My CC is set to 0 on P9. I don't know if this is the value that came from the factory or if it has inadvertently been changed.

I was reading in another forum where a guy had set his to 10. 10 looks pretty close when I check my CC1 with my home made scace type temperature device.  MY CC1 definitely runs a lot colder than my V2B when checked with the same device.

Actually, the guy in the other forum stated his was -10. He scaced his to get that number. From what I can see of my own numbers, mine probably needs to be turned to a higher temp, so I guess I need to input a negative number. I am going to do some more testing before I make up my mind what the number should be.

I can't remember but what did P9 do, thinking it was for overshooting but having a brain fart

P9 is the temperature offset.

I ended up setting P9 to -12 for my CC1 V1 machine... but there is more to it than that.

You must pull a 2 oz warm up (you don't need PF in place) immediately before your first shot.... then your actual pull will be within a degree or so of set point for a 2 oz shot. I have not tested a subsequent shot right after... but I will try to do that by the weekend. Also, the machine needs a good 45 minute warm up.

The bad part is I have owned the machine for over 10 months.. I usually did a warm up shot, but I have no clue if the offset has been at 0 all that time or not. I guess that explains why the V2B blew me away when I set it on the counter. My goal is to get my CC1 pulling shots as close to the V2B as possible. I haven't actually pulled a shot with the new settings, but I can almost guarantee you there will be a significant improvement. With the scenario above, I can get brew head water temp almost identical to those on the V2B.

Sorry to shamelessly bump this thread but surely someone else knows what their P9 value is set to???  I am interested to know what the default was on the CC1 machines that were shipped out.

Well, I guess all of you CC1 owners are going to keep the factory setting of P9 parameter a secret... but from everything I have read and my own tests, it should be between -10 and -12 degrees. Since mine was at 0, I am going to assume that I inadvertently changed it at some time when I was programming my brew menus... so a big ole mistake on my part.
