I finished the new temp controller for the ferm chamber. Two Inkbird ITC-1000s. The first unit will monitor and control one fermenter. The second Inkbird will be passive only--just to monitor the temps in the second fermenter when I have two batches fermenting simultaneously. I have always wondered what's happening in fermenter 2, temp-wise. Now I can monitor.
I did a bench test, works ok. One thing I noticed is that the compressor delay function in the Inkbirds is a little flaky. Sometimes the delay works, sometimes it doesn't and the cooling cycle just kicks in right away. When the delay does run, the timing isn't always quite right. To test, I set the delay for one minute. Sometimes the chill cycle starts in about 30 seconds. Other times it switches on in 1 minute.
Kind of a moot point for me as I usually don't use the delay anyway, as I set +/- 1F for hysteresis and the freezer doesn't cycle that much anyway. But it was interesting to run the Inkbird through its paces. I'll calibrate the probes in some ice water before I put it to use.
After I'm done with the batch that's fermenting now and bottle, I'll swap out the old controller for the new one.
