Note 1: Checking the Time Delay – Turn the
time delay down to 5 seconds. Next, cross the
red and blue wire. The “on” light should turn
on. After 5 seconds the system should shut off
and both the “on” and “up” lights should be on.
Note 2: Filling system lines may require
multiple run cycles to build enough pressure to
initiate the sensor.
Did Did You Know?
During a normal run cycle, no
lights should be lit on the time delay.
Should a sensor detect a possible system
problem, the “on” light will engage. If the
system is shut down during a cycle both
the “on” and “up” lights will be lit for the
duration of the lawn controller cycle.
