BYPASSING THE SENSOR
Should you desire to bypass the operation of the rain sensor for any reason (i.e.,turn on your system even
though the rain sensor has shut "off" due to rainfall), there is an easy way to do this. Simply go to the rain sensor
and raise the rain quantity "cap" setting higher, or completely remove it altogether. This takes the pressure off
the switch button, which allows the valve circuit to close again.
Note: Using the Manual switch on the controller may not bypass the sensor.
MAINTENANCE
There is no required maintenance for the unit. The rain sensor does not have to be removed or covered
for winterizing purposes.
TROUBLESHOOTING
Follow these simple checks before replacing your rain sensor:
System will not come on at all:
A. Check to see that the rain sensor discs are dry and switch "clicks" on and off freely by pressing the top of
the spindle.
B. Look for breaks in the wire leading to the rain sensor and check all wire junctions.
C. If the rain sensor is dry and the wire leading to it is good, check the rain sensor switch by nicking the
insulation of the two "outer" wires near the unit to expose copper. Turn one sprinkler zone on, and apply
a "jumper wire" across the two exposed wires. If the sprinkler now comes on, the switch is bad. Wrap all
nicked wires with electrical tape.
D. The rain sensor is wired to function with most controllers (normally closed). If you are unable to make the
sensor work with the suggestion above you may have a unique controller (normally open).
System will not shut off even after heavy rainfall:
A. Check wiring for correct installation (See "Adjustments and Operation" section).
B. Check sensitivity setting on rain sensor, and move the cap to a more sensitive setting. The rain sensor is
an accurate rain gauge and can be verified by setting up a "tube" type rain gauge in the same vicinity and
making periodic readings.
C. Check for obstructions to rainfall such as overhangs, trees or walls.

INTRODUCTION
Thank you for selecting a K-Rain R-200 RainSensor. This sensor will provide conservation, convenience, and
flexibility to your fully automatic watering system. Never again will you see your sprinklers running on a rainy
day. Now, after a set amount of rain has fallen, the sensor engages a switch that will prevent the controller from
watering. Once the rain sensor has dried sufficiently, the sensor allows normal sprinkler operation.
