Thank you. I've been told that Weathermatic originally made the valves for RainBird and Hunter (and perhaps still does), and later began selling them directly under the Weathermatic name. Any truth to that?
I'm getting bids for a new sprinkler system installation and would appreciate comments on quality and reliability of Weathermatic vs. Hunter vs. Rain Bird components.
Thank you. So that means, I assume, that it takes separate time-keeping circuitry (chips, etc.) powered by either line voltage or battery, to maintain clock and date settings during power failures. Why is this absent in so many controllers when it’s so essential to proper automatic program operation? Is it merely a cost-saving factor?
Good idea, scercpio, but I'm afraid I wouldn't begin to have the smarts to make it work. Besides, my present internet provider isn't reliable enough to depend on for consistent service. Incidentally, do you (or anyone else reading this) happen to know why controllers that have a non-volatile memory for program settings, don't have it for the clock and date too? Is there some kind of digital problem that way?
Thank you for your information. Looks like a good choice.
Thanks for the recommendation of the Hunter XC 600 controller. I see, though, that the XC models are discontinued, and replaced by the X-core models. Do you know if these still have the battery backup as you've described? http://www.hunterindustries.com/irrigation-product/discontinued-models/xc
Another item: On the box for the SST it says, "No need to reprogram after a power outage. All timer settings are stored in memory indefinitely. No backup battery needed." But I find that if there is a power outage for more than a very few minutes the clock setting is lost. And that effectively stops everything else no matter what. If I'm out of town and the power goes out for even a very brief time, my lawn will not be watered because of this. Am I missing something? Do you know of any controlle...
Quoted from "mrfixit" Try setting all the zones to 8 am then they'll run in sequence. Why would zone 2 come on at 9 am when you've told it to come on at 10 am? Well, start times have to be specified for each zone separately, and I thought maybe on "Auto Run" it would over-ride the set times so all zones run sequentially. Thus I wouldn't have to set each zone separately if I wanted to change the cycle to start at a different time (Zone 1 setting). I need to do this periodically, and my old contr...
I’ve just bought a Rain Bird SST-600i controller and am trying to put it through its paces. When it’s on “Auto Run” and Zone 1 has been completed, evidently it won’t automatically go to Zone 2 until the starting time for that Zone that I’ve set up. In other words, if Zone 1 starts at 8:00 am and runs 60 minutes, and Zone 2 is set to start at 10:00 am, it won’t go to Zone 2 right after finishing Zone 1, but not until 10:00 am. That means I have to set each zone to start at the specific time the p...
Perhaps I'm not "getting it," but do you mean to connect the wires from three controller zones all to one zone valve? How would that work to alleviate my problem?
Wet_Boots: Thank you for your kind consideration of my problem. I'm embarrassed to now report that the aforementioned pilot light isn't related to the problem after all, as the electrical pulses to the master valve have now returned in its absence - - and they're still resulting in the serious water-hammering I described, a few hours after completion of the regular watering cycle. So that would seem to bring the cause back to the RC-7A itself, as I cannot think of any other culprit. I do apologi...
Quoted from "Wet_Boots" You should take the lamp and install it at the master valve, in parallel with the solenoid, That's exactly the way I had it when the trouble occurred. (The lamp is the size of a flashlight bulb, with bayonet base.)
Quoted from "Wet_Boots" Sounds very much like Operator Error to me - how many zones are in the system? OK, I'll bite - - what kind of error might it be? I've checked it out as much as I can, and I know it sounds absolutely ridiculous. There are seven zones on the controller, but only five are in use.
I have a Rain Bird RC-7A controller. Recently I connected a pilot light (24 volt bulb) to the terminals for the master valve (Asco solenoid valve 8210G009). A few hours after the regular watering cycle is completed, the controller sends one or more electrical pulses to the master valve. This causes the valve to suddenly open and close, which results in a horrendous water hammering in the supply pipe coming from the basement to the vacuum breaker system. Disconnecting the pilot light stops the pr...
