SETTINGS
When the ATO is initially plugged in and powered up, the bottom light
(0) will blink rapidly for three seconds before engaging the pump. At this
time, the pump may be set for FILL or DRAIN mode.
NOTE: Setting the high and low levels may be performed at a table using
a large glass of water. We recommend using a waterproof marker
to indicate your set points on the Primary Sensor Tube. This will
assist you when installing the Sensor Tube Assembly in your SUMP.
FILL MODE SETUP
1. Power up the ATO unit
2. Within 3 seconds, while light 0 is blinking, press the UP button for
two seconds, then release it. The three lower lights (4,2 and 0) will
blink in a downward sequence.
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 on. 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 OFF. 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.
DRAIN MODE SETUP
1. Power up the ATO unit
2. Within 3 seconds, while light 0 is blinking, press the DOWN button
for two seconds, then release it. The three lower lights (4,2 and 0)
will blink in a downward sequence.
