<p class="MsoNormal">I looked at your file. When I get these types of unmet errors, the first thing I do is set the max flow for heating (under the fan flow parameters) to 1 or whatever ratio is allowed - I think the eQuest default is 0.5, which probably is
too less for cold climates. If this does not help, I normally look at the min flow (reducing it if possible helps). Other is to look at the zone design cfm - usually reducing it helps - but reducing it too much results in cooling hours unmet. For LEED I try
to get each zone unmet below 50 -so start with the highest unmet zone. Sometimes I end up with a combination of all the above.<u></u><u></u></p>
