[Equest-users] Gravity Relief Vs Power Relief

[eric wang]

David,
 
My understanding is that there is no difference between the relief fan and the return fan if the kw/cfm and the return CFM are the same from the perspective of energy consumption.
Please correct me if I am wrong.

When I specify the return fan as relief within the wizard interface, it
dose not show a return fan being specified in the detailed interface.
How dose the detailed interface represent the return fan as relief
within the detailed interface when it has been specified in the wizard
interface?

In the wizard, you can specify whether the return fan is relief, return
or
none (gravity relief).  Same in detailed interface.
