IDD OutdoorAirSystem:EquipmentList limits number of zones that can be connected to HtRcvry #153

Open joesinger12 opened 1 year ago

The IDD definition for OutdoorAirSystem:EquipmentList limits the number of objects that can be listed to 9, one of which is typcially the OutdoorAir:Mixer .

When using the new method for zone specific EAHR that creates multiple heat recovery objects for each zone exhaust fan (via ThrmlZn:ExhHtRcvryRef), ithe current IDD structure will limit this to 8 connections.

The solution is to add additional fields to the IDD; example attached expands it to be 21 connections. Numbe of connections needed should probably be in the range of 50-100 to not run into limitations for large lab models.

KB has already made necessary changes to OS translator on 11/3/2021.

Assuming this was included in current OS build for CBECC, it should translate and can be tested with IDD updates.
