Can you run two sprinkler zones at the same time?
Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
What voltage are irrigation solenoids?
24 volts
Electric solenoid valves are powered by 24 volts AC (VAC) from the irrigation controller. Whenever the controller turns a valve on, it sends 24 VAC to the solenoid.
Are all sprinkler valves 24 volt?
Sprinkler valves are operated electronically using low voltage 24v power generally of 18 gauge wire for residential, and 14 gauge wire for commercial. Valves require one 24v power wire for each valve and a commonly connected “common” wire shared between each valve.
What causes two sprinkler zones to come on at the same time?
Water is coming out of multiple zones at the same time: For the valves to stay open in one zone, while shutting outlets in other zones, there needs to be a minimum amount of water pushed through the valve. For instance, our 4,000 series require 10 gallons per minute (GPM) to operate and our 6,000 series require 15 GPM.
What color is the common wire on a sprinkler system?
white
The common wire is usually white in color and runs from your controller to your master cylinder and then to each of the other valves on your irrigation system in turn. If something happens to cut your common wire, then every valve after the cut will fail to turn on when activated.
How does an irrigation system use the same wire?
They operate irrigation valve solenoids by receiving both signal and power from the same wire path. This allows the installation of many irrigation stations (or valves) down the same wire run, rather than requiring a separate power wire for each solenoid.
What makes a 2 wire decoder irrigation system?
Chances are, you’ve already installed or inherited a 2-Wire decoder irrigation system, or at least heard about them. This game-changing valve control technology is here to stay, and for good reason. Here’s a little of the what, why, and how, that makes 2-Wire decoders a powerful option.
How big of a wire do you need for a solenoid?
While specifications vary, path runs of up to 15,000 feet (4500 m) are possible with 12 AWG (3.3 mm2) wiring in large control systems. Smaller systems may use 14 AWG (2 mm2), or even 16 AWG, for distances that would require much heavier wire in conventional solenoid wiring.
How are decoder systems different from conventional wiring?
Decoder systems differ from “conventional” wiring because they allow control of many valves over very long distances, with a corresponding savings in wire and labor. However, the installer must invest in the decoder electronics themselves which will be offset by some of the wire savings.
