Duct static pressure control
During plant modes 1 to 6, the SPA_StatPressControl will be released as soon as the input "FanEnableSig" becomes true (=1). The setpoint for the SPA_StatPressControl is defined by the datapoint "DuctPressSp", while the proportional band and integral time respectively are defined by the parameters DSP-02 and DSP-03.
The next figure shows the internal control signal of the SPA_StatPressControl in relation to its setpoint and proportional band.
