Connecting Toro 53770 wireless rain sensor to Nelson SmartZone EZ. Brown/white to sensor inputs. Red wires? Tried 24V and COM—no receiver power light.
Red wires = power for receiver. Connect to 24VAC transformer output (two wires marked 24V on terminal strip). One red to each 24V lead. NOT to COM.
One red on COM = incomplete circuit. Receiver needs 24VAC across both red wires.
