(Optional)
The Toro Rain Switch is a remote rain sensor which can
be connected directly to your GreenKeeper 212 to auto-
matically interrupt watering during rain.
A sensor bypass switch is provided which enables the
Rain Switch operation to be turned On and Off.
When the Rain Switch absorbs rain water it automatically
signals the GreenKeeper 212 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 disappear and controller operation will
resume as programmed.
1. Route the wire cable from Toro Rain Switch into the
controller 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
2
) copper
wire and the thin 24 AWG (0.50mm
2
) silver wire to the
terminals labeled SENSOR (11). Trim off the remain-
ing two cable wires.
3. Set Sensor Switch (10) as required: ON allows the
Rain Switch to interrupt watering; OFF bypasses the
Rain Switch input.
Note: The Toro Rain switch is a normally closed
device. To install a normally open Rain Switch,
refer to the instructions provided with the device and
and install accordingly.
