TROUBLESHOOTING
Symptom Possible cause
Station does not come on
• Make sure a 9V lautching solenoid is used
• Check electric wiring
• No run time has been set for the station
• Sensor system is preventing irrigation
• Start time has not been entered for the
program to which the station is assigned
Water budget for the station’s program is
set to 0%
I remove batteries from the controller but the
irrigation continues
• Battery powered controllers operate by
impulses. To stop watering, the electric
valve needs to receive a shutdown
impulse.
Removing batteries prevent the controller
from sending the shutdown impulse.
