Dear customer,

The primary reason your controller is not functioning is likely due to a wiring issue, rather than incorrect parameter settings. Please check the water valves to ensure the irrigation system is operating correctly.

To investigate further, you can use a multimeter to measure the resistance between the common wire and each zone. Make sure to remove the cables from their slots before testing. A normal reading should be between 20 and 60 ohms. If the reading is less than 10 ohms, there may be a short circuit in the solenoid valve. On the other hand, if the reading exceeds 80 ohms, there could be an open circuit.
