4.3
Override of secondary set point in cascade control
If cascade control is active (with VAV for example) or if the setpoint is controlled by an input, the user can manually select
the set point (the loop is then changed to constant air volume mode). This function is helpful for tuning the VAV system.
While the secondary loop is displayed change the set point with UP/DOWN. The hand symbol appears. Change setpoint
again to cancel cascade override. The hand symbol disappears.
With cascade control or if the setpoint is controlled by an input, manual override of the setpoint can be deactivated.
This is defined by the technician in the controller settings.
If manual override for cascade controls is deactivated, the secondary control loop will not be shown on the display.
