Question about Garden

1 Answer

HI i have a toro DCC control box and after coming back from holiday my sprinklers wouldnt work. I noticed on my Control box that the screen was blank so i changed the 9V battery thinking it was that. the power was still on and i still got a blank screen. when i turn the power off then the screen lights up and is run by the 9v battery, so i set all the rain days and tried to do the manual watering and nothing happened, when i turn the power back on the screen then goes blank again. i am at a loss to know what to do. any help would be good thanks.

Remove the battery. Unplug the timer. Make sure that the front of the timer is properly connected to the internal board. Plug the timer back in. Try to operate the timer using manual watering. The battery is only for backup, don't install it until you get the timer to operate on ac power first.

Toro sprinkler does not work in manual setting


The controller has an issue with manual operation. Make sure that all switch contacts are clean and working. If so, you will either have to live wth it or get a new controller.

I have a Toro 240-06-04 which is almost identical to the 250. My sprinkler system on the number one valve quit working. I thought maybe it might be a solenoid, so I replaced that and it still didn't w


Connect the wire form a working zone to the valve to zone 1. If the zone comes on you have short in the wire for zone 1. You can confirm this by connecting it to the valve that was working and it probably will not. If you have a spare wire connect it to zone 1 and in pin 1 at
the timer.

If valve still does not open and you replaced the solenoid (which is rarely the problem) the hydraulics are probably worn out in the valve. Purchase the same valve and switch out everything accept the valve body itself essentially rebuilding the valve.

Bad wire, no spare and you want to avoid running a new stretch. Merge this zone with a similar one by connecting both valves to 1 wire. If the pressure is good they should all work as 1 zone. Otherwise you will have to run a new stretch.

Toro Visiion Sprinkler Controller Troubleshooting


There are two Toro timer manuals posted:
Copy following links, for ez word search for each manual:
http://waterheatertimer.org/pdf/Toro-53794_UserGuide.pdf
http://waterheatertimer.org/Toro-53794_UserGuide.pdf
http://www.toro.com/en-us/homeowner/do-it-yourself-irrigation/timers/Pages/default.aspx

The timer can be reset to factory defaults by 'clearing program memory' following steps in manual.
Warranty period is 1 year protection against defects in workmanship, which is standard for timers from Woods to Intermatic to GE etc.

If the display is not working, and zone does not show, then that implies internal defect, or lack of power. Resetting timer might repair problem.
The timer has electro-magnetic relays, and not an internal solenoid.
The timer turns ON or turns OFF electric power to the water valves.
Water valves have solenoids that open and close when power from timer arrives at each zone.
The solenoid can make the sound you describe, but the timer relays with make small click sound as the electromagnetic relay opens and closes.

In addition to resetting timer to factory defaults, and then reprogramming you might try changing wires to different terminals.

Also the timer works on 24Volt AC transformer that plugs into outlet. It is possible to get display errors on timers when voltage is incorrect, or outlet and transformer are not connected well. Test outlet with circuit analyzer. Change outlet because outdoor outlets get corroded. Clean blades on transformer plug.

Power surge and other events can damage timers. Nearby lightning strike. Power outage causes surge when power resumes.

There is 24-hour backup battery, but the battery does not appear to be replaceable type and instead is rechargeable or capacitor type backup. So the battery is probably not the problem

Lighting disrupted the sprinkler, put in new fuse it will not work


I am sorry to hear lightning got your sprinkler. I would first start by testing to see if power is available at the controller. If you have no power then you or your electrician can work on that issue. Once you have power to the controller then if it doesn't work then lightning most likely damaged your controller and may have damaged some of the wiring and sprinkler valves. The controller board may be damaged beyond repair. I hope this helps.
