where to check the zonal DCV system form at cbecc com

edit

Hi I have one cbecc-com model 2016 and each thermal zone has small heat pump. There is AHU for each zone as well and it has DCV system for every zone. Should I check the form of DCV system under the entire AHU or small heat pump zone. I was trying to DCV form under the zone, but there is no form can be checked under thermal zone directly Thank you
