Key Features:

  1. On-Demand Regeneration: Unlike traditional timers that regenerate based on a preset schedule, the AT460I-DEMAND regenerates based on actual water usage. This ensures that regeneration happens only when necessary, leading to significant salt and water savings.

  2. Digital Display: The timer features a clear digital display showing the current time, days until the next regeneration, and current flow rates. This offers users a snapshot of system performance at a glance.

  3. Simple Navigation: The interface has a limited set of buttons, making navigation and setting adjustments straightforward even for those who aren't tech-savvy.

  4. Self-Diagnostics: The system continually monitors its operations. In the case of any discrepancies or issues, the timer alerts the user, simplifying maintenance and troubleshooting.

  5. Battery Backup: In the event of a power outage, the AT460I-DEMAND has a built-in battery backup to retain settings and ensure continuous operation.


  1. Efficiency: The on-demand regeneration can lead to significant water and salt savings, reducing both operational costs and environmental impact.

  2. Consistency: By regenerating based on actual usage, the timer ensures consistent water quality.

  3. Ease of Use: The digital interface, straightforward navigation, and self-diagnostics make it easy for users to operate and maintain their water treatment systems.

  4. Durability: The Autotrol brand is known for its robust designs and quality manufacturing. The 460i timer is no exception, offering reliability and longevity.

Installation & Programming:

  1. Installation: Ensure that the timer is connected to the appropriate valve body. Once mechanically connected, plug in the timer to a grounded outlet using the provided transformer.

  2. Initial Setup: Upon powering up, the timer may prompt you for initial settings such as current time, water hardness level, and other specifics relevant to the system it's controlling.

  3. Navigation: Use the up and down arrows to adjust settings, and the "SET" button to confirm choices and move between options.

  4. Manual Regeneration: The timer provides an option for manual regeneration, which can be initiated with a simple button press.

  5. Diagnostics and Alerts: Familiarize yourself with the different alerts and diagnostic messages that the timer may display, as detailed in the product manual.

Remember, it's always best to refer to the official manufacturer's manual and consult with a professional when handling such installations.


  1. Preparation:

    • Turn off the main water supply.
    • Ensure the water softener tank is in the bypass position.
    • Disconnect power from any connected systems.
  2. Mounting the Timer:

    • Align the timer with the mounting bracket on the valve body.
    • Secure it using the provided clips or screws (as per manufacturer's specifications).
  3. Electrical Connection:

    • Connect the timer to the transformer.
    • Plug the transformer into a grounded electrical outlet, ideally one not controlled by a switch to prevent accidental shut-offs.

Programming Instructions:

  1. Power Up:

    • Upon initial power up, the timer will likely enter a start-up sequence. This can include displaying the software version and initiating a self-test.
  2. Set Current Time:

    • Press and hold the "SET" button until the display shows the current time.
    • Use the arrow keys to adjust the time. Once set, press "SET" to confirm.
  3. Set Water Hardness:

    • After setting the time, press "SET" again. The display will prompt for water hardness.
    • Use the arrows to set the hardness level based on your water test results. Confirm with the "SET" button.
  4. Set Regeneration Time:

    • Press "SET" again to enter regeneration time setting.
    • Typically, you'll want to set this for a time when water usage is low (e.g., 2:00 AM). Adjust using the arrow keys and confirm with "SET."
  5. Days Between Regeneration:

    • The timer will automatically calculate the number of days between regenerations based on water usage and hardness. However, you can manually adjust this if required. After setting the regeneration time, press "SET" and adjust using the arrows. Confirm with "SET."
  6. Additional Settings:

    • The 460i might have other customizable settings, like salt efficiency, reserve capacity, etc. Navigate through these settings using the "SET" button and adjust as needed.
  7. Exit Programming:

    • After you've completed all settings, you can either wait for the timer to exit the programming mode automatically after a few seconds or press and release the "SET" button.
  8. Manual Regeneration:

    • If you need to initiate a regeneration cycle manually, there will typically be a button or combination of buttons to press. Refer to the manual for this function.


  • The timer will save settings even if there's a power outage, thanks to its built-in battery backup.
  • Familiarize yourself with diagnostic codes or error messages. The timer has built-in diagnostics and will display specific codes if there are issues.

Always remember that while these instructions provide a general overview, the specifics can vary based on the exact model and setup. Always refer to the manufacturer's detailed manual for comprehensive instructions and safety precautions. If you're unsure about any step, consult with a professional to ensure the correct and safe installation and programming of the system.
