Hello All,

I am trying to optimize an enthalpy energy recovery wheel in a VAV AHU with an economizer. The AHU design allows for full bypass of the enthalpy wheel in economizer mode - I would like to model this static pressure reduction in eQUEST.

Currently the wheel operation is set to "When Minimum OA" to take advantage of economizer operation. Can anyone confirm if eQUEST bypasses the wheel when it is "off" in this operation mode? If not, is there a way to control the wheel so that OA and EA bypasses the wheel during economizer mode to eliminate the wheel pressure drop.

Thanks in advance for your help.
