Before attempting to install the RainSensor, please
read through these instructions in their entirety.
Since the RainSensor is designed to work  with
most makes and models of controllers, you  should
also refer to the instructions provided with  your
irrigation system controller for specific information
regarding the connection and use of a  rain sensor
or rain switch.
Changing the RainSensor Configuration
To Controller
The RainSensor is designed to work
with Normally Closed or Normally
Open sensor circuits. If connecting
the RainSensor to the controller’s
sensor terminals, first verify which
type of sensor circuit is required by
referring to the controller user guide.
The RainSensor is set for Normally
Closed sensor operation. If Normally

The RainSensor can also be mounted on  any suitable solid struc-
ture such as the side of the  roof, a shed or fence using the two sup-
plied stainless steel screws. See Figure 5   below.
Important: Please note the following information regarding
installation and use of the RainSensor.
The RainSensor is designed to operate with  24 V ac power
only. Connecting the RainSensor control wiring to  120/240 V ac
power may result in severe equipment damage.
Installation methods must comply with all applicable  national
and local building codes. If you are  unsure about proper wiring
practices, have a qualified contractor perform the  installation
for you.

Routing the RainSensor Control Wire
Select a mounting site for the RainSensor  as close to the controller
as possible. If the 25' RainSensor control  wire will not reach the
controller, it can be extended up to  100' using 18 AWG outdoor-
rated wire. The installation site must provide  unobstructed rainfall
and sunlight conditions similar to those of  the landscape being
watered. Make sure the RainSensor will not  be in contact with spray
from the sprinklers or runoff from the  roof.
Route the RainSensor control wire back to  the controller. Avoid run-
ning the wire over sharp edges where  cutting or abrasion of the
wire insulation may occur. For best results,  hide the wire where
possible by it tucking it under shingles  and/or moldings. Seal any
holes made by passing the wire through  structure walls.
