    • Hi Alex, try following the reset instructions on my DIY page, that should get it done. If not, let me know.

  1. I checked input voltage which is running ~27 volts to my rd600 terminal board, but when I check each of the output terminals the voltage is jumping between 0 and 27 volts. Is this something you can repair? (edited)

    • Hi John,

      Yes, we repair that problem frequently. We’re not busy now so we’re turning them around in a day, sometimes less. Send it in and we’ll take care of it for you.

  2. My Irritrol Rain Bird control panel keeps flashing FU5 with the number 9 above it. It doesn’t appear that zone 9 is working. What does FU5 mean and what should I do.
    Thank you

    • Hi Bill, — look at my DIY Trouble shooting page for the entry about the FUS message. I have a lot of information there to help you.

  3. i just changed the current time back to one hour earlier for daylight savings time, The time Blinks and I don’t know if this is the way it should be. I seem to have figured out with much difficulty how to select the stations, does — means ON and OFF means off?. I have kept Set Programs in the middle yet the time was not blinking before I moved it back one hour. You system is complex and I have had to hire somebody to deal with helping me and paid a total of 160.00 for two home visits.

    • Hi Carol,

      You should know that I’m not the company who made the timer, I’m just someone who likes helping people with them and getting a little for the repairs I do. Please don’t hire anyone to come out, instead, make an appointment with me and we can go over it together on the phone. This way, you’ll learn how to do it so you don’t need to hire anyone any more.

      With that in mind, I’ve put together some tutorial and overview information on my website to help people understand how they work. Believe it or not, the rainDial timers are actually the easier ones to understand, all you need is a few key bits of information and it’ll make more sense.

      The blinking time could simply mean that there was a power outage, or that it needs repairing. They tend to behave intermittently as they fail.

      Although I’d need a little more info about the current switches and settings to answer your question, I believe you probably have the timer in Skip-Days mode. This means it runs every N-number of days depending on what you set N to. If you’re in skip-days mode, it doesn’t make sense to have an on-off setting for a day of the week. I.e., if you skip every 10 days starting today, you don’t really need to set Tomorrow (say Sunday) to be on or off, it just runs every 10 days regardless of what day of the week it is.

      To put it simply, You’re trying to set the day of the week to be on or off when you’re in skip day mode. It will behave the way you would expect if (an ‘on’ and ‘off’ option without –), if you are not using the skip-days feature. If the LCD screen shows SkipDays in the corner, then you’re in that mode.

      You’re probably wondering “how do I turn off the skip days feature that is confusing to me?” Simply put the dial on skip-days, the bottom switch in ‘set-programs’ and press the +- buttons until it goes down to 0, or off. Now you can set the dial to a day of the week and you’ll see ON and OFF as you’re expecting.

      Let me know if that helps,
      Regards,
      Brian

      p.s., I agree, sprinkler timers can be a bit complicated sometimes 🙂 I’m also way cheaper than that other guy and you’ll learn how to do it yourself.

  4. i have a RD900 when i try to manually switch to a zone, zone one comes on if im on zone 2,3,all the way to 9. i have to keep trying sometimes it take many tries to get it to go one for the zone selected. any ideas ?

    • Hi Tom,

      I have a few thoughts, but need a little more info: Do you have a water pressure pump as part of your system, or just the basic valves? Also, when 1 comes on when you don’t expect it to, do you see ‘1’ in the upper row of the display?

      I can guide you further if you provide a little more info. You can also reach me at rainDialDoctor@gmail.com.

      thx,

  5. As a follow up to my question about rain dial displaying “OPEN” on all stations when trying to manually start the station. ..

    It is a blue rain dial plus 6 station. Date code 072898. I coudln’t find the model number. I am not the original home owner.

    Can this be fixed?

    • Hi,

      OPEN usually indicates that the wiring is not connected somewhere. The timer tries to turn things on and then detects current flowing. If it doesn’t see any, it declares it ‘open’.

      Check the wiring at the timer box as well as the valve box(es). If you don’t find anything, let me know. If it’s a total control, it may be something I can repair, you’d just have to mail the dial portion as well as the back terminal board, but not the case or transformer.

      Regards,
      Brian

  6. When I manually try and run a sprinkler all it does is display “Open” and nothing happens. It does this for all 6 of my values. Always worked until recently. Any ideas? Thanks

  7. I wanted to run my values manually so I selected the value put in the time and hit run. “OPEN” appears and the sprinkler does not turn on. This has worked for 20 years so not sure what the problem is. Tried it with every value and the “OPEN” message appears for all and none turn on
