Sets the amount of time that the setpoint will remain boosted
after lag pump is de-staged.
SP Boost Time
Sets the system setpoint increase each time a new pump is
brought online.
MP Setpoint Inc Pump 1: Setpoint
Pump 1 + 2: Setpoint + P3-12
Pump 1 + 2 + 3: Setpoint + 2 x P3-12
Sets the system setpoint decrease each time a new pump is
brought online.
MP Setpoint Dec Pump 1: Setpoint
Pump 1 + 2: Setpoint - P3-13
Pump 1 + 2 + 3: Setpoint - 2 x P3-13
Sets the time used to stabilize the system when a pump is added
or shut down during multiplex operation.
When a pump is added, the stabilize timer temporarily disables
the lead/lag functionality for the programmed time to prevent
M-Stabilize Time
pump cycling.
Function is active in contactor multiplex mode (P1-01 = 1).
Time pump protection and lead/lag control is suspended during
stabilization time.
Sets the High Feedback level that will trigger a quick de-stage.
High FB De-stage The quick de-stage uses an internal 2 sec delay.
A setting of 0 disables this feature.
Sets the Low Feedback level that will trigger a quick de-stage.
Low FB De-stage The quick de-stage uses an internal 2 sec delay.
A setting of 0 disables this feature.
Stage Sel Mode Sets the method of staging for the pumps.
0: Sequential 0: Sequential
1: Stop History 1: Stop history
Destage Sel Mode Sets the method for removing contactor pumps.
0: LastInFirstOut 0: Last in, first out (LIFO)
1: FirstInFirstOut 1: First in, first out (FIFO)
Precharge LagSel Selects which of the lag pumps can come on during a pre-charge.

Sets the length of time that the lag pump specified in P3-40 is
Precharge Lag Tm energized.
Determines whether the lag pump set in pre-charge (P3-40)
Post PreChg Lag
turns off or maintains its state when pre-charge is completed.
0: Turn Off
0: Turn off
1: Continue
1: Continue
Sets the length of time that the drive is in the pre-charge mode
PreChg Lag Delay before the lag pump set in P3-40 is energized.
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
When P3-02 is set to 0 and a total of two pumps are running, the
last pump (Pump 2) that was brought online will be shut down
by opening the dedicated mult-function discrete output
(H2-0o = 80 to 84) when the output frequency falls below the
P2 Shutdown Freq level set in this parameter for the time set in P3-09.
When P3-02 is set to 2 and a total of two pumps are running, the
last pump (Pump 2) that was brought online will be shut down
by opening the dedicated mult-function discrete output
(H2-0o = 80 to 84) when the delta feedback (setpoint minus
feedback) has exceeded the level programmed in this parameter
for the time set in P3-09.
