Variable Speed Motor/Control
Starting the pump and motor/control
If the
run/Stop
button is illuminated, the motor is in the
RUN mode. If the Clock is set and the time of day and day
of week corresponds to a scheduled Program On time,
the motor will automatically ramp up to speed within a
few seconds. Be aware the unit will start in Prime mode
running at full speed for four minutes. After the priming
period has expired, the pump will operate at the flow
percent demanded by the operating mode which caused
the pump to start. When the unit is in Prime mode, the
word “MAX” will flash above the percentage flow indicator.
Pressing the
run custom flow
button followed by the
enter
button will start the pump in the current Custom Flow
1 setting. To start the pump in the Custom Flow # 2 setting,
press
run custom flow
twice before pressing
enter
;
Press the

running the ecotecH eZ
tm
motor/control
per the program Schedule
The
run/Stop
button must be illuminated. The
motor/control will turn on and off automatically at the
programmed start and stop times and it will operate at
the programmed flow rates. The LCD screen will display
the current operating flow rate in percentage of maximum
format, the current time of day, the current day of the
week, and the current or next Program Schedule that
will run. The Program Schedule may be overridden by
pressing the
run custom flow
button or by pressing
the
run maX flow/Vacuum
button.
The user interface includes two programmable % Flow
time periods for weekdays, Monday through Friday, and
two programmable % Flow steps for weekends, Saturday
and Sunday. These are the times at which the motor/
control will turn on and operate at the programmed
percentage flow until the time scheduled for Time Off.
the Default or preprogrammed settings are as follows:
Mon – Fri Flow 1: 7:30AM Time On and 4:00PM Time Off
running at 50% Flow
Mon – Fri Flow 2: 4:00PM Time On and 6:00PM Time Off
running at 70% Flow
Sat –Sun Flow 1: 7:30AM Time On and 4:00PM Time Off
running at 50% Flow
Sat – Sun Flow 2: 4:00PM Time On and 6:00PM Time Off
running at 70% Flow
you can also schedule the unit with overlapping
program schedules. an example:
Mon – Fri Flow 1: 7:30AM Time On and 8:00PM Time Off
running at 40% Flow
Mon – Fri Flow 2: 4:00PM Time On and 6:00PM Time Off
running at 70% Flow
Sat –Sun Flow 1: 7:30AM Time On and 8:00PM Time Off
running at 45% Flow
Sat – Sun Flow 2: 4:00PM Time On and 6:00PM Time Off
running at 75% Flow
During the weekdays, the pump will run at 40% flow from
7:30AM until 4:00PM then run at 70% flow from 4:00PM to
6:00PM. At 6:00PM, the pump will revert back to the 40%
Flow rate until 8:00PM. The same logic also applies to the
above weekend program schedule. This feature could be
used to save energy dollars by running the pump longer
hours at slower flow rates while allowing for higher flow
operation during cleaning or high traffic periods.
priming the pump
NOTICE
!
Please follow all instructions from the
pump manufacturer’s product manual regarding the pump
priming operation.
Every time the pump starts from an Off condition (0%
Flow), to ensure the pump is properly primed, the pump
will ramp to full speed (100% Flow) for four minutes.
When this occurs, the MAX icon will be flashing above
the percentage flow indicator. After the priming time has
expired, the pump will operate at the flow percent that is
shown in the display. If it is less than 100%, the MAX icon
will turn off.
