Check to make sure there are no exposed or loose connections.Assemble conduit piping and connect wiring from the pump motor to the other side of the relay (LOAD OUT).Assemble conduit piping and connect AC power from the power source to one side (LINE IN) of the relay.

To prevent electric shock, turn the main circuit-breaker switch to “off” prior to making electrical connections.Improper installation could result in shock or fire hazard. Wiring to Power SourceĬonnecting the pump start relay should only be done by a licensed electrician following local codes. We usually recommend wiring to the last zone that is not being used in the controller. NOTE: With an HC Hydrawise controller, any one of your 6 or 12 zones can be configured to act as the pump start relay. MAXIMUM one-way wire length (do not go this far!) Attach the opposite control wire to the M/V terminal. Secure the valve common wire to the “ COM” (Common) terminal. Strip ½' (13 mm) of insulation from the ends of all wires.Route wire through the conduit or one of the openings on the bottom of the cabinet.

Install pump start relay cover plate and four screws.Use wire nuts to make the connections and verify they are secure.Run a single wire from the 'P/MV' terminal on the controller to the other yellow wire on the pump start relay.Run a single wire from the 'common' terminal on the controller to one of the yellow wires on the pump start relay.Detach the pump start relay cover plate by removing the four screws with a Phillips screwdriver.In addition to this recommendation, Hunter also recommends all controllers be mounted 15' (4.5 m) away from pumps and high-voltage devices.

Use a minimum distance of 15' (4.5 m) between the controller and the relay to dampen electromagnetic noise. Whenever one of the irrigation zone valves is told to open by the controller, the controller also signals the pump start relay to turn the pump on. Typically, one zone valve is turned on at a time and controls the irrigation in a specific area of your landscape. Hydrawise controllers support 6- to 54-zone valves, depending on the model. Zone valves are the individual valves that operate a group of sprinklers or drip emitters. When a system requires the use of a booster pump or pulls water directly from a creek or pond, it’s imperative to include a relay to activate the pump each and every time. A pump start relay is a relay box that activates a pump every time a zone is activated from the controller. In this article, we will discuss the following topics:
