Hi Cindy, Having just installed a PID in my B2 today, I can say with confidence that the PID is reading temp at the boiler. It has a thermowell in the top of the boiler and a short wire to the PID unit.
You can read about many experiments with temp probes inside the PF, etc. on homebarista and I think some here too. The idea with our machines is that the group will be close to the temp of the boiler (thermosiphon), but you'll still get some cooling. You'll find that it's relative though--you'll raise or lower the boiler temp until you find one that you like, so the actual temp at the PF won't matter--you'll know what works for your taste and coffee. Does that make sense? It is an interesting subject though. best, bmc On Mar 12, 2011, at 7:48 PM, Cindy Goddard wrote: > Hello everyone! > > Just placed an order from WLL on Friday as well as a Baratza Vario > grinder.
