Pump Control Option
By default, the pump control circuit is activated simultaneously with any
automatic or manual valve station operation. When pump operation is not
required for specific valve stations; e.g., drip irrigation, the pump control
circuit can be easily disabled as needed.
Note: The Pump control option applies to the selected valve station
regardless of its Program assignment.
1. Place the Function switch in the Set Programs position.
2. Turn the Dial to select the appropriate valve station number.
3. Press the Manual button: P:On (Pump On) will be displayed.
4. To disable the pump control circuit from the valve station, press the
button to display P:OF (Pump Off).
5. Repeat steps 2–4 for additional valve stations as required.
6. Return the Dial to the Current Time position.
7. Return the Function switch to the Run position.
Diagnostic Circuit Breaker
The prompt “FUS” and the malfunctioning valve station number will
be alternately displayed with the current time. The valve station will be
bypassed during the watering cycle, enabling all remaining valve stations
to run as scheduled.
With the Dial set in the Current Time position, press any button to clear
the “FUS” display.
Important: Determine the cause of the malfunction and
take corrective action as necessary. Clearing the display will not
resolve the problem.
Fuse Replacement
Caution: The 2.0A safety fuse protects the transformer from
damage due an excessive current load (short circuit) condition.
Locate and eliminate the cause of the problem before replacing the fuse.
For continued protection against risk of fire, replace only with the same
fuse type and rating.
1. Disconnect power to the controller.
2. Carefully remove the safety fuse from the terminal board (see Figure
3, page 4 for fuse location).
3. Install a new 2.0A slow-blow fuse, ensuring that it is properly seated
