Hi Maria and Nick,<br>
<br>
Thanks, the reports make more sense now.. There is no under-heating
or under-cooling hours so that answers my question "if the heat is
getting to the zones". My SS-A report shows that my systems are
working fine even in the zones the LS-A reports zero load (internal
gains and like). <br>
<br>
Thanks a lot for taking the time to clarify this non-issue. I have
breaking my head on this model that seems to work just fine :)...<br>
<br>
Best,<br>
Sheldon<br>

<p class="MsoPlainText">Loads in LS-A report (and any other
“L*-*” report) account only for envelope and internal gains,
but not HVAC-related parameters. I wouldn’t expect these loads
to change as you adjust reheat or thermostat setpoints. You
should check SS-A report instead. The Detailed Simulaiton
Reports Summary that Nick suggested below is a great resource
for interpreting reports correctly.<o:p></o:p></p>
