Making the heating system ready for operation

▶ Turn on the fuel supply on the main fuel container and downstream of
the gas valve.
▶ Switch on the heating system emergency stop switch (if present) and/
or the appropriate circuit-breaker.
7.8 Commissioning the control unit and burner without
programming unit RC35
Follow the instruction manual for the BC10.
Refer to the AM10 Application Manual for GB312 start-up instructions.
If the boiler is not being used with an RC35 programming unit, it can be
commissioned using a PC running the Logamatic Eco-Soft 400/EMS
software and a Service Key.
Please contact Buderus for more detailed information.

Starting up the controls and the burner with RC35

programming unit

7.9.1 Boiler intended to be used with Logamatic 4000

If the boiler is subsequently to be run in conjunction with a
Logamatic 4000 programming unit, the following operations must be
carried out:
▶ Switch off the Logamatic 4000 programming unit.
▶ Use the RC35 programming unit.
▶ Continue commissioning procedure as described in Section 7.9.3.

7.9.2 Boiler intended to be used with RC35

▶ Use the RC35 programming unit.

7.9.3 Continuing commissioning procedure with RC35

▶ Turn the "maximum boiler temperature" control knob and "hot water
temperature" control knob to 0.
This ensures that the boiler does not start up at this point (no demand
for heat).
▶ Set the ON/OFF switch on the basic control unit to position "1".
This turns on the entire heating system. When first commissioned, the
display briefly shows a flashing "-" before showing fault message "4A"-
"700". The fault message "4A"-"700" is displayed because the burner
is at fault setting when delivered.
▶ Wait about 1 minute while the EMS connection to the RC35
programming unit (available separately) is established.
▶ Press the "Reset" button on the BC10. The status display on the BC10
lights up and the current boiler temperature in °F is shown.
If fault message "A11" appears, you must set the date and time on the
RC35 programming unit. Only then will the current boiler water
7 747 010 720-56.1RS
temperature be displayed.

Before continuing the commissioning procedure, set the correct
parameters on the RC35 programming unit. In particular the DHW
configuration (central heating pump and cylinder charging pump) must
be adjusted correctly to ensure the heating system works properly.
Refer to the installation and servicing instructions for the RC35
programming unit for information on how to do so.
