2 Information about the product
The BC10 base controller enables the operation of the
standard functions of Buderus heating systems equipped
with the Energy Management System (EMS)1) directly at
the boiler.
Various programming units can be used in conjunction
with the base controller, e.g. for convenient regulation of
room and DHW temperature or for using heating
programs.
The BC10 base controller must be fitted to the boiler
itself.
2.1 EU Declaration of Conformity
The design and operation of this product conform to
European Directives and the supplementary national
requirements. Its conformity is demonstrated by the
CE designation. You can call up the Declaration of
Conformity for this product at the internet at
www.buderus.de/konfo or request it from your local
Buderus sales office.
2.2 Correct use
The BC10 base controller must only be used for the
operation and control of Buderus heating systems.
BAlways use this appliance correctly and in conjunction
with the specified control systems.
BObserve all country-specific regulations and standards
during installation and operation.
2.3 Cleaning the base controller

3 Operating the base controller
The BC10 base controller enables the operation of the
standard heating system functions. For this, it makes the
various functions available, including:
• Switching the heating system ON and OFF
• DHW temperature default and maximum boiler water
temperature in heating mode
• Status display

3.2 Switching ON and OFF
BTo switch ON, set the ON/OFF switch [1] to “1”.
This switches ON the entire heating system. The status
display on the base controller illuminates and shows
the current boiler water temperature in °C.
BTo switch OFF, set the ON/OFF switch [1] to “0”.
Fig. 2 Switching the base controller ON and OFF
3.3 Selecting the maximum boiler water
temperature for heating mode
At the “maximum boiler water temperature” rotary
selector [1], you can set the upper limit temperature for
the boiler water in heating mode. This limit will not apply
to DHW heating.
Fig. 3 Rotary selector for maximum boiler water
temperature in heating mode
DANGER: Risk to life from electric shock!
BIf a risk becomes apparent, isolate all
poles of the heating system or isolate it
from the power supply via circuit breaker/
fuse.
Explanation
0Heating operation is switched OFF (poss. only
DHW operation).
30 – 901)
1) In conjunction with the RC3x programming unit, always select
“Aut”.
The temperature is set permanently at the BC10
and cannot be changed at the programming unit.2)
2) All programming unit control functions (e.g. heating program,
summer/winter changeover) remain enabled.
Aut The temperature is established automatically with a
programming unit (e.g. RC3x) using the heating
curve. If no programming unit is connected, the
maximum boiler water temperature is 90 °C.2)
Tab. 2 Settings at the “maximum boiler water
temperature” rotary selector
If central heating is switched on and heat is
demanded, then the LED below the rotary
selector illuminates.

3.4 Selecting the set DHW temperature
The “set DHW” rotary selector [1] enables you to specify
the required DHW temperature in the DHW cylinder.
Fig. 4 Set DHW rotary selector
3.5 “Burner” LED (ON/OFF)
The LED signals the burner status.
Fig. 5 “Burner” LED (ON/OFF)
DHW is always heated at the maximum
permissible boiler water temperature.
Explanation
0No supply to radiators (exclusively DHW heating).
Eco 1)
1) This function is optimised for appliances with integral DHW
heating (combi boilers, e.g. GB132T). If a programming unit is
installed (otherwise direct adjustment at the BC10), we
recommend the “Aut” setting in conjunction with other boilers.
Economy mode 2), DHW temperature 60 °C
If the temperature has dropped significantly, DHW is
first heated to 60 °C again. This reduces the number
of burner starts and saves energy. However, the
water may be somewhat cooler in the first few
moments.
2) The heating program (time switch) of the programming unit
remains enabled, consequently no DHW is produced during
night operation.
30 – 60 The temperature is set at the BC10 and can then no
longer be adjusted with the programming unit.2)
Aut The temperature is set at the programming unit
(e.g. RC3x).
60 °C is set as the DHW temperature if no
programming unit is connected.
Tab. 3 Settings at the “set DHW” rotary selector
The LED below the rotary selector illuminates
whilst the DHW in the DHW cylinder is being
heated to the preselected set temperature.
Status Explanation
ON Burner operational. Boiler water is heated.
OFF Burner off. The boiler water has reached the
required temperature level or
there is no heat demand.

3.6 Resetting faults
You can reset a fault by pressing “Reset” if the burner
(combustion controller) is in a fault state. This is only
required for locking errors. Blocking errors are reset
automatically when their cause is removed.
BTo reset the error, press “Reset”.
The display shows rE whilst the system is being reset.
Fig. 6 “Reset” button
3.7 Selecting manual mode
In manual mode, the heating system can be operated
independently of a programming unit. The boiler will
operate with the boiler water temperature selected on the
r.h. rotary selector as the set temperature.
In manual mode, the decimal point on the display flashes.
BHold down d(“Chimney Sweep”) for at least
8 seconds until the decimal point flashes in the
display.
BTurn the r.h. rotary selector to select the set boiler
water temperature (boiler flow temperature).
BTo terminate manual mode, press dagain.
Fig. 7 Selecting manual mode
Floorstanding boilers:
If the fault cannot be reset, either the boiler
water temperature is still too high or the
digital SAFe combustion controller must be
reset first.
If the burner fault recurs after the reset,
contact your heating contractor.
Manual mode terminates after the power has
been switched off or if it has failed.
BAfter switching on, re-activate manual
mode so that the heating system keeps
running (especially if there is a risk of
frost).

3.8 Displaying the status
The BC10 base controller display indicates the status of
the heating system.
In case of errors, the status display immediately indicates
the relevant fault or warning. If a error occurs, contact your
heating contractor and advise them of the service and
fault codes.
The warnings and errors depend on the boiler used. For
further information on the codes please refer to the
description of the boiler concerned. Locking errors cause
the status display to flash.
Initial status:
In the standard operating state, the current boiler water
temperature is displayed, e.g. 60 °C.
BIf the display indicates a fault or warning, e.g. H7 or 2E
(ÆChapter 4.6).
Further status displays:
BTo change to the next status display, press e(“status
display”).
P1.2: Current operating pressure (subject to boiler
type only if a pressure sensor is installed).
BTo change to the next status display, press eagain.
0Y: Operating status (display code).
BTo change to the next status display, press eagain.
60: The boiler water temperature is displayed again.
