Hi,

I'm trying to specify separate, constant CFMs for heating and cooling
mode operation (Ex: 5,000 Heating & 7,500 Cooling).

The system I created is Variable Air Volume which serves multiple
thermal zones.

The Fan Flow Parameter MIN-FLOW-RATIO is set to 1.00. I read this as
the minimum supply CFM during cooling mode.

The Fan Flow Parameter HMAX-FLOW-RATIO = 5000/7000. I read this to be
the maximum supply CFM during heating mode.

The Fan Flow Parameter HMIN-FLOW-RATIO = 5000/7000 -0.01. I read this
to be the minimum supply CFM during heating mode.

But from the hourly report the CFM supplied, defined by SUPPLY-FLOW =
7,500, is the cooling quantity during heating mode when I would have
expected it to be 5,000. As far as I can tell no flows are specified at
the zone level that would override it. Any thoughts on things to look
at would be greatly appreciated.

Thanks, Todd
