I recently upgraded to v14 firmware (HM 4.1) and am finding that my HM is now, on occasion, overshooting and simply refusing to turn the fan output off. And I don't mean in a "I built this thing wrong" kind of way -- I'm talking software.
For example, I currently have a setpoint of 250F. At 255F and climbing, it continued to blow the fan..........in fact, it was still blowing the fan a moment ago at 262F and climbing (12F above setpoint, with no end in sight).
When I say "fan output", i'm referring to a substantial 30-40% output. I don't understand why it's happening, because I've never experienced this prior to upgrading. I'm luckily able to get it to cut off if I feed in a substantially lower setpoint temp. So in my current situation, in order to get it to shut off fan output for 250F setpoint / 262F actual, I had to set it to 230F and at that point it finally went to from 30% to 0%.
Anybody else experiencing this? I'm stumped.
