[Equest-users] DOAS and dummy zones

[Matthew Higgins]

Xavier - I've recently used the "Heating / Ventilation System" Type, 
assigned it to a mechanical chase zone, un-installed the heating element 
of this system, turned on the Economizer and ERV functions, and in 
assigned the individual zone system's OA as supplied by this "Heating / 
Ventilation System."

But be cautious of what the .SIM report says under the ATTN tab for the 
equipment...
