MANUAL CONTROLLER
INSTALLATION AND OPERATING GUIDE
MODEL HRM-12
STEP 1: PEDESTAL MOUNTING
The pedestal should be mounted on a level concrete base about lOxlOx8
The HRM-12 is a 12 station controller that can be set to water from twenty-four
times a day to once every two weeks. The watering time can be adjusted from
approximately 5 to 60 minutes for each circuit. The controller is in a weather
resistant case that can be mounted on a two inch pipe pedestal or against a wall
with wood screws. The controller has a lockable cover, with two keys, to
discourage unauthorized adjustment.
STEP 1: WALL MOUNTING
Open the cover of the controller and open the panel by unscrewing the latch
screw. (See Figure 3). Disconnect the wiring connector and rotate the panel until
it can be lifted up off the hinges. Punch through the three mounting holes so No. 8
wood screws can pass through the back of the case. Place the empty controller
box against the wall and screw three No. 8 wood screws through the back and
into the wall.
NOTE: To install the timer on a plaster or masonry wall, use plastic or
lead shields to secure screws.
inches with the top of the concrete base at least two inches above ground
level. Position a 2 inch elbow and a 1/2 inch conduit in the concrete form as
shown. The elbow and conduit must be in position before the concrete is
poured. Four hold down bolts must be positioned in the concrete before it
sets. Feed the 12OV AC power wires through the conduit. Screw the 2 inch
pedestal pipe into the controller and run the ring nut up tight against the
controller to lock its position on the pedestal. Do not use pipe dope as a
sealing compound.
Lower the controller, with pedestal attached down upon the concrete
base, at the same time feeding the conduit with power wires inside into the
controller’s conduit opening. Secure the conduit to the controller and
tighten pedestal base nuts.
STEP2: CONNECT THE TRANSFORMER
Open the cover of the controller and
loosen the latch screw (See Figure 3) to
swing out the control panel. Remove the
STEP 2: CONNECT THE TRANSFORMER
This connection should be made by a licensed electrical contractor in
accordance with all requirements of the National Electrical Code and
applicable state and local codes.
Using the 7/8 inch conduit hole in the bottom of the cabinet, run the 120V AC
power wires into the wiring cavity. Remove the Caution High Voltage plate and
use wire nuts to connect the white wire as the common, the black wire as the
power, and the green wire as earth ground.
CAUTION: Make sure the 120V circuit breaker is turned to the off
position prior to wiring the controller.
After the electrical wires are attached, replace the caution plate before turning
the circuit breaker on.
Caution High Voltage plate and use wire
nuts to connect the white wire as the
common, the black wire as the power, and
the green wire as earth ground.
CAUTION: Make sure the 120V circuit
breaker is turned to the off position prior
to wiring the controller.
After the electrical wires are attached,
replace the caution plate before turning the
circuit breaker on.
STEP 3: CONNECT THE VALVE WIRES
Run the valve wires through the 2 inch
pedestal pipe and connect them to the
terminal strip inside the controller. Connect
the wire from valve No. 1 to the terminal
marked No. 1, valve No. 2 to terminal No. 2,
etc. Connect the valve common wires to any
terminal marked C. (See Figure 2).
STEP 3: CONNECT THE VALVE WIRES
Run the valve wires through the 2 inch hole and connect them to the terminal
strip inside the controller. Connect the wire from valve No. 1 to the terminal
marked No. 1, valve No. 2 to terminal 2, etc. (See Figure 2). Connect the valve
common wires to any terminal marked C. If the valve wires are to be run through
conduit, a conduit junction box can be used by placing a reducer from 2 inch on
one end and screw the 2 inch reducer into the hole.

STEP 1: VALVE WIRING
Wiring to the valve can be placed underground alongside the pipes. Use
approved underground type wire and be sure all splices are soldered or
jointed with wire nuts and sealed with vinyl cement or other suitable waterproofing cement. Use 18 gauge solid wire plastic jacketed thermostat control
wire for runs not over 800 feet and 14 gauge over 800 feet. This wire is
available from your dealer in 2, 3, 4, 5, 6, 7 and 8 color coded wires.
IMPORTANT: The power rating of the transformer is 40VA. at 24V
and is protected by a circuit breaker. Do not connect more than 2
valves to each circuit or use a valve that requires more than 1 amp
at 24V AC.
If a pump start relay is required, it must be connected to the terminal
marked NO. P and to one of the common terminals. The relay coil should be
rated for 24V AC, 60 Hertz at 9.0 VA maximum.
NOTE: Due to varying regulations check your local codes.
It is possible to change the HRM-I2’s day changeover time from 12:OO AM
(midnight) to 12:OO PM (noon). This will alleviate any watering problems
that arise if there is a need to water past midnight.
INSTRUCTIONS
To have the day changeover occur at 12:OO PM (noon):
1. Lay the controller down on a flat surface.
CAUTION: Controller must lay flat.
2. Loosen the screw that holds the “set time” wheel about two (2) turns.
Do not remove the screw.
3. Pick up the numbered dial plate and gently rotate it until the notch at
12:OO PM (noon) is aligned with the black index pin.

4. Set the dial plate into position and tighten the screw. Do not overtighten.
REMINDER: Be sure that your combined watering times end
before the day changeover occurs. Any remaining cycles will be
CANCELLED at that time.
CAUTION WHEN USING A PUMP
If a pump is being used and the watering cycle is cancelled, the pump
will remain ON. This will deadhead the pump and result in pump damage.

STEP 1: SET TO CURRENT TIME OF DAY
Rotate the day dial (1) clockwise until the current time of day lines up with the point
of the day switch arm (2).
STEP 2: TO SET THE PROGRAM DIALS (Skip-a-day)
Rotate the program 1 dial (3) clockwise until the current day lines up with the center
of the program switch arm (4). Program 2 dial (5) will rotate with the program 1 dial.
STEP 3: TO SET WATERING START TIME
Pull the day dial’s switch lug (6) out at the time of day watering is required to start.
More than one switch lug may be pulled out for multiple waterings in a 24 hour period.
All other switch lugs must be pushed in so they will not start to the day switch arm.
STEP 4: TO SET THE WATERING PROGRAM
Pull out program 1 and program 2 dials’ switch lugs (7) representing the days of the
week of watering for both programs. All other lugs must be pushed in so the program
switch arms will not be started on days to be skipped.
STEP 5: TO SET PROGRAM CIRCUIT SWITCHES AND CIRCUIT WATERING
TIMES
Place each of the twelve circuit switches (8) to the desired program: program 1,
program 2, or off. Before adjusting the watering time, place the master switch (9) in
the rain position. Each of the twelve circuits can then be individually adjusted for
watering time. To change the time simply rotate the selected circuit timing knob (IO)
until its raised line matches up with the minutes required on the circuit selector wheel
(11). if while making these adjustments the circuit selector wheel is moved off of its
set point, it must be returned to the set point before placing the master switch to its
automatic position. Rotate the circuit selector wheel clockwise until its pointer lines up
with the solid mark to the left of the set arrow. When the master switch is placed in
automatic, the wheel will move to its set position and stop.
CAUTION: Move selector wheel clockwise only.
NOTE: Watering time must exceed 15 minutes. Otherwise, watering
cycle will immediately repeat.
STEP 6: MASTER SWITCH
For programmed watering, move the master switch (9) to the automatic position. To
shut down the system (rain), move the master switch to the rain position. For manual
watering, move the master switch to the manual position, then move the desired
program circuit switch to the manual position. The selected circuit will run as long as
both switches are in their manual positions. If the master switch is moved back to the
automatic position and an automatic cycle starts with a program circuit switch left in
the manual position, the circuit selector wheel will move past the circuit without
watering.

STEP 7: CIRCUIT BREAKER
A tripped circuit breaker (12) indicates an electrical problem in the wiring to the
valves or in the valve. If the circuit breaker trips, the controller will stop on the circuit
causing the problem. To reset the circuit breaker, push the reset button.
