I see that Bezzera make a HX machine with a PID. Can anyone explain to me how that works?
Does the PID monitor the boiler temperature - which is usually the steam temp in a HX, right?
How then is the group head temp regulated if there isnt a pressurestat?
Ive done a search of old threads for the last year but couldnt come up with an answer - although some people mentioned in passing that a PID wouldnt really be necessary on a HX machine?
Yours in confusion,
