NOTE: The Manual Speed value will follow the compressor speed command while Speed Control = Auto. When Speed Control
= Manual, the Manual Speed set point can be set to the desired value. Manual Speed set point should have a maximum
value equal to the Maximum Compressor Speed set point for that circuit.
Fan Staging Deadbands
Fan Stage Deadband settings will only be visible if Fan VFD Configuration is set to None or 1st Fan VFD. The condenser fan
staging deadbands have different default values based on the Fan VFD Configuration set point. When that set point is changed, a
set of default values for the fan staging deadbands is loaded as shown.
