Auxiliary Pump De-Staging (OFF)

The de-staging of the auxiliary pumps 2 and 3 will occur in the reverse order of the staging process described previously.

The de-staging of auxiliary pump 3 occurs when the difference between the system’s feedback level minus the setpoint exceeds the value

programmed in the Shutdown Pump Delta Level (P3-05) for the time programmed in the Add Pump Delay Time (P3-04).

The de-staging of auxiliary pump 2 occurs when the auxiliary pump 3 is de-staged and the difference between the system’s feedback level

and setpoint exceeds the value programmed in the Shutdown Pump Delta Level (P3-05) for the time programmed in Add Pump Delay

Time (P3-04). Refer to Figure 132. for the de-staging of the auxiliary pumps 2 and 3 using the “feedback level” control method.
