Having just gone through my little exercise with the controller replacement, I am beginning to think about how the temperature offset and the set temperature relate to this issue of brewing temperature. I noticed that Ira and Barry have different offsets (-5 for Ira and -7 for Barry, I believe). Am I correct that one machine showing a 95 C degree temperature on the LCD and a -5 offset has a boiler temperature (and, therefore, grouphead temperature) that is theoretically 2 C degrees lower than one that has an offset of -7 C? In other words, should one talk about a "corrected" temperature (corrected for the degree offset) when one talks about the temperature rather than just asking what to what temperature someone has set their machine? Am I missing something here? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Brewtus" group.
