After the Water Level Sensor has adhered, use the magnet to
calibrate the water level. To do so, place the magnet in the bottom-
right corner of the Level Sensor, and hold it there for two-seconds
before removing it. A green light will appear on the sensor and
flash three times. This indicates the calibration has begun. A green
SENSOR light will also flash on the Valve Controller for about one-
minute, as the water level is set.
This step will conclude with a solid green SENSOR light. The
LevelSmart may start to fill for 7-minutes after installation. If
additional water isn’t required, shut off the water supply or
turndown the flow control knob for this 7-minute period. In some
cases, the LevelSmart does not fill immediately after pairing. As
long as the green SENSOR LED is visible, the unit has paired
successfully.
If LevelSmart is being installed to a smaller body of water, such
as a spa or small swimming pool, make sure to reduce the flow
control knob (the middle knob) so that the amount of water is
reduced on each fill. To do so, it’s recommended that the flow
control knob is tightened down half-way.

Understand how LevelSmart works:
After
installing and pairing, the LevelSmart sensor
will wake up every 30-minutes, take the
current water level measurement, and
communicate that information to the Valve
Controller. If water is needed, the controller
will open up the valve and fill for 7-minutes.
LevelSmart will continue to check the water
level every 30-minutes.
