How to Fix / Troubleshooting
Safety first: No mains work is required for configuration changes.
- Review zone list: In the main controller or app, list all zones and verify each has a unique name and assigned thermostat.
- Re‑assign thermostats: For any zone showing errors, re‑run the zone assignment or binding process so the controller knows which thermostat controls which actuators.
- Check schedules: Ensure each zone has a valid schedule and that there are no overlapping or invalid time entries.
- Controller reboot: Power cycle the main controller or gateway to clear any temporary configuration glitches.
- If errors persist: A firmware update or, in rare cases, replacement of the zoning controller may be required.
