MuddyOne - I’ll quote myself again…. :-)
MediumRoastSteam MuddyOne - Interesting. That’s a possibility for sure. But… Logically speaking, it is not as simple. Because the machine should not heat up the longer it stays on idling, and that’s totally unrelated to the offset value. So you might want to tune/review the PID parameters - I mean, the Proportional, Integral and Derivative values. I have no idea how you do that on this new version, sorry.
My theory: You are barking at the wrong tree. Leave the offset alone. Essentially you are saying that your machine temperature target (what you want to set it to) is 8C (or whatever the unit is) lower than the pre-set programmed. If the pre-programmed offset is 12 (just saying that because apparently the factory default is +2, so group being 14C colder than boiler- i.e.: water in the boiler needs to be 108C in order to reach 94C in the group) is within normality. Yet, you are now setting this to -8 (read: boiler water needs to be 98C in order to deliver 94C at the group) - (if that’s what that is) is most likely throwing your PID controller out of the window and it’s erroring like crazy.

So before you think the offset will solve your problems, think again. If they sent you a brand new control box and that was never configured, it might have some crazy default parameters.
You need to do some research, and find out what good PID values are for your machine. Even if you had to copy them from the old Pro-700. A Google research should give you back what you need, including how to get into the advanced menu of your machine so you can set those up.
