Dual Stage (can control both heating and cooling output), has an alarm to indicate sensor failure or high temperature and… it displays in Fahrenheit… finally!  It’s also said to be more user friendly than the STC-1000.

The STC-1000 was already a great controller, arguably the best value in temperature controllers.  These improvements seem to make a great thing even better.

    Does anyone know if the itc-1000 starts up in compressor delay? What I mean is if the delay is set to 3 minutes when it is unplugged and then I plug it in, will it wait 3 minutes before turning the cooler relay on?

    Is there a way to calibrate the unit.
    We recently had some bad thunderstorms come through & my unit starting reading higher than the actual temp of my aquarium – so the unit went into ” COOL ” mode .
    So I wonder if it can be calibrated – or if I should just think about replacement .
    We have a ITC-1000 .

    Thanks in advance,

    Hi I put a 10 amp fuse between my heater element and the number 6 connector . I have the neutral going from connector 2 to the plug and to the other heater element wire. I have connector 1 and connector 5 and the hot wire from the plug together. It keeps blown the 10 amp fuse. I put the fuse here because I sprung a leak and shorted the other inkbird out blown the little brown box connector in the inkbird. I have pulled out my heater element and have found no leaks so I should not be shorting out the system. Why would I continue to blow the 10 amp fuse?

      Hey Gordon! I’ve emailed Inkbird and asked them to answer. I’m no electrical expert and I’m guessing they’ll be able to help you.

      I *think* (but I’m not sure) that the probe is submersible. It appears to be watertight and I believe others have indicated that the STC-1000 probe is submersible. I’ll also give that a good test when I put mine together.

      I’ve had an STC-1000 sensor that looks like the one pictured (black rubber) sitting in a 12oz bottle of lightly bleached water for 3.5 years now and it still works. Put electrical tape over the top so water does not evaporate. Maybe I should change the water.

        I have my probe in cheapskate vodka, tightly capped so it doesn’t evaporate. I switched to vodka after The Great Freeze of 2011 when I was lagering at 34F, and the water froze. Read recently that it’s a better idea to dip the probe in vegetable oil. Doesn’t evaporate, doesn’t freeze, and it has better thermal variation qualities than less viscous fluids. I’ll have to give that a try.

      Hey Steve, Great question. I haven’t done my build out yet, so I can’t tell you one way or the other. I will say that I’ve owned multiple digital temp controllers (including a brewbit model t with .1 deg F resolution) and have never concerned myself with tenths of degrees. Even .3 degrees C = about .5 deg F. I think it’s great that you want more precision, but for me… I’m happy with 1 deg F. Having said that, maybe someone else can chime in on the ITC-1000 and if not, I can certainly let you know when I finish my build.
