HeatingSystem/CoolingSystem vs. Terminal - Note Clarification

[JacksonJ-KC]

There is some confusion currently stemming from the wording for 3 of the Terminal data element notes:

Current wording in question:
"System configurations that typically are at the zone and include a compressor (such as packaged terminal air conditioning, packaged terminal heat pumps, window air conditioning units, and water loop heat pumps) should be reported in the schema using HeatingSystem and CoolingSystem. Systems that include gas or electric furnaces should be reported in the schema using HeatingSystem. System configurations that are at the zone and only include fans and coils (such as four-pipe fan coil, two-pipe fan coil, radiant systems, baseboards, and chilled beams) should be reported in the schema using Terminal with the chilled water and hot water systems described in the cooling_source and heating_source data elements (and any other relevant Terminal Data elements). Evaporative cooling systems should be described in CoolingSystem. Passive diffusers with no coil or fan should be described in Terminal."

Suggest changing this note to remove any opportunity for interpretation around what "at the zone" could mean, and have the location of a system's heating/cooling capacity (HS/CS or Terminal) be definitive and predictable.

Suggested wording:
"System configurations that typically are at the zone and include a compressor (such as packaged terminal air conditioning, packaged terminal heat pumps, window air conditioning units, and water loop heat pumps) should be reported in the schema using HeatingSystem and CoolingSystem. Systems that include gas or electric furnaces should be reported in the schema using HeatingSystem. Distributed systems where each zone is individually served by dedicated fans and/or coils (such as four-pipe fan coil, two-pipe fan coil, radiant systems, baseboards, chilled beams, and VRF indoor-units) should be reported in the schema using Terminal with the cooling and heating systems described in the cooling_source and heating_source data elements (and any other relevant Terminal Data elements). Evaporative cooling systems should be described in CoolingSystem. Passive diffusers with no coil or fan should be described in Terminal."

Also note my suggestion to include the VRF system in the list of examples for system types that would be described at the terminal. This is a common system type that I feel should have explicit directions in case of confusion.
