I was wondering if anyone is aware of a timer for sprinklers that doesn't
stack the start times of the different zones. I need a timer for at least 4
zones and I need all of them to be on at the same time for part of the day.
Does anyone know of such a product?

Thanks,
Harry

I don't know of a specific timer that will do what you want, but you could
use x-10 relay modules and control them from your computer to turn on/off up
to 256 times a day in any combination you want. I have controlled some
irrigation vales this way for hanging baskets and containers that I want to
mist several times a day for a minute or two.

You could just wire the four valves to one "zone", or to a relay controlled
by the timer, and a larger 24VAC transformer controlled by that, if needed.
But, do you have enough water supply to handle 4 zones on at a time?

The problem is not that I need all four zones to be on all at the exact same
time. I need all four zones to be on at different times, but all of these
four different times overlap each other at some points in the day. Hope
that makes more sense.

Several commercial timers will do what you want for a lot of money. My
Calsense system also tracks flow, has alerts for over/under flows,
uses ET data and costs several thousand dollars.

Rainbird controllers can overlap programs ESP-8MC will do this. Other
controllers has the ability to run D-drip program simultaneously with
program A, B or C to maximize hydraulic capacity and minimize watering
time.

$467 USD for an 8 station.

There's another way to assure a constant start time for each zone, get an
8-zone controller and only use zone 1-3-5 & 7. If zone 1 is 20 mins and starts
at 9am, and you want your next zone to start at 10am, then set unused zone 2
for 40 mins.

It is the rare water supply that will supply enough water for more than one
large zone at a time.

with drip zones it's common practice.

I am connected with a company that offers a product that will allow up to 4
of the 8 zones to overlapped as you describe.

It is modified version of our standard Rain8 X10 irrigation controller and
has the same features as described on the Rain8 website, with the above
exception. The intended application is drip irrigation and greenhouse
misting.

If X10 operation is not wanted, we also offer a PC driven (RS232) 8 zone
irrigation controller.

For more information please email me a .

I hope this did not come accross as an advertisement and that it was useful
to someone.
