Pentair VT 5600SXT How to Program: A Simple Step-by-Step Guide

The Pentair VT 5600SXT water softener valve is a popular choice for homeowners due to its reliable performance and easy-to-use digital control. However, if you’re new to the system, you may find programming it a bit confusing. In this guide, we’ll walk you through how to program the Pentair VT 5600SXT step by step in clear, easy-to-follow language.

What You’ll Need

Before you begin, make sure:

• Your unit is properly installed and connected to power

• Water is flowing through the system

• You have access to the owner’s manual (optional but helpful)

Understanding the Control Panel

The 5600SXT digital controller has a bright LCD screen and four buttons:

• Up (↑)

• Down (↓)

• Next

• Regen (used to start manual regeneration)

Each button plays a key role in programming your softener. Let’s get into the steps!

Step 1: Enter Programming Mode

1. Hold the “Next” and “Up” buttons together for 5 seconds until the display changes.

2. You’re now in the master programming mode.

Step 2: Set the Time of Day

1. Press the “Next” button until you see the time setting screen.

2. Use the Up (↑) and Down (↓) arrows to adjust the hour.

3. Press “Next” again to change the minutes.

4. Set it to the current time and press “Next” to confirm.

Tip: Make sure you set AM/PM correctly for proper regeneration timing.

Step 3: Set the Water Hardness

1. After the time setting, you’ll see “HARD” or “HD” on the screen.

2. Use the arrows to set your water hardness in grains per gallon (gpg).

   • Example: If your water test shows 20 gpg, set it to 20.

3. Press “Next” to continue.

Step 4: Choose the Regeneration Cycle Type

The 5600SXT supports metered or time clock regeneration:

• Metered: Regenerates based on water usage.

• Time Clock: Regenerates on a fixed schedule (not recommended for variable usage).

1. When the screen shows “DF GAL” or “DF Ltr”, this lets you choose gallons or liters.

2. Then it will show “VT” – valve type. Make sure this is set to “dF1b” for most softeners.

3. Use the arrows to select the right option, then press “Next”.

Step 5: Set Capacity and Reserve

1. The display will now show “C” – the capacity in grains.

   • Example: A common setting might be 32,000 grains.

2. Next, set the “RS” (reserve) setting:

   • SF (safety factor): Good for average use.

   • RC (fixed reserve): Set manually in gallons.

Tip: Most homeowners use SF with a 10-20% reserve.

Step 6: Regeneration Time

1. The screen will show “DO” (days override).

   • This is the maximum days before the system regenerates, even if not needed.

   • Set it to 14 as a general recommendation.

2. Now set the “RT” (regen time) – typically 2:00 AM.

   • Use the arrows and press “Next” to confirm.

Step 7: Finalize and Exit

Once you’ve gone through all the settings:

1. Press and hold “Next” to save and exit programming mode.

2. The screen will return to the main display showing time Pentair vt 5600sxt how to program and remaining gallons.

Extra Tip: Manual Regeneration

If you want to start a manual regeneration:

• Press and hold the “Regen” button for 5 seconds.

• The system will begin the cycle immediately.

Common Programming Mistakes to Avoid

• Setting the wrong hardness value (always test your water first)

• Forgetting AM/PM in time settings

• Skipping the capacity setting, which affects softening efficiency

FAQs About Pentair VT 5600SXT Programming

1. What is the default factory setting for the Pentair VT 5600SXT?

The factory settings typically include:

• Time: 12:00 PM

• Hardness: 20 gpg

• Capacity: 32,000 grains

• Regeneration time: 2:00 AM
  However, it’s important to adjust these settings based on your specific water conditions and household usage.

2. How often should the system regenerate?

If you’re using a metered setup, the system will regenerate based on your actual water usage. However, the “Days Override” (DO) setting ensures it regenerates at least every 14 days, even if the water usage is low. You can adjust this depending on your preference and water quality.

3. What happens if I enter the wrong hardness level?

Setting the wrong hardness level can lead to poor softening Pentair vt 5600sxt how to program performance or unnecessary regenerations. If the hardness is set too low, hard water may pass through. If it’s too high, the unit might regenerate more often than needed. Always test your water and input the correct grains per gallon.

4. How do I reset the Pentair VT 5600SXT to factory settings?

To reset the unit:

1. Unplug the unit from the power source.

3. Plug the unit back in while still holding the buttons.

4. Wait until the screen flashes — this means it’s reset to factory defaults.

Note: You will need to reprogram all settings after a reset.

5. Can I switch from time clock to metered regeneration later?

Yes, you can change the regeneration type at any time by entering the programming mode and adjusting the “DF” setting. Just be sure to recheck your capacity and reserve settings after making the change to ensure everything runs efficiently.
