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 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...
