Comprehensive Step-by-Step Guide: Programming a Clack Water Softener Valve (Velora Water Technician Field Manual – WS1 / WS1.25 / CI / Similar Models)
Clack Corporation Water Softener Valve, Iron Filter Valve, Bypass Valve

This includes safe general parameters for a typical household (3–5 people, 150–300 gal/day, 1 cu ft resin) plus hard resets, factory resets, and little technician secrets for troubleshooting and advanced use.


Safety & Prep Tips:

  • Bypass the valve initially.

  • Confirm resin volume, piston, injector, and media.

  • Use your water testing checklist.

  • Charge backup battery for 24+ hours.


1. Basic Navigation & Buttons

  • SET CLOCK: Set time.

  • NEXT (↑ or ▶): Advance.

  • DOWN (▽): Decrease.

  • REGEN: Manual regen.

  • Advanced: Hold NEXT + DOWN (or NEXT + UP) for 3–5 seconds.


2. Set Time of Day

  • Press SET CLOCK → Adjust hour/minutes → Save. Typical: Regeneration at 2:00 AM.


3. OEM / Advanced Programming (Core Setup)

Enter with NEXT + DOWN for 3–5 sec.

Safe General Parameters for Typical Household (1 cu ft resin):

  • Valve Type: WS1 (or 1.25).

  • Treatment: SOFTENING.

  • Brining: dn (Downflow).

  • Refill: Post (or Pre).

  • Hardness: Compensated (raw gpg + ~5 gpg per ppm iron). Example: 15 gpg + 1 ppm iron → 20 gpg.

  • Capacity: 24,000 grains (efficient ~80% of rated).

  • Regen Mode: AUTO (metered).

  • Day Override: 7–14 days (shorter for iron/tannins).

  • Salt Dosage: ~9–10 lbs per cu ft.

  • Cycle Times (downflow):

    • Backwash 1: 8 min

    • Brine Draw: 60 min

    • Backwash 2: 6–8 min

    • Rinse: 4–6 min

    • Fill: Adjusted for salt.

How to Perform: Use arrows to adjust, NEXT to advance, REGEN to exit/save.


4. Installer Settings

Enter via NEXT + UP (or manual). Confirm hardness, reserve (~20–30% daily use), override.


5. Hard Resets & Factory Reset (Key Technician Secrets)

  • Quick Electronics Reset / Re-Sync (after maintenance or errors): Hold NEXT + REGEN for 3–5 seconds. Display flashes, shows software version, returns to service position. Alternative: Unplug power jack (black wire) from board, wait 1–2 minutes, plug back in.

  • Master / Factory Reset (wipes programming to defaults): Press NEXT + DOWN to reach Service/OEM screen. Then press UP + DOWN simultaneously to reset. Valve returns to basic defaults — re-program from scratch.

  • Unlock Locked Valve (common after failed attempts): Press DOWN, NEXT, UP, SET CLOCK in sequence. Then try advanced mode again.

  • Double Regeneration: Press REGEN once (REGEN TODAY flashes), then hold REGEN 3+ seconds for immediate full cycle.


Technician Secrets & Pro Tips:

  • Secret Diagnostics Mode: Hold UP + DOWN for 3 seconds (may need unlock first). Press again for Valve History (usage stats, error logs, regen counts — gold for troubleshooting).

  • After any drive/motor work: Always do the NEXT + REGEN reset to re-establish piston position.

  • Error Code Fix: Most errors (motor, position) clear with quick reset or power cycle. Persistent? Check seals/piston for debris.

  • Salt Efficiency Hack: Set capacity conservatively (e.g., 24k grains) and use lower salt (6–8 lbs/cu ft) for eco setups.

  • Iron/Tannins/Silica: Shorten override to 3–7 days + consider specialty resin.

  • Pro Move: Take photos of settings screen before/after. Document in your checklist.


6. Manual Regeneration Test

  • Press REGEN → Hold for immediate start.

  • Observe full cycle (listen for brine draw suction).


7. Post-Programming Verification

  • Full regen + pre/post water tests (hardness <1–3 gpg).

  • Document everything.
