Been using a Toro Rain Sensor TWRS connected to my Toro Vision II controller for few years now.
We had to turn off the breaker panel today to install a new breaker for my solar arrays and when we turned it back on the power to the sensor seems gone. (At least I think this was the process as I recall the lights on the sensor ON before we turned the breaker OFF --- I did notice the sensor was OFF until later in day hours after the breaker had been turned back ON.) No lights on sensor... I checked wiring to controller... nothing changed....... The controller is fine however.
I notice the controller has 2 fuses but figure it may be for the controller.
Not sure why the sensor lost power...
Thoughts?

More info: I disconnected the TWRS from the controller. The controller has LED lights but does not allow water to flow.
I can see each LED light up for each zone as programmed but the water is not flowing. Something happen to the controller but its odd since it has power and the program runs. I did connect the COM wire back up correctly (this was connected to the TWRS). Water is ON and fuses are OK.
I notice the controller is plugged into an electrical outlet that is direct wired to the breaker panel. Not sure I know which breaker controls it (if any) but it does light up so I assume it has power.
I am confused...

So nobody loses sleep.... seems the electrician loosened a wire from the controller to the transformer when installing a line t the breaker box..
Once re-attached all worked fine.
