You can turn the exhaust fan around - create a packaged single zone
system with a very small cooling capacity, schedule it off for heating
and set the cooling setpoint the same as the setpoint for the exhaust fan
to turn on. It take a bit of optimizing so you don't end up
increasing the heating load. <br><br>

<dd>Is there a way to model exhaust fans based on temperature or any
workaround? I thought this would be straightforward to do but am going
blank on this - this is for large spaces like atrium, or generator rooms,
attic spaces etc.<br>
