Flow problem
Insufficient flow: open a radiator valve.
The circuit is clogged:
Check that the filters are not obstructed and clean them if necessary.
Clean and flush the installation.
No circulation:
Check that the valves and thermostatic valves are open,
Check that the circulating pump is working,
Check the wiring,
Check the pump supply: if the pump does not work, replace it.

SCB-10 blocking codes
A blocking code signals an anomaly affecting the heating system.
Several examples:
The system automatically attempts to correct the error (for example in
the event of a fault related to the flow rate).
The error is still present and the system functions in defect mode (for
example, in the event of a fault affecting the outdoor unit, the backup is
started up).
The system is shut down but automatically switches on again when the
error disappears.
