Morning Folks,

I'm trying to model an Air cooled VRF system which has a mix of various hydronic heating at the space/zone level such as trench heating and baseboard heating. 3 Dedicated OA systems handle a portion of the buildings ventilation heating load, the zone level VRF's do the remainder and the trench heating and baseboards deal with the infiltration and fabric heat losses.

The issue I am having is that the auxillary heating row on the coils Tab is not accessible for  the VRF system.

How do I correctly model this set-up?
