Congratulations . . . you have chosen one of the most advanced irrigation
controllers available. Rain Master has taken great pride and patience in
developing and building the most trouble-free controllers in the irrigation
industry. Your RME HAWK has many high-end features. Features such
as accurate, economical flow sensing, and cycle and soak programming are
yours at the press of a button. In addition, your new RME HAWK controller
maintains full support of independent pump and normally closed or
normally open master valves. All this was designed to protect one of our
most precious resources…water… as well as your bottom line!
To take full advantage of the many features available in your RME HAWK
controller, please take a few minutes and read through your User Manual.
For those who do not have the time, a Quick Reference sheet is provided.
This sheet will allow you to perform many of the basic functions required
in programming and operating your controller.

USER PROGRAMMABLE FEATURES (SETUP)
The following features can be easily selected or reconfigured by a single push of a button
(SETUP key)
• Programmable Master Valve allows you to program a Master Valve to go on
by program.
• Programmable type of Master Valve allows you to select either a Normally
Closed Master Valve or a Normally Open Master Valve.
• Programmable Pump allows you to program a Pump (independent of the
Master Valve) to go on by program.
•Programmable stacking or no stacking of programs allows you to have programs
run one after the other (Stack Mode) or at the same time (No Stack Mode).
• Programmable timer delay between stations allows you to program a time
delay from 0 to 255 seconds (4 minutes 15 seconds) to allow slow-closing
valves to completely shut off.
• Programmable security code allows you to enter a 1 - 4 digit number as a
security code which will prevent entry by unauthorized personnel.
•Programmable sensor allows you to have a sensor device enabled or disabled
for each program.
•Programmable alarm allows you to either enable or disable an audible alarm
in the event of a flow limit violation or a field wire fault detection.
•Programmable cycle and soak allows you to select each program to be either
a cycle and soak program or not.
• Programmable flow allows you to enable or disable the flow sensor features.
•Programmable pipe size allows you to select the pipe size for the flow sensor.
•Programmable main line flow limit allows you to set an upper flow limit from
1 to 999 GPM.This limit defines the maximum allowable controller flow
for scheduled irrigation.

•Programmable unscheduled flow limit allows you to setup an upper flow limit
from 0 to 999 GPM.This limit defines the maximum allowable flow when
there is no scheduled irrigation, e.g.. usage of manual quick coupler devices.
•Programmable flow check delay allows you to set up a delay after any station
changes, from 1 minute to 6 minutes, during which time no flow limits are
checked.
• Total Gallons allows you to view the total accumulated gallons and to clear
the total accumulated gallons.
•Programmable flow percentage allows you to set up a global percentage from
5% to 80% which will be used as an adjustment on all station upper flow
limits.
• Programmable station upper flow limits allows you to individually set an
upper flow limit from 0 GPM to 500 GPM for each station or to run a
watering profile during which the upper flow limit for each station will be
automatically set based on the measured flow and the global programmable
flow percentage.

MOUNTING AND INSTALLATION
CONTROLLER PLACEMENT
WARNING: Do not drill holes in the controller's case. It has all the holes necessary
for mounting it on a wall or pedestal. Drilling holes in the unit will cause metal
chips to mix with the electronics and this will cause the unit to malfunction. If, for
some reason, it is absolutely necessary to drill additional holes in the unit, carefully
remove all the electronics prior to doing so.
Controllers are suitable for indoor/outdoor environment. It is lockable, dust-free and rain
resistant. Outdoors the controller should be placed in a shaded and dry environment not
subject to direct sprinkler spray or continuous heavy moisture. Additionally, a pedestal
(PED 1) is available for outdoor controllers; contact your Rain Master distributor.
MOUNTING THE CONTROLLER
1. On an upright, flat and secure surface, place the mounting bracket at eye level and
fasten securely.
2. Mate the bracket on the back of the controller to the mounted bracket and hang the
controller.
3. Secure the bottom of the controller by placing a screw through the hole located in its
back wall at bottom center.
CONTROLLER CONNECTIONS – AC POWER
1. Refer to Figure 1 - Power and Field Wiring.
2. Mount controller.
3. Place Rain Switch in “No Watering” position.
4. Remove lower panel.
5. Using #10-gauge or heavier copper wire, connect ground screw to ground rod or
grounded water pipe using a ground rod clamp. The wire should be as short as possible
with no sharp bends or kinks. If multiple clocks are being installed in the same
location, use a ground rod for each and contact the factory for the RMIS pamphlet
on proper grounding techniques.
6. Thread condulet onto transformer.
7. Connect supply line grounded conduit to condulet.
8. Connect 120 V 50/60Hz supply line to transformer wires within the condulet
Install gasket and cover onto condulet with 2 screws.
9. Follow all appropriate electrical wiring codes.
10. Replace the lower panel and place the Rain Switch in “Automatic Watering” position
after field valve wiring is complete.

ELECTRICAL GROUNDING FOR THE CONTROLLER
Proper electrical grounding is required to ensure safety to you, as well as to protect the
controller electronics in the event of electrical line surges or lightning. In areas where
lightning is a common occurrence, it is strongly recommended to use the HAWK model
HK-T.
Grounding Instructions
1. Mount the controller as close as possible to the grounding rod, so that the #10 grounding
wire from the controller to the ground rod is as short as possible. Ensure the grounding
wire is free of nicks and bends.
2. Use a grounding rod clamp to secure grounding wire to grounding rod. Be sure all
surfaces are clean of oxides and dirt, and that all connections are solid and secure.
3. In areas of very dry soil or sand, it may be necessary to "Dope" the grounding rod.
Contact your Rain Master distributor or Rain Master for grounding pamphlet,
“RMIS Grounding”.
4. Should the 8' grounding rod not penetrate completely into the soil it is acceptable to
put it into the ground on a slight angle. It is important that the rod be a full 8' into
the ground, with only enough of the rod showing to clamp the wire on. Should other
grounding installation requirements be necessary, contact your distributor or Rain Master.
Note: It is important to check the resistance periodically to ensure it is not greater than
10 ohms. Contact your Rain Master Distributor for details.
