RSD Rain Sensor
The Rain Bird® RSD Series Rain Sensor is an easy to install,
durable and visually pleasing rain sensor device suitable
for 24VAC residential and commercial applications.
This high quality product saves water by automatically
measuring precipitation amounts and suspends irrigation
cycles when watering is unnecessary.
!
NOTE: The RSD Rain Sensor is a low-voltage
device compatible with all 24 volt alternating
current (VAC) control circuits and 24 VAC pump
start relay circuits. Electrical rating suitable for
use with controllers that can actuate up to ten
24 VAC, 7 VA solenoid valves per station, plus
one master valve.
DO NOT use with any 110/250 VAC devices
or circuits, such as direct-acting pump start
systems or pump start relays.
Selecting a Location
Install the Rain Sensor in a location where it can
collect natural precipitation without interference from
man-made or natural obstructions. Place the device
at a height that deters vandalism. Avoid rain sensor
mounting locations such as those shown in Figure 1.
!
DO NOT install the Rain Sensor where the
device's ability to collect and record natural
precipitation events are affected by sprinklers,
rain gutters, trees, etc.
DO NOT install the Rain Sensor where it could
accumulate debris from trees.
DO NOT install the Rain Sensor in a location
exposed to high winds.
Operation
Set Rainfall Setting
The rainfall setting on the sensor determines the amount
of rainfall needed to suspend the irrigation watering
cycle. You can adjust the rainfall setting from 1/8" to 3/4"
(3mm to 19mm). Adjustments are made by turning the
sensor dial cap clockwise or counter clockwise. To set the
rainfall setting, turn the sensor dial cap until the desired
rainfall setting lines up with the arrow on the sensor
body (A), as shown in Figure 2.
The ideal rainfall setting for your location depends on
soil type, wind, amount of direct sunlight the sensor
receives as well as frequency and amount of rainfall.
The table on the next page gives some guidelines to
help determine the appropriate rainfall setting.
