Introduction
Welcome to Rain Bird
Thank you for Purchasing the Rain Bird Simple To
Program Controller! In the following pages, you
will nd step by step instructions on how to use
every function included in your STP Plus Controller.
Thanks again and we hope you enjoy your new
Controller.
Controller Features
Rain Bird’s Simple-to-Program (STP) controllers
are indoor controllers that have 4, 6 or 9 zone
capability. Custom irrigation schedules are entered
for each zone to match specic irrigation needs.
Simple to use “At-a-Glance” programming displays
all of the irrigation schedule information for each
specic zone at the same time on the controller.
Key features of the STP Plus Controller:
Independent zone control gives the
exibility to create individual, specic
watering schedules for each zone.
The STP Plus controller provides multiple
start times per day (with user selectable
osets) on an individual zone basis.
The Adjust Water feature allows the increase
or decrease of irrigation run times for all
zones quickly.
In the event of a prolonged rain, the irrigation
schedule can be delayed up to 72 hours
using the controller’s Rain Delay feature.
The Water All and Water Zone buttons
manually water all zones or a specic zone
without impacting any zone’s previously
set schedule.
To help manage water restrictions, the
controller can be set up to only water on
specic days of the week or “odd or even” days.
The irrigation schedule is saved in the
controller’s non-volatile memory in case
there is a power outage. Date and time are
stored with an internal lithium battery for
up to seven days.
Extra 24 volt terminals are available on
the terminal strip to allow attachment of a
Wireless Rain Sensor (not included) or other
powered accessories.

NOTE: The STP Plus Controller is designed
to prevent any two zones from watering
at the same time. This feature is called
“Program Stacking”. If more than one zone
is scheduled to irrigate at the same time,
the next zone will begin irrigating when the
previous zone has nished.

Install Master Valve or Pump Start Relay
This example shows a typical Master Valve connection. A Pump Start Relay connects to the
controller the same way, but connects differently at the water source.
STP Plus Controllers allow a Master Valve
or Pump Start Relay to operate whenever
a valve is operating (pumps are used in
some places to draw water from a well
or other source). If you are activating a
pump from the controller, you must install
a Pump Control Relay.
NOTE: The controller does NOT
provide main power for a pump.
Connect the color-coded “hot” wire
A
from the Master Valve (or Pump Start
Relay) to the controller terminal
marked MSTR VALVE.
Connect the common wire (usually
B
white) from the Master Valve (or
Pump Start Relay) to one of the
COMMON terminals.

Additional instructions for connecting a Pump Start Relay.
To avoid possible pump damage
C
when using a Pump Start Relay,
connect a short jumper wire from
any unused zone terminal(s) to the
nearest zone terminal in use.
For example: if a 4 zone controller
model is in use with only two zones
conected, route the terminals for
Zones 3 and 4 to the nearest active
terminal (in this example, Zone 2).
NOTE: Make sure that the total draw
of the Master Valve or Pump Start
Relay, plus the draw of the valves
does not exceed 0.650 Amps at
24VAC, 60 Hz.

Wires not properly connected. Verify all field wires and master valve/pump start relay wiring is
Wires loose or cut; corroded
connections.
Dial not set to AUTO position. Verify the dial is in the AUTO position.
If a Rain Sensor is installed, it
may be activated.
If no Rain Sensor is installed, the

yellow Rain Sensor terminals
may be damaged or missing.
An electrical surge may have
damaged the Controller’s

Verify the main water line and all supply lines are open and
operating properly.
connected properly.
Check field wiring for broken, cut, or “skinned” wires and
replace if necessary. Check all wire connections and replace
with watertight splice connectors as needed.
Wait until the Rain Sensor dries out, or disconnect the Rain
Sensor from the yellow terminals on the Controller and replace
it with a jumper wire connecting the two yellow terminals.
Connect the two yellow Rain Sensor terminals in the
controller’s terminal bay with a short length of 14 to 18 gauge
jumper wire.
Press the Reset button located under the wiring bay cover. If
there is no permanent damage, the controller should resume
normal operation. Current time and date will need to be
entered, but the watering schedule should remain intact.

An electrical surge may
have damaged the
Controller’s electronics.
Verify the two-prong connector is connected and the
transformer is securely plugged in.
Verify the main AC power supply is working properly.
Unplug the controller for 3 minutes. Plug the controller
back in. If there is no permanent damage, the controller
will accept programming and resume normal operation.
Reset
If the controller is not working properly,
pressing the Reset button located under
the wiring bay cover will reset the internal
electronics. Date and time will need to be
updated but all watering schedules should
remain intact.
To press the Reset button, carefully insert a
small tool (end of a paper clip, for example)
into the access hole and press the button
until the controller resets.
