How to Fix / Troubleshooting
Safety: No special safety concerns; this is a programming issue.
- Set correct time: Adjust the current time and day on the Cillit controller.
- Set regeneration time: Program regeneration to occur at a low‑usage time (e.g., 2:00 AM).
- Check backup battery: If time is lost during power cuts, replace the Cillit control board backup battery.
- Verify mode: Ensure the unit is not set to immediate regeneration mode if you want delayed regeneration.
