Operating phase:
Communication test while starting up. This display code flashes five 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.
Operating phase:
2)
The boiler is in flue gas test or service mode.
Operating phase:
2)
The boiler is in heating mode.
Operating phase:
2)
The boiler is in manual operation mode.
Operating phase:
2)
The boiler is in heating mode.
Operating phase:
2)
Pump run-over time via the external hot water cylinder 130 seconds at the minimum speed.
The "Burner" LED (On/Off) is off.
Operating phase:
2)
The switch optimization program is activated. This program is activated if there has been any
demand more frequently than once every 10 minutes. This means that the boiler cannot be
restarted until at least 10 minutes have elapsed since initial burner start-up.
Operating phase:
2)
The boiler cannot start up temporarily after a DHW request has ended.
Pre-operative phase:
2)
The boiler prepares for a burner start-up whenever a heat demand or a DHW request arises.
Readiness for operation:
2)
The boiler is in ready mode. There is a current heat demand, but too much energy has been supplied.
Readiness for operation:
2)
The boiler is in ready mode. There is no current heat demand.
Ignition phase:
2)
The gas valve is activated.
Start-up phase:
2)
The boiler starts up after activation of the mains power supply or completion of a system reset.
This code is displayed for a maximum of 4 minutes.
Operating phase:
2)
The flow temperature sensor has detected that the current flow temperature is higher than the flow
temperature setting on the BC10, or that it is higher than the flow temperature. Calculated
according to heating requirements, or that it is higher than the flow temperature calculated for the
DHW mode.
e
Fault:
2)
The system pressure is too low (less than 0.2 bar).
Function test:
Display test during start-up phase. The display code is displayed for a maximum of 1 second.
10.2

Display codes

The display shows the operating condition (e. g. a fault) by means of two
three-digit codes.
Refer to section 10.3, "Identifying and resetting faults" on page 9 for
further instructions on how to remedy certain faults.
Please contact your heating engineer if you cannot remedy a fault
yourself or if the display shows a code which is not listed in the table.
