Connecting a Toro Rain Switch
(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
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.
