Rain-Delay #

The Rain Delay button can be used to delay your sprinkler controller from watering for a duration of
1 to 32 days. At the end of the selected rain delay amount of time, automatic watering resumes.

  1. Make sure the controller is set to AUTO.
  2. Press the Rain Delay button to automatically delay watering for 24 hours.

Note: If a longer Rain Delay is desired, press the rain delay button repeatedly or turn the dial until the desired number of delayed days is reached.

  • While in rain delay mode, the controller will display the number of remaining rain delay days or hours.
  • To cancel a rain delay, press the CLEAR button and the watering schedule will resume.
  • To activate or deactivate the rain sensor terminals, press and hold the RAIN DELAY button for 5 seconds.

Note: This feature is helpful for bypassing the sensor if watering is needed before the sensor is dry and watering is resumed.

Budget #

The water budgeting feature makes it easy to change all of your run times without having to change them one by one. This is perfect for adjusting all zones for seasonal changes.

The adjustment range is from 10% to 200% by increments of 10%. The default value is 100%, which means your controller will run each zone for exactly the number of minutes you entered as the run time. The budgeting will remain at the adjusted range until you change it.

  1. Turn the dial until the selection box is on budget.
  2. Press the dial. You will now see numbers flashing. Note: 100 is the default number.
  3. To adjust, turn the dial to the desired budget percentage.
  4. Press the dial to confirm your selection.

Adjusting the budget will adjust all of the run times in a program by the percentage chosen.

Example: If you have zones set up to water for 10 minutes and you adjust your budget from 100% to 150%, those same zones will water for 15 minutes without having to change each run time.

If you are setting up additional programs (A, B, C, or D), press the PROG ABCD button until the desired program is displayed and repeat this process.

Manual #

Rain Sensor #

Connect the rain sensor wires to the wiring terminal ports labeled “Sensor”.

Note: Refer to your rain sensor manual for specific wiring instructions.

Rain Sensor Bypass #

This sprinkler controller is equipped with a sensor override “on/off”. This is for use during maintenance and repairs, so the sprinkler controller can be operated even if the rain sensor is in active mode. To override the sensor, press and hold the Rain Delay button for 5 seconds.

The display will show SENS and OFF or SENS and ON.

Important: If the rain sensor is “on” and no sensor is connected, the sprinkler controller will not operate. To resume sprinkler controller operation press and hold the Rain Delay button for 5 seconds or reconnect the jumper wire to the sensor terminals

Pump Start & Master Valve #

This sprinkler controller allows a master valve or pump start relay to operate whenever a station is on.

Note: If you are activating a pump from this controller, you must purchase a Pump Start Relay. From the pump start relay (or master valve); connect one wire to the “Pump” terminal and the other wire to the “Common” terminal.
