Programming Tip
Lead/Lag Parameters are only displayed when 1.3.1 SYSTEM CONFIGURATION has been set for constant
pressure AND when 1.3.2 MENU COMPLEXITY has been set to Standard or Advanced. More information
on can be found in Section 6.4.
Table 21 – 1.5 Lead/Lag Parameters
DEFAULT [UNITS]
(MIN - MAX)
Sets the number of auxiliary pumps that are connected to the
relays on the control board. The relays will be called for in order,
starting with Relay 1.
Delay before the system will call for a pump to be staged in.
1.5.3 Destage Pump
Delay
$
Delay before the system will destage a pump when pressure is
maintained at 1.1.1 MIN FREQUENCY of the primary pump.
This is the interval for which the system will reduce its frequency
by 1.5.7 – 1.5.10 STAGE FREQUENCY REDUCTION.
This is the interval for which the system will increase its
frequency by 1.5.11 – 1.5.14 DESTAGE FREQUENCY BOOST.
1.5.6 Destage Min
Frequency
$
1.1.1 MIN FREQUENCY of primary pump plus this amount to
destage.
45 Hz
(Min Freq – Max
Freq)
1.5.7 Stage Freq
Reduction 1
$
Reduces frequency of primary pump for the duration of the 1.5.4
STAGE TIME when the specified pump is staged in.
1.5.8 Stage Freq
Reduction 2
$
1.5.9 Stage Freq
Reduction 3
$
1.5.10 Stage Freq
Reduction 4
$
1.5.11 Destage Freq
Boost 1
$
Increases frequency of primary pump for the duration of the
DESTAGE TIME when the specified pump is destaged.
1.5.12 Destage Freq
Boost 2
$
1.5.13 Destage Freq
Boost 3
$
1.5.14 Destage Freq
Boost 4
$
1.5.15 Stage Analog
Lag
$
Allows the system to fall below the control psi by this amount
before the system starts counting 1.5.4 STAGE TIME. Assumes
max Hz.
6 PSI (0-200)
31 GPM (0.1-3,200)
0.6 ft (0-500)
1.5.16 Destage Analog
Lag
$
Allows the system to exceed the control psi by this amount
before the system starts counting 1.5.5 DESTAGE TIME.
Assumes min Hz.
3 PSI (0-200)
10 GPM (0.1-3,200)
0.3 ft (0-500)
$ - Parameters are only visible when 1.3.2 MENU COMPLEXITY is set to STANDARD.
