HOW THE ELECTRONIC CIRCUIT
BREAKER WORKS
The controller is equipped with an electronic circuit breaker. If the
controller detects a short circuit, the shorted station (valve) will be
turned off automatically. The display will then alternately flash “FUSE”
and the shorted station number or "0" for the master valve. The
controller will continue to automatically water the other stations and
the following watering cycles until the short is repaired.
Common conditions of the electronic circuit breaker include:

“FUSE” and one or more station numbers
alternately flash.
One or more stations are shorted.
Check station(s) for cause of shorted condition. Repair valve(s)
and/or wiring on station(s), and press both Advance buttons at
the same time to clear.
Too many valves are operating at the same time.
Check programs and stations, including master valve for VA
output. Maximum total output is 36 VA (1.5 amps). Reduce
number of valves on at the same time to below maximum output
allowance. Press both Advance buttons at the same time to clear.
A short circuit has occurred with a time duration too short for the
controller to determine the station.
Check valve wiring for breaks in the insulation which may cause
a station output to short to common. Press both Advance buttons
at the same time to clear.
“FUSE” displays without any station numbers.
A transient surge has spiked the line.
Press both Advance buttons at the same time to clear.
An overload or short has occurred while the controller is being
activated by a remote control device such as the RVC system.
Press both Advance buttons at the same time to clear.
“FUSE” is alternately displayed with “0” and none of the
stations is operating automatically.
The master valve is shorted. When this occurs, all station outputs
will be suspended until the short is repaired.
Repair master valve, pump start relay and/or wiring, and press
both Advance buttons at the same time to clear.
PROGRAMMING THE
CONTROLLER FOR
WATERING
To set up a regular watering schedule, follow the steps below. This
section covers the following topics:
l
Developing a watering plan
l
Setting the current time and day
l
Erasing any prior programs
l
Setting the station watering time
l
Selecting the days to water

DEVELOPING A WATERING PLAN
Two watering programs are available. Each program can be used for
separate watering requirements. For example, you might use one
program to water the lawn on Wednesdays and Saturdays, and another
program to water trees and shrubs once a week.
The controller is pre-programmed with a 14-day calendar. The calendar
can be changed to a 6-day calendar (see the Advanced Features section,
page 21). The examples in this section assume a 14-day calendar.
WHAT IS A WATERING CYCLE?
Each watering cycle waters all the stations in a program in sequence.
For example, in the sample watering plan shown below, program A has
three watering cycles. Therefore, all four stations in the program are
watered three times each day, first starting at 2
A
.
M

then at 6

and
again at 5

Before you program a watering schedule, decide how to
use each program.
