Toro GREENKEEPER 212 - Manual (Page 30)

(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 the Toro Rain
Switch into the con-
troller housing through
the access hole provid-
ed.
2. The Rain Switch cable
has four wires: two cop-
per wires and two silver
wires. Connect the
heavier 18 AWG
(1.0mm
2 ) copper wire
and the thinner 24 AWG
(0.50mm
2 ) silver wire to
the terminals labeled
SENSOR (11). Trim off
the remaining two 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.
