[Equest-users] Minimum Fresh Air AHU

[Carol Gardner]

Andrew,

Create a Dummy space, very small 1ft x 1ft x 1ft with no load and then a
Dummy Zone for it and use this for your zone. I would not use Multi Zone but
rather PSZ if you are supply the fresh air at a constant volume or PVAVS if
it is supplied at a variable volume.

Best,

Carol
