[0/a/\| [3/0/5|
1)
Operating phase:
The boiler cannot start up temporarily after a DHW request has ended.
[0/c/\| [2/8/3|
1)
Pre-operative phase:
The boiler prepares for a burner start-up whenever a heat demand or a
DHW request arises.
[0/e/\| [2/6/5|
1)
Readiness for operation:
The boiler is in standby mode. There is a current heat demand, but too
much energy has been supplied.
[0/h/\| [2/0/3|
1)
Readiness for operation:
The boiler is in standby mode. There is no current heat demand.
[0/l/\| [2/8/4|
1)
Ignition phase:
The gas valve is activated.
[0/u/\| [2/7/0|
1)
Start-up phase:
The boiler starts up after activation of the mains power supply or comple-
tion of a system reset. This code is displayed for a maximum of
4 minutes.
[0/y/\| [2/0/4|
1)
Operating phase:
The flow temperature sensor has detected that the current flow tempera-
ture is higher than the flow temperature setting on the BC10, or 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.
The room temperature is not possibly
reached.
[0/y/\| [2/7/6|
Locking fault:
The flow temperature sensor has measured a current flow temperature
higher than 203 °F (95 °C).
The room temperature is not possibly
reached.
[0/y/\| [2/7/7|
Locking fault:
The safety temperature sensor has measured a current flow temperature
higher than 203 °F (95 °C).
The room temperature is not possibly
reached.
[0/y/\| [2/8/5|
Locking fault:
The return temperature sensor has measured a current return tempera-
ture higher than 203 °F (95 °C).
The room temperature is not possibly
reached.
[1/a/\| [3/1/6|
Blocking fault:
The flue gas sensor temperature is too high.
No heating operation and no DHW.
[1/l/\| [2/1/1|
Locking fault:
There is no connection between contacts 78 and 50 of the UBA 3 instal-
lation base.
No heating operation and no DHW.
[1/u/\| [3/1/7|
Blocking fault:
The flue gas sensor contacts have shorted.
No heating operation and no DHW.
[1/y/\| [3/1/8|
Blocking fault:
The flue gas sensor contacts are open.
No heating operation and no DHW.
[2/e/\| [2/0/7|
Locking fault:
The system pressure is too low (less than 3 psi [0.2 bar]).
No heating operation and no DHW.
