<div>Dear all,</div>
<div> </div>
<div>I have a LEED model, after switched the version into v3.64 from v3.63, a lot of insufficient heating warnings like below are reported, the percent of hours outside throttling range is also rise, while the model has been adjusted to no warnings and
within 300hours in v3.63, it's a VAV system with electric cooling in summer and purchased heat in winter.</div>

</font> mentioned there are enhancements for "insufficient heating capability" in V3.64, I tried increasing "heat sizing ratio" and "throttle range", but failed, can anyone give me some guidance to fix this issue ? I wish can benefit from soem new features
in v3.64, but it's close to the end of project, there is little space to play.</font></div>
