The biggest change in this update is the prototype docs and tags for chiller plants. There is a new Chillers chapter and about 25 new tags. The new chapter defines four new equipment types:
Given chiller plant complexity I wanted to take the discussion from topic 35 and just get a prototype flushed out. I don't consider this final, nor complete. But it is hard to review something this big without a clean,fully flushed out docs.
So please review what I've done so far and provide feedback.
Couple of comments/questions:
I did not specify the most important point in chillers and that is their runtime capacity, I will start a new topic for further discussion
I did not even touch pumps, I had them as points originally, but then we started discussion around them as equips. My suggestion is that with chiller plants done, we can now move into boiler plants and make a final call on pumps between these two use cases
I only specified setpoints which are commonly used (even though technically you could match a sp with ever sensor); if you find that I missed a common setpoint let me know
In/Out vs Sensor/Command
Per discussion topic 25 I have renamed the tags in/out to sensor/cmd.
EquipRef
Per discussion topic 33 I made equipRef required on all point entities. I also specified use of equipRef on an equip to model nested equipment.
Elec Meters
Per discussion topic 7 I have renamed elecKw/elecKwh to kw/kwh and added several new points for volt, current, power factor, and freq.
New Downloads
Per user suggestion from @John Sublett I have added machine readable downloads for the point listings for each equipment type. See Downloads tab. These are plain text files that list each point on a single line as space separated tag names. A couple more complex point listing have headings indicated with with the line start "**".
Forum Enhancements
I've enhanced the forum to make it easy to link directly to a tag definition by quoting it with backticks:

Will become a link to the chiller tag.
