<font size=3>I used Botota for the weather file. For system UMA
102, I changd the cool control to Warmest and Heat Control to coldest and
changed the reset priority to Temperature First. The heating energy
is cut in half. Do that on all the systems and you man chop all the
heating in half. <br><br>
The danger of self-sizing with program default is you don't know what or
why the results don't appear correct. <br><br>

<b>Subject:</b> [Equest-users] stumped re. excessive heating<br>
I have a proposed building in a tropical climate with CHW cooling
and <br>
no heating. Per ASHRAE I’m installing electric heat in both the
Baseline <br>
and Proposed models. The heating in the Proposed is double what it is
<br>
in the Baseline. Worse yet, I am getting the following warning:<br>
<br>
**WARNING**********************************************************************<br>
ZONE EL1 East Perim Zn (G.E19) <br>
might have insufficient heating capability.<br>
Check that the SYSTEM or ZONE HEATING-CAPACITY plus this<br>
ZONEs BASEBOARD-RATING is adequate to maintain the ZONE<br>
specified DESIGN-HEAT-T for the calculated peak ZONE load<br>
(see LS-A or LS-B for the ZONE peak load.)<br>
<br>
SYSTEM UMA
102
<br>
which supplies the above listed ZONE, has a design heating<br>
coil exit temperature, HEAT-SET-T,(plus any zone reheat)<br>
below its MAX-SUPPLY-T or the ZONE DESIGN-HEAT-T, which<br>
might account for the insufficient heating capability.<br>
<br>
<br>
Does eQUEST overcompensate for an erroneous config for heating such that
<br>
it would behave this way? What should I look for?<br>
<br>
Thanks in advance.<br>
