MINUTE WATERING
1) Twist the control head counter clockwise until it
hits the stop (a small amount), then separate the
control head from the black support housing. The
unit will separate showing the switches and
terminal strip on the left.
2) Using a fingernail, a pen tip or a small
screwdriver select the switches on the red switch
panel to the watering time you wish – 8 minutes,
20 minutes or one minute. As shown in the
pictures and captions: Switch 1 ON and Switch 2
ON is 3 minutes;Switch 1 ON and Switch 2 OFF is
8 minutes; Switch 2 ON and Switch 1 OFF
provides 20 minutes of watering; both switches
OFF provides one minute of watering. Note: this
is only the watering time that occurs when the
SET point (by the knob) is greater than the
READING. The reading is shown by the blinking
LED that repeats the last measured soil moisture
every 20 seconds.
Normally 3 minutes works well. 20 minutes is
used when a deep watering is desired, or with the
48 plant extender kit with the ½ gallon per hour
drippers or similar. The one minute setting usually
used when the three minutes it too much water,
such as watering small potted plants.
