4. Secure the adapter fitting to the conduit, and
then connect the Rain Sensor to the controller
using the appropriate procedure as described in
the "Rain Sensor Wiring" section.
Rain Sensor Wiring
Select the appropriate installation procedure (Normally
Closed or Normally Open) when wiring the RSD Rain
Sensor to your controller.
!
NOTE: The vast majority of irrigation
controllers are in the normally closed
position.

Normally Closed Installation
Controllers With Rain Sensor Terminals
Many modern controllers (such as those from Rain Bird)
include built-in terminals for rain sensor lead wires.
Dedicated rain sensor terminals are usually labeled
"sensor", "SENS", "S" or "SN" on the controller's
terminal strip.
1. To connect the rain sensor, remove the jumper
wire (if present) from the controller's rain sensor
terminals.
2. Connect the red and black lead wires from the
rain sensor to the controller's sensor terminals, as
shown in Figure 7. It does not matter which wire
goes to each terminal. Do not use the blue wire.
Controllers Without Rain Sensor Terminals
Use the procedure below if your controller does NOT
have dedicated rain sensor terminals.
1. Disconnect the wire from the common terminal
("C" or "COM") on the controller's terminal strip.
Then connect this wire to the red Rain Sensor
lead wire.
2. Connect the black Rain Sensor lead wire to
the common terminal ("C" or "COM") on the
controller's terminal strip, as shown in Figure 8.
Do not use the blue wire.
Normally Open Installation
Some older controllers require rain sensors to be
installed "Normally Open" (N.O.). Use the following
procedure if your controller requires normally open
installation.
Controllers With Rain Sensor Terminals
Although rare, some older controllers included built-in
terminals for rain sensor lead wires. Dedicated rain
sensor terminals are usually labeled "sensor", "SENS",
"S" or "SN" on the controller's terminal strip.
1. To connect the rain sensor, remove the jumper
wire (if present) from the controller's rain sensor
terminals.
