OPERATION

Before operating the pump for the first time, the pump's internal clock and operational schedules must be programmed
by following the steps in this manual. Refer to Setting the Clock and Pump Address below and Programming Custom
Schedules on page 9, for instructions regarding the programming of this pump for scheduled operation.

Setting the Clock and Pump Address

When power is first connected to the pump the clock
will blink to indicate that is has not been set. Custom
schedules are based on this clock setting, so the clock
must be set first.
1. Press and hold Display for 3 seconds.
2. Use "+" and "-" to choose between a 12 or 24 hour
time format.
3. Press Display to advance.
4. Use "+" and "-" to program the current time.
Note: In the 12 hour time format AM/PM will
display in the bottom right corner.
5. Press Display to advance.
6. Use "+" and "-" to adjust the screen backlight
brightness.
7. Press Display to advance.
8. If controlling pump via RS-485: Use "+" and "-"
to assign one of two pump addresses, then press
Display to exit the menu.
If controlling the pump via digital inputs or from
the drive: Press Display twice to exit the menu.
During a power outage, the drive will retain the clock
setting for as long as 24 hours. If the power is out longer
than 24 hours, the clock will have to be reset. If the drive
has lost the user set time, the clock will continuously
blink until the time is reset.
Note: When power is returned to the pump after
a prolonged outage (24+ hours) the clock will
automatically set itself to the Speed 1 start time, blink
and advance. The pump will also run the associated
schedule from that start time.

daily turnover for a typical pool. See Table 2 for default
schedule.

Table 2
The default schedule will operate as follows:
1. SPEED 1 will begin at 8:00am and run at 3000 RPM
for a duration of 2 hours.
2. SPEED 2 will begin immediately after SPEED 1
completes. Default SPEED 2 runs at 1400 RPM for
10 hours.
3. SPEED 3 will begin immediately after SPEED 2
completes. Default SPEED 3 runs at 2200 RPM for 2
hours.
4. After SPEED 3 runtime has ended, the pump will
enter a stationary/paused state for the next 10 hours.
5. The pump will restart at 8:00am the next morning
and cycle through the default schedule again. The
pump will continue to run in this in this manner until a
custom schedule is programmed.
Note: The Start/Stop button must be pressed, and
the Start/Stop LED illuminated, for the pump to run.
