Thought I'd share a tip for addressing unmet heating hours in VAV
systems using eQUEST 3.64.

eQUEST 3.64 adds the HMAX-FLOW-RATIO keyword in System -> Fans -> Flow
Parameters. The default value is the greater of the fan MIN-FLOW-RATIO
and 0.5, but this value is determined by the program and you don't see
it when you look at the Flow Parameters tab. Entering a value of 1.0
corrected an unmet heating hours problem for me that appeared when I
opened a model in 3.64 that I originally created in 3.63. This works for
both VAVS and PVAVS system types.

Regards,

Bill
