I'm contemplating installing a PID on my ECM GIOTTO. Has anyone done it? should I bother?where the results good? what's the best spot for thermo sensor? Thanks

The ECM Giotto is a HX machine, isn't it? A PID, while being feasible, doesn't make much sense on such a machine, because the boiler is on steaming temperature and you can't influence brewing temperature directly. So, my advise is to safe your money.

Due to the way a HX machine works, you will NOT affect the brew temp in any useful way but if you have money to burn and just have to work on something, you probably will not harm your machine, you just will be controlling your STEAM temp to a tighter dead band. I am going to try putting one on a HX machine that needs a Pstat but I have no expectation of it doing anything to the brew temp, it is just a less expensive way to get the machine running again as I have a PID setup and I would have to buy a Pstat. YMMV!
