Operating the controller,
Using the Sensor Option
The controller allows you to connect a sensor that
can disable watering. When a sensor is connected to
the controller and it suspends watering, the sensor
light on the front panel illuminates.
To enable the sensor,
Set the sensor switch to ACTIVE.
The controller operates as usual until the sensor
suspends watering and the SUSPENDED BY
SENSOR light is on.
Note: When no sensor is attached, the jumper cable
supplied with each controller must be in place,
connecting the SENSOR terminals on the controller
circuit board. If you set the SENSOR switch to
ACTIVE with neither a sensor nor the jumper cable
connected, the controller cannot operate the valves
and no watering will occur.
Fuse Detection
The controller display will show FUSE if a fuse is
missing or blown.

Using the Diagnostic Circuit Breaker
The controller is equipped with a circuit overload
protection system. This system causes the controller
to skip over a station that has an electrical short
circuit, rather than blow a fuse which would shut
down the entire system. When the controller tries to
start a station that has a short circuit, the electronic
circuit breaker senses the short circuit and skips that
station. The controller skips to the next station, but
flashes the skipped station number and FAULT in
the display.
Once you have corrected the problem, push the
FAULT RESET key to clear the flashing fault
indicator.
Note: The diagnostic circuit breaker allows detection
on all stations, as well as the master valve.
Replacing the Battery
1. Open the cabinet door.
2. Release the latch by sliding it to the left and swing
the panel open.
3. Open the battery cover on the back of the
faceplate. Remove the 9-volt battery.
4. Install a new rechargeable 9-volt battery and
close the cover.
5. Close the faceplate.
IMPORTANT! Use only rechargeable batteries in
your controller. Non-rechargeable batteries could
damage the controller or be a fire hazard.
