How to fix Lost Schedules & Clock Drift on Clipsal C-Bus 5080CTC

Expert diagnostic guide and repair services in the Sydney CBD.

⚠️ Discontinued Unit — No Manufacturer Support

The C-Bus 5080CTC is a discontinued colour touch screen controller for Clipsal C-Bus systems. These legacy units are no longer supported by Schneider Electric / Clipsal and require specialist diagnosis for repairs or replacement.

Direct Answer: C-Bus 5080CTC Colour Touch Screen (Legacy) — Lost Schedules & Clock Drift

If schedules are failing or the time is drifting, the internal RTC (Real Time Clock) battery backup has likely failed. Older modules lose their timekeeping ability when power fluctuates.

Step-by-Step Diagnostic Steps

  1. Connect to the system using the programming toolkit.
  2. Check the current system time and date against actual time.
  3. If the time resets to a default (e.g., 01/01/2000) after a power cycle, the battery is dead.
  4. Some batteries are soldered onto the PCB and cannot be easily replaced.
  5. Consider upgrading to an Ethernet gateway that syncs via NTP (Network Time Protocol).
