  1. Mr Irritol system is set to come on 5:30 AM and 7:00 PM. The AM does not come on and just pulses on the popups that pulse up 1/4 inch and back down and up again. If I attempt manual the same thing happens but the night time setting works perfectly. Any recommendations?

    • Hi Freddy – yep, it’d be a standard repair item – I’ll send you email with the details.

  2. Hi. Only 1 of my 4 zones is working. Plus none of the 4 zones will work if I set to manual. Thank you.

    • Hi Robert,

      That’s usually due to a valve or wiring issue. Try looking at the section about testing the transformer in the RD600 troubleshooting section. You can bypass the timer and connect the valve to the transformer directly to test it. If you have questions, let me know.

  3. Hello Dr. R! I am trying to troubleshoot a problem with a 1200. One zone does not turn on. I have tested that solenoid with connection to another zone wire and it works fine. Deduction is that its the Zone 4 live wire problem. When I put a continuity tester on #4 on the circuit board it is fainter than the other zones. are the circuit boards prone to problems like this? tx, in advance. btw, I sold my house and am trying to get out of this for as cheaply as possible!!

    • Hi Scott,
      After conversing on email, it sounds like there were two problems I’m glad it’s all working well again.


  4. Train Dial 600 R

    The initial watering valves 1&2 are working fine, however, when their watering, both #1&2 immediately repeat. What do I need to adjust.

    Thank you Don

    • That’s a scheduling conflict, usually with overlapping or too many start times. Look for that on all schedules, a, b and c.

      If all else fails, do a factory reset by following the DIY Troubleshooting page instructions.

      I can also do a phone consultation to get you going again, and am happy to help.

      Let me know what you think and we can go from there.

  5. I have a brand new RD600R. My installer said that there is an out of the box failure. There is no 24 VDC on the MV/Pump contact…which is where he is connecting a pump start relay switch wire. Are out of the box failures common on new units?

    • Hi Patrick,

      We had some emails going to figure it out. For the readers wondering about this RD600 issue, here’s the result: The timer has a feature that turns on the pmp/mv circuit when a station is on. This feature can be turned on/off per station. The feature was simply turned off. Once turned on (see the manual), everything worked normally.

      Thanks for the generous donation Patrick, I appreciate it.

  6. I have reset my RD1200 both ways still no power. The valves turn on manually. It is only @3 years old. Any suggestions?

    • Hi Terry,

      When you turn them on manually, do you mean manually at the valve itself, or using the manual function on the timer (Pressing the Manual On button after adding some minutes)?


    • I sent you a separate email with some additional questions and info; if you didn’t get it, post back here and let me know. You might want to review the DIY Troubleshooting page for the programming tips and information. Stations have nunbers and schedules have letters.


  7. My rd600-ext-r has one set of valves cooing like a dove and they continuously leak water if I turn the cap it leaks into the valve box but the cooing stops. What do I need repaired?
