Hello, looking for some thoughts regarding using VVT style zoning on a variable speed furnace/air handler. Since the motor is load dependent (IE adjusts RPM based on static/resistance to ensure constant volume) how will it react to a bypass damper? I have done a lot of zoning with standard equipment with no issues but these ECM motors have me on the fence regarding trying it out (gets costly after its all installed and don't work). Ive Googled the snot out of it and get recommendations each way. EWC doesn't seem to have a problem with it. Thoughts, experiences?
