Pump Start Relay Wiring
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.
Install in the “M” terminal slot, and enable the Master Valve from
the device settings under Advanced within the Rachio App.
Make sure that the total draw of the Pump Start Relay plus the
draw of the valve does not exceed 1.3 amps at 24 VAC, 60 Hz. The
controller does not provide main power for a pump.
