SETUP: (continued)
3. Position the Primary Sensor Tube in the water at the point on the
tube where you want to set the “lower limit”. This will be the level
where the pump will turn OFF. We recommend that you set this so
that it is at least one inch from the open end of the tube.
4. Press the DOWN button to set the lower limit.
5. The three upper lights (6, 8 and 10) will now blink in an upward
sequence.
6. Position the Primary Sensor Tube in the water at the point on the
tube where you want to set the upper limit. This will be the water
level where the pump will turn ON. We recommend that you set
this between 0.2 to 4 inches above the lower limit point.
7. Press the UP button to set the upper limit.
8. All six lights will turn on briefly to indicate success. These settings
are remembered even after power is removed from the unit.
DUTY CYCLE SETUP
1. Power down the ATO unit.
2. Press and hold the UP button
3. Power up the ATO unit
4. All six lights will flash twice to indicate that you are in Duty Cycle
Mode, then one or two lights will blink rapidly, indicating the
current setting for Duty Cycle Mode. (See Page 7 for explanation.)
5. Press the UP and DOWN buttons to adjust this setting.
6. To quit this setup mode, simply remove power from the ATO. This
setting will be remembered.
SETTING PUMP SPEED
During normal operation, the lights will indicate the SPEED at which the
pump is operating and the state of the pump — on or off. Solidly lit lights
indicate that the pump is running; blinking lights indicate that the pump is
not running. In both instances, the lights indicate the SPEED setting of the
pump. Whenever the pump is running, you may use the UP and DOWN
buttons to adjust the pump SPEED. (See Page 10 for further details.)
