SELECTING THE PROPER LOCATION FOR
YOUR CONTROLLER
Indoor Wall Mount
If possible, always select an indoor location for your controller where you are
assured of maximum protection from environmental hazards, accidents, and van-
dalism. Mount the controller on a solid, smooth surface shoulder high so the
operator can easily see the display and read the faceplate graphics.
Outdoor Wall Mount
The most desirable location is shoulder high on the shady side of a suitable wall.
Avoid concealing the controller behind a shrub or near ground level where it will
be in the direct path of a sprinkler head.
MOUNTING THE CONTROLLER
Wall Mount
Select suitable fasteners such as molly bolts in plaster board, wood screws in
wood, etc. Check to see that the head of the screw will pass through the keyhole
slot in the rear of the case. Use the enclosed template to locate mounting screw
holes.
If additional support is desired, remove lower plate on the enclosure by removing
the screws that hold each side and mount one additional fastener through the
lower hole in rear of housing.
Pedestal Mount
If the unit is to be mounted on a pedestal, follow instructions supplied with the
pedestal.

WIRING
1. Screw a 1/2” condulet to the threaded transformer mounting at bottom of
case feeding transformer leads into condulet. Install and secure rigid conduit or
armored cable as may be required by local electrical codes.
2. Route two wires from 110 VAC source through condulet and connect one
to black transformer lead and the other to the white transformer lead using
approved wire nuts.
To ground the controller, connect the green lead from the transformer (which is
slightly shorter than the black and white leads) to a grounding wire. Grounding
can also be achieved by securing metal conduit to the1/2” condulet.
3. Route the 24 VAC wiring from the valves through the large hole in the
bottom of the case. (NOTE: Check local code for approved method).
Sterling 4, 8, and 12:
One wire is routed from each valve to the correspondingly numbered station
terminal. Valve #1 corresponds with station terminal #1, valve #2 with station
terminal #2, and so on. One common wire is connected in parallel with each
valve and then to the “Common” terminal.
If a master valve or pump start circuit is required, connect one wire to the
“Common” terminal and the other to the terminal marked “Master Valve or
Pump Start”.
Sterling 18, 24, 30, and 36
Route the 24 VAC wiring from the field valves through the large hole in the
bottom of the case. (NOTE: Check the local code for approved method.) One
wire is routed from each valve to the correspondingly numbered pigtail. Valve
#1 corresponds with pigtail #1, valve #2 with pigtail #2, and so on. One com-
mon wire is connected in parallel with each valve and to the pigtail labeled “Com”.
If a master valve or pump start circuit is required, connect one wire to pigtail la-
beled “Com” and the other to pigtail labeled “Master Valve or Pump Start”.

REMOTE CONTROL INTERFACE
The Sterling is designed for direct interface with TRC2remote control system
from Remote Control Technology, Redmond, Washington. The DC1-1 cable in-
cluded with TRC2connects directly to the six pin connector labeled Remote on
the Sterling for quick and easy installation.
When using the TRC2, set the dial on the Sterling at the Rain-Off position. The
controller will disallow operation if the dial is set at any other position.
HOW THE BACKUP SYSTEM WORKS
The Sterling is equipped with a non-volatile memory that retains programmed
information during power outages of any length. There is no need to reprogram
when power is restored.
The controller is also equipped with a time-keeping circuit. A lithium battery en-
ables the time-keeping circuit to maintain accurate time during power outages of
any length.
If the power is restored during the time a watering cycle is normally under-way,
the controller will resume operation at the station normally running at the time
of power restoration.
Changing the Battery
Although the lithium battery has a potential life of 10 years, a high temperature
environment may necessitate that it be replaced more frequently. If the controller
fails to maintain current time during a power outage, the battery should be re-
placed.

The battery is kept in a clip holder that is mounted to the rear side of the circuit
board and is easily replaced as follows:
1. Shut off the power supply to the controller.
2.
3.
4.
5. Re-fasten the main panel and the lower plate to the enclosure.
6. Re-apply power to the controller
7. Enter current time and day.
ELECTRONIC CIRCUIT BREAKER
The Sterling is equipped with an electronic circuit breaker. If the controller de-
tects a short circuit at a station (valve), it will shut the station off and the dis-
play will alternately flash “FUSE” and the station number or “0” for the master
valve. The controller will continue automatic operation at the other stations.
During future watering cycles, the controller will skip over the short¬ed station
until the short is repaired.
To clear the electronic circuit breaker, press the CLEAR key after you have in-
vestigated and corrected the cause of the short.
Remove the lower plate by removing the two screws that fasten it to the
controller enclosure.
Remove the four screws that fasten the main panel to the enclosure. Then,
maintaining a grasp on the panel, lower it about one inch and tilt the top
toward you to gain access to the battery holder on the rear side.
Remove the battery from the clip holder and replace it with a Panasonic 3M
BR2325, or equivalent.

Common conditions of the electronic circuit breaker include:
CONDITION:
CONDITION:.
CONDITION:
Fuse and one or more stations alternately flash.
Cause: Shorted solenoid coil and/or a short in the valve
wires.
Cause: Too many valves are operating at the same time.
No more than three valves (including master valve) should
operate simultaneously.
Fuse displays without any station numbers.
Cause: A transient surge has spiked the line. Press
CLEAR.
Cause: An overload has occurred for too short a dura-
tion for controller to determine the station number. Press
CLEAR. If condition repeats during future cycles,
activate a System Check short duration cycle and mon-
itor display to determine which station is energized when
Fuse appears on the display. Carefully check valve wiring
for broken insulation and other conditions that may cause
intermittent short.
Fuse is alternately displayed with 0and none of the
stations are operating automatically.
Cause: Short in master valve or pump start circuit. Check
solenoid coil of master valve, pump start relay, and/or
wiring. Press CLEAR after repair is made.

•
Up to nine cycle starts per day in all six programs; or loop watering optional
in all six programs for unlimited cycles.
Station timing adjustable from 1 minute to 24 hours in one minute incre-
ments. Seconds/minutes time base optional in all six programs.
Watering calendar factory set at 7 days. For “skip day” scheduling (every
other day, every third day, etc.) the watering calendar can be changed to any
length between 1 and 32 days.
Single program option that gives you the flexibility of having two or more
programs scheduled, but limiting automatic operation to only that program
at which the dial is set.
