Operating phase:
Communication test while starting up. This display code flashes 5 times
within 5 seconds while starting up to indicate that the communication
between the UBA 3 and the BC10 basic controller is being tested. If a
new UBA 3 or a new KIM was fitted, this code will flash for max. 10
seconds.
Blocking fault:
If this code continues to flash on the display, there is a fault in the
communication between the UBA 3 and the BC10 basic controller.

Operating phase:
The flow temperature sensor has detected that the current flow
temperature is higher than the flow temperature setting on the BC10, or
1) that it is higher than the flow temperature calculated according to the
heating curve, or that it is higher than the flow temperature calculated
for the DHW mode.
