<p class="MsoNormal">It appears that the WSE “chiller” was changed in the beta of DOE-2.3 included with eQ build 7173. It can/will now operate to augment the other chillers (“integrated”, “series”), instead of turning off when its capacity is inadequate to
meet the loads (“non-integrated”, “parallel”).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, the world is full of non-integrated WSEs, and despite certain prescriptive codes, there is still a need to evaluate them for new construction. I tried some Equip Ctrls and Load Mgmts, but these attempts resulted in either simulation
errors (inadequate capacity) or the attempted “non-integrated” WSE operating when I didn’t want it to. In any case, there may be periods when operators disable WSE operation, so if a CHW EC list does not include the WSE, it should not come on.<o:p></o:p></p>
