These are recommended settings by Dave. It is important to note that unless you can tell something is absolutely wrong with the temp, for example if you pull a medium roasted coffee shot at 93-94°c, get a nice flow and ratio yet it is still way too sour, I would not worry about the temp of water at group head, for 2 reasons. 1. Without a specialized device like Scace II you will get very inaccurate results even with a good instant read thermometer. 2. Elizabeth is a saturated group head and it is as temp stable as it gets for any machine under $2000.
