Rain bird s line of pump start relays offer the protection and reliability that your irrigation system needs when using a pump to pull water from an external water source like a pond creek or low pressure potable water source.
Irrigation pump relay wiring.
Rain bird psr universal pump start relays provide pilot duty operation for all types of electrically driven pump equipment with available coil voltages of 24 110 and 220 vac.

Since the generation 1 controller outputs 24vac a pump start relay is required when using a pump with the generation 1.
In addition to this recommendation hunter also recommends all controllers be mounted 15 4 5 m away from pumps and high voltage devices.
A pump start relay serves as a switch that activates 110 220vac power to the pump when the generation 1 smart sprinkler controller s master valve is enabled.
Wiring 24 vac use a minimum distance of 15 4 5 m between the controller and the relay to dampen electromagnetic noise.
