Hello eQuest community
I?ve been using eQuest on a basic to moderate level for a while, and am
starting to get into more detailed modeling.
What I have now is a building with boilers in a basement that get fresh air
from a 100% OA supply fan. The fan is interlocked with the boilers so that
it only supplies air when the boilers are burning fuel. The fan also has a
hot water coil to keep the air at a minimum temperature to prevent thermal
shock of the boilers.
I?m pretty sure I?ve got the heating figured out, but how do I link the fan
schedule to the boiler operation schedule?
An answer to this will definitely help in figuring out interlocking other
equipment in eQuest
Thank you all for your help!

Shawn,
If you select a boiler TYPE of "...w/ draft" you will see default values for the boiler ELEC-INPUT-RATIO and EIR-FPLR curve. This simulates electrical consumption coincident with boiler operation. You could calculate an EIR based on all fan power, controls etc. associated with your boilers. I haven't plotted the default "Draft-Fan-EIR-fPLR" curve so you might take a look at it and make changes based on your particular boiler plant.
