Reason Connection failure with one of the boilers of the cascade.
Cause:
The unit is programmed in such a way that none of the boilers in a cascade will fire, if one
has a lock-out. One unit has a lock-out and therefore the whole cascade is blocked.
Corrective action:
Troubleshoot the fault of the unit in lock-out.
