Control it...

Used in conjunction with the RainSwitch to indicate status, control, and reset the system after the rain event has concluded. Available in both Manual and Automatic Reset versions to meet various agency requirements. 

Pilot Station with Auto-Reset - #JICATIPB2L-C
NOTE: (not accepted by L.A. County Sanitation)

Normal Mode (No Rain):
The pump or valve is in its normal mode, with flow into the sewer system. The green light is on, displaying “normal condition”. The automatic timer actuates and opens the solenoid valve (draining the RainSwitch) for 15 minutes, every 10 hours. When in the normal mode, this function has no effect on the system.

Divert Mode (Raining):
Once a 1/10th of an inch of rain has fallen, the RainSwitch will change the state of the pump or valve, diverting the rainwater to the storm drain system.The green light goes off, the red light will go on, once the valve has reached it's divert position, indicating the system is in the “divert mode”. Again, the automatic timer will reset the RainSwitch every 10 hours, causing the pump or valve to return to its normal mode. This will return the flow to the sewer system until a 1/10th of an inch of rain is again detected. This sequence repeats itself until it stops raining, and the system returns to the “normal mode” referenced above.

Pilot Station with Manual Reset - #JIC1PB2L-C
It functions the same as above except after it stops raining, an operator will depress the reset pushbutton on the station, causing the solenoid valve to open (draining the RainSwitch). The pushbutton must be depressed until all water is completely drained from the RainSwitch. This will return the system to the “normal mode” position.
