Hi Carlos,


There is an electrical component (recoverable fuse) on the circuit board which limits the output current to 750mA. Please check the resistance of the valves and the pump or master valve which should be larger than 20 Ohms.

To measure the resistance of the zone valve, remove the common wire and the zone wire from the slots and set your multimeter to Ω mode.

To measure the resistance of the pump or the master valve, remove the common wire and the M wire from the slots and set your multimeter to Ω mode.


Thanks,

Hi Carlos,

Please check the wires. Are they loose or disconnected from the slots? Please also check the common wires and the master valve if you have one. If you believe the wires are correctly installed,  please check if there is a main valve/faucet that is turned off manually. To test if the controller is working properly, use a multimeter (AC voltage mode) to test the voltage between the common wire and the zone wire when the zone is active. Normally the voltage should be between 24V and 28V.

You might also want to check whether there are shorted zones or open zones. You just need to use a multimeter to measure the resistance between the common wire and each zone (remove the wires from the slots before testing the resistance). The normal reading would be 20-60 Ohms. If the reading is less than 10 Ohms then you might have a shorted circuit in the solenoid and if it is larger than 80 Ohms you might have an open circuit. Please let us know if it works.

Thanks,
