OK. Good news--back in business thanks to IRA, ROB, and BARRY. It
had been years since I had adjusted the temperature, so I re-
acquainted myself with the literature. Pressing the Set button for 5
seconds is the trick.
So once I was into the temperature-setting mode, I set the unit to 60
degrees and all functioned well. I was not careful about measuring
the time on this leg, but it was about 8-10 minutes. The temperature
overshot 60 to 63, then dropped to 59, when the tiny red On button
lit, a slight "click" was heard, and the temperature cycled again
through 63, taking about 2-3 minutes. I then re-set the temp to 90
degrees, where the same cycling occurred. (For those who are
interested, at 1 minute, the temp was 69; at 2 minutes, the temp was
76; at 3 minutes, the temp was 83; at 4 minutes, the temp was 91; at 5
minutes, the temp was 94; at 6 minutes, the temp was 93; at 8 minutes,
the temp was 90 and the heat request light clicked on.) I then raised
the temp to 95 and the cycling overshoot is up to 99.
My wife just brought me a cap, and we are both SO VERY grateful to all
who at least stopped by to see if there was anything that they had to
contribute, but especially to IRA and BARRY for their info and
support. It is truly appreciated. Thanks also to Todd who responded
by email to some other problems I had.
(I have to say that my fantasy about the Brewtus, which I have had for
4+ years, has been shattered, as I have discovered how much thermal
variation there is. I had not realized that Expobar set the
controller to conceal the overshoot temperature.
I will probably start a thread on temperature, as I have to relearn
about my machine. We had always had it set to 95 degrees, and we will
start there, but I had not realized how close we always were to the
dreaded E1 error code!!)
