The relay can be located up to 800’ away from the timer using 18 AWG wire. The two red wires are labeled L1 IN and L2 IN. These wires will connect to the wires coming from the power source (120 or 240 VAC). Power wires from the power source and to the pump should be 12 AWG with a temperature rating of 55⁰.

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.

2021年4月26日 · Connect a common wire to the C (Common) terminal inside the controller and connect the remaining wire from the pump start relay to the P (Pump) terminal. The two transformer wires go to the 24vac location.

2025年1月27日 · A pump start relay serves as a switch that activates 110-220VAC power to the pump when the Rachio controller’s master valve is enabled. Since the Rachio controller outputs 24VAC, a pump start relay is required when using a pump with the Rachio controller.

Learn how to wire a pump start relay to control a pump system for efficient water distribution and irrigation. Get step-by-step instructions and diagrams.

A pump start relay is a device that uses a signal from the controller to actuate a separate electrical circuit to energize a pump to provide water to your system.

Rain Bird Universal Pump Start Relay - 110 volt Use copper wire rated at 75 Deg. Celcius only - - - Disconnect supplied by others. NOTE: all motors must be thermally protected. Circuit protection must be provided by installer. Grounding per N.E.C.- Ground lug torque: 45 in/lb. Terminal block torque specs: 9m/lb.

2024年6月24日 · Run the AC wires of AWG 12 with a temperature rating of 155º F/68º C into the relay box and connect them to the appropriate relay wires. The wires are labeled “power in” from main power source, and “power out” to pump (refer to diagram on housing unit).

• Never work with electrical wiring on a live circuit. Refer to wiring diagram on motor plate for proper voltage and wire placement. Refer to NEC wire cable chart for proper size wire. Undersized wire can affect pump performance. Locate the Master Valve (mv) and Common (com) inside Lawn Controller.

2023年9月6日 · Knowing how to read and comprehend an Orbit pump start relay wiring diagram is essential for any do-it-yourselfer tackling an irrigation pump installation. An Orbit pump start relay is a device used to control the start and stop of an irrigation pump.
