(Optional)

The Toro Rain Switch (model # 53221) is a remote rain

sensing device which can be connected directly to your

ECx to automatically interrupt watering during rain.

A sensor bypass switch is provided in the ECx which

enables the Rain Switch operation to be turned On and

Off.

When the Rain Switch absorbs rain water it automatically

signals the ECx to suspend all watering operations. The

“No Watering” symbol will appear in the upper right

corner of the display until the Rain Switch drys out and

automatically resets. The “No Watering” symbol will dis-

appear and timer operation will resume as programmed.

1. Route the wire cable from Toro Rain Switch into the

timer housing with the valve wires.

2. The Rain Switch cable has four wires: two copper

wires and two silver wires. Only two of the wires are

used. Connect the heavier 18 AWG (0.75mm

) copper

wire and the thin 24 AWG (0.50mm

) silver wire to the

terminals labeled SENSOR (8). Trim off the remaining

two cable wires.

3. Set Sensor Switch (6) as required: ON allows the

Rain Switch to interrupt watering; OFF bypasses the

Rain Switch input.
