how is the loop for the WSHP's being conditioned/tempered? The WSPH's can trade heat to/from the loop, but ultimately there is centralized equipment that would need to maintain the loop temperature. That may/should dictate the navigation thru the HVAC system map.
for example - if you have a dry cooler (not a fluid cooler) and an electric boiler(s), those are Air cooled condenser and electric heating. This should make SZ Systems 9's, and MZ system 3's.
Conversely - if this is a fluid cooler - it may depend upon if the capacity of the boiler or the total heating capacity of the WSHPs is larger. (90.1-2022: 12.5.2 j. 2 > mixed fuel heating > largest capacity). If the HPs are larger then it's System 6's. If the boilers are larger it ends up being 5/1 (electric) or 7/2 (fossil fuel).
