VE IES Apache - Thermostat Changing Vent Minimum?
I have an Apache HVAC problem where I am trying to vary the operating cooling setpoint in a museum yet keep the design-cooling value for airflow fixed, enabling me to study just the effect of a thermostat change rather than a different HVAC system. In Apache HVAC, in the system editor window for a VAV system, I changed the Room Temperature Setpoint from 70F to 75F and left the Design Room Air Temperature at 70F. 
The ventilation and cooling flow is still referencing this Design Room Air Temperature (70F) in the other tab as well, showing me the airflow peak will remain unchanged.
BUT then, I run the models, and ventilation drops and is no longer a happy on-off schedule. I have tried only making this one change in an exact copy of the working Apache HVAC system and still the same results, ventilation drops.
