Dear Simone,
24v AC power adapter 1000ma power supply is ok.
You mentioned that the valve did not open. 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.
Thanks,

ho fatto i controlli,le valvole si aprono per pochissimi secondi ( 2-3 secondi) e poi si richiudono.
Se scollego la valvola mentre è in funzione e la ricollego si riapre per pochi secondi e poi si richiude.
Ho 6 valvole hunter 24vac nuove.
Su tutte le valvole si presenta il problema, anche sulla master.
Could you please send us email to support@netrohome.com with your Netro account registered email?
We will have our technician look to this issue.
Thanks

Ho provato anche con una centralina sprite nuova e il problema persiste, ho provato anche ad utilizzare delle valvole 24vac Antelco Ezyvalve ed le valvole vengono aperte ma non vengono chiuse.
È possibile che il problema sia nell’alimentazione che uso?
