Setpoint ramp up/ -down

On initial start-up, after the fan enable signal becomes true (=1), the setpoint of the SPA_StatPressControl will be ramped up, from zero to the value of the desired setpoint, as it is defined by the input "DuctPressSp". When during normal operation the setpoint of the duct static pressure is lowered, a ramp-down function will be effective. Both ramping-up and ramping-down are defined by parameter DSP-01, as shown in the next figure.
