    Is it possible to make two zones run at the same time, short of connecting the solenoids together? I read the book about 3 times, and can find no evidence of it, just curious if some smart fellow out there has figured it out.

    Oh, and I seem to remember someone asking about delays between valves awhile back.... the ESP-M does this, you can delay from 0 seconds up to several hours between one valve closing and the next opening.

    1) Turn the dial to off.
    2) Press & hold the OFF key for 3 seconds until the LCD shows DELAY.
    3) Current delay between stations is shown. Default is 0 (zero).
    4) use the arrow up or down keys to change the delay (up to nine hours).
    5) Turn the dial back to auto.

    I don't remember if the person asking was inquiring about the ESP-M, but just in case...

    Nearly all solid-state controllers are one-zone-at-a-time, and only have a limited amount of power to feed to the valves. One zone valve and one master valve is the limit for some.

    Nothing for it then but to connect zones 1 & 2 in the controller. Do you think this will cause any damage to the controller or a solenoid?

    What requires you to run two zones simultaneously? You designed a system in zones, to run one zone at a time.

    I designed it to run two 3-rotor zones independently, but I can run them together at around 15 gpm, which takes 30 mins off my run time in a day. If the water pressure drops in the future due to expansion or whatever, I can go back to separate zones.

    Consider using larger nozzles in the sprinkler heads, and leave it running one zone at a time.

    I was hoping to reduce total running time so I could water it twice, trying for that deep-root ideal. As it is, it goes for 2 hours now, I dunno if that is normal, low, or high for a residence.

    On a good note, I put out some cans tonight, and got .32 average in 30 minutes.

    Larger nozzles will also reduce running time. 2 hours is fine. Beats the heck out of 18.

    Even out here on the windy plain, I have very few customers getting it done in 2 hours or less. Medium to large yards often see 4-6 hours total run time. And some large accounts have up to 20 or more zones that need that 18 wetboots mentioned. In those cases, I split the run in two days. (or even 3) If you want to only run 1 hour of a morning, once the yard is back after the install, run 1/2 the system one morning and 1/2 the next. Your controller can handle that w/ ease. Use the interval option and put 1/2 your yard on "A" and the other hald on "B". Make sure the days remaining are different from "A" to "B" and your good to go.

    On the Prog A & B option... doesn't the switch have to be in that position to run that program? For example, can I recall & run Program B if the switch is set to A? I am not sure I fully understand the A, B, C thing yet, I am only using A.

    Thanks for the reply!
