Answer / Sheelu Yadav

The issue seems to be related to overloading or a short circuit in zone 8. To fix this, you could consider the following steps:
1. Check for any loose connections or damaged wires in zone 8.
2. Adjust the control circuit to distribute the load more evenly among all zones, possibly by adjusting the time delay for each zone.
3. If the issue persists, it might be necessary to replace the thyrister or the IR lamp for zone 8.
