VFD Type
Select the appropriate VFD Type for this specific job.
The available options are None, PowerFlex, and Other Mfg.
Selecting <PowerFlex> assumes you are using either the PowerFlex 400, PowerFlex 70 Enhanced, or
PowerFlex 700 Vector drive.
All drives types use 4-20mA command and feedback.
VFD Bypass
VFD Bypass should be selected “Yes” if VFD Bypass is on this specific job.
An Air/Fuel curve must be configured for each fuel while in bypass mode.
VFD bypass allows the boiler system the ability to keep the combustion blower motor running even if the
Variable Frequency Drive is taken out of the loop for any reason.
