Double Switch:Operate 2 Valves from a Single StationIrrigation Problem SolversModel RCOWorks on most 24-volt systems, rated for 50,000 operations and 0.5 AMPSDoes activating 2 valves with only one pair of good field wires sound impossible? Not with Double Switch.Now you can solve broken wire headaches without needing to trench in more wiring.Just like other popular doubling devices, the Double Switch will alternately activate each of the zones with every other cycle of the controller.• Uses one wire to power 2 different zone valves by alternately operating them with every other cycle of the controller. The first time it receives power, it operates the first zone valve for the programmed time. The next time the station is turned on, it switches to the second valve and runs it for the programmed time. The every-other cycle operation is simple.• Both valves run for the same amount of time.• Bypass a broken wire by running two valves from one wire. No need to trench additional wire. • Divide low pressure zones by adding a new valve.Note: if independent timing and individual control is needed for the two valves, use the R Co. Add-A-ZoneThe unit is typically directly buried near the two valves it controls.On the left side of the unit, connect the red wire to the zone wire coming from the controller. Connect the white wire to the common coming from the controller.On the right side of the unit, connect one yellow wire to the first valve, and the second yellow to the second valve. Connect the white common wire to both valves.The two station outputs will be sent through the single zone wire.Standard features:Solve these problems:Installation Instructions:Providing Quality R Co.
