error msg: loop - no primary heating equipment attached

Good Morning -

I am working on a 65 story building in eQuest 3.64. The building is cooled
by Standard VAV units (primary cooling equipement is chillers) heated by
perimeter baseboards (steam boilers).

The first 6 floors of the building have perimeter induction units with no
re-heat. For this I have created a different loop (linked this to the
primary heating loop). This loop is called the Circulation Loop 5 in my
model. I assign this loop to the baseboard loop in the air side HVAC
parameters.

When I run the simulation I get the following error:

***ERROR***********************************************************************
Loop: Circulation Loop 5 has no attached primary
heating equipment.

I could not find anything in the archives directly to tackle this issue.
Not an expert in HVAC and hence need your advise.

Thanks in advance.

If Circulation Loop 5 is attached to the primary heating loop as its source of heat, then I believe you need to designate the Loop Subtype as ?Secondary?. See Screen Shot:

Nathan -

I have tried this before and gives me this error message and restores the
settings:

Any thoughts.
