Question
I'm confused about how to wire the Toro Wireless RainSensor
Model 53770 to the Nelson SmartZone EZ. I connect the Brown
and White wires to the sensor inputs but I'm not sure where
the two red wires connect. I tried putting one red wire into
what looked like the 24v-0 opening and the other one into
the Com slot. I'm not getting a power light on the receiver.

Answer
Hey Richard, the red wires will hook to the 24 volt leads coming from the transformer. One to the one side and one to the other. What you want to look for, is the two wires coming from the transformer, and it should be marked 24 volt on the terminal strip. It sounds like you have one wire hooked to the common terminal, and you need to put it on the 24 volt outlet. Good luck and have a great day.
