BC10 adjustments
The boiler is equipped with an 3.0 UBA. This is the brain of the
boiler. The BC10 is located behind the access panel cover.
The BC10 allows you to operate the boiler and to make adjust-
ments in its settings such as the temperature for the DHW.
BC10 overview:
Mains switch (fig. 35, item 1)
Use this switch to turn the boiler on or off.
Reset button (fig. 35, item 2)
When a blinking code is in the display, it is possible to try and
restart the boiler by pressing this button.
Chimney sweep button (fig. 35, item 3)
When this button is pressed for 2 to 5 seconds, the boiler will
operate at full power for central heating. A dot is visible in the
lower right hand corner of the display when the chimney sweep
mode (service mode) is active (see fig. 36). When the set flow
temperature is reached within 30 minutes then the boiler
returns to normal operation. Otherwise the boiler will return to
normal operation after 30 minutes. Once the boiler is in service
mode you can terminate the service mode by pressing the
chimney sweep button for 2 to 5 seconds again.
Emergency operation
By pressing the chimney sweep button for longer than
5 seconds, the emergency operation is activated. The boiler
will burn continuously for 24 hours according to the set flow
temperature. Warm water is available during emergency oper-
ation.
The dot in the lower right hand corner of the display will blink
(see fig. 37).
z
Press the chimney sweep button until the blinking dot
disappears from the display to end the emergency opera-
tion.
Service Button (fig. 35, item 4)
Pressing the 'service button' repeatedly allows you to scroll
through this menu. The menu shows the flow temperature,
system pressure and the current operating status.
