Using <i>equipment controls</i> you can specify when the chiller
and when the chilled water meter satisfy the load under different
load conditions. However, as you are looking for seasonal control,
you will need to set up a <i>load management</i> for the chilled
water loop. Load management lets you specify which equipment
control strategy is in control based on a schedule, loop load, zone
temp or OAT. So you will have 2 equipment controls - 1 where the
chilled water meter serves the loop and 1 where the building chiller
serves (you also can have a combination). You will also have a load
management which points to the chilled water meter equip control in
the summer (based on a schedule or OAT) and to the chiller equip
control in the winter.<br>
<br>
I do not believe you can have multiple chilled water coils in eQUEST
AHUs.<br>

<p class="MsoNormal">I have a building that uses an on-site
chiller during the summer months, but uses chilled water from
a central plant for small dehumidification loads during the
winter and shoulder seasons. Both sources of CHW serve the
same coils in AHUs. Does anyone know how to model this????<o:p></o:p></p>
