Upper limit for second temp probe #45

Closed ThroughTheLookingGlass closed 9 years ago

ThroughTheLookingGlass commented 9 years ago

First thank you so much for all that you have done! I have made a few of the dual probe STCs and couldn't be happier with them! One thing though, I find it hard to use them to control overshooting, since fermentation is sometimes more intense than other times. I feel like my biggest concern is making sure temps don't go OVER an upper limit, on either probe. Too high of temps cause off flavors, too low and they drop out, since my profiles are always slowly raising the temp to keep them active longer, I push towards the yeasts upper limit fairly close so I am MUCH more worried about raising the temp of the outside or inside of the carboy too high than I am of the temp being too low. I find myself wishing I could set an upper limit for BOTH probes that would turn off the heater and/or turn on the refrigerator if either probes go over a certain limit. I think Upper and maybe Lower limits for the both probes as a whole would be very useful. I m new here and could not find a way to contact you other than this. Not exactly an issue I guess, just wanted to contact you.

Hi! Thanks! It is always nice to hear :)

The main discussion of STC-1000+ takes place here: http://www.homebrewtalk.com/f258/stc-1000-a-464348/ So please feel free to ask questions et.c. over there.

The idea of temp probe2 / hy2 is to limit how far off the ambient temperature may deviate from the setpoint. This should work equally for heating, So unless I am understanding you wrong, it already does what you are asking for,

That is true, I guess I may have just been lazy because I don't mind the temps being far off during active fermentation, so I set it to about 5 or 7 degrees 2nd probe hyst, but then when I raise the internal temp to 70 or 71(and I don't want either of them higher than 72) later in fermentation when I do not want them far off, I can manually lower the 2nd probe hyst. Thanks though, every new update is great! Maybe one day I will tackle the temp tracker, but that looks a little harder than just adding a 2nd probe..

So far there is no person or company even close to this level of temp control, and at the price of an stc and some additional parts! Can't say thank you enough!

Will check out that forum you posted, thanks
