6.10 Switching on the boiler at the BC10

B Set the rotary selector for "maximum boiler
temperature" and the rotary selector for "set DHW
temperature" to 0.
This ensures that the burner will not start yet (there is
no heat demand).
B Set the ON/OFF switch on the base controller to
position "1".
The entire heating system is switched on. During
commissioning, "-" briefly flashes on the display, then
fault message "4A"-"700" is displayed. Fault display
"4A"-"700" appears, as the burner is supplied in a fault
state.
Logano plus GB312 - Subject to technical modifications.
B Wait approx. 1 minute to enable the EMS connection
to the RC35 programming unit (available separately) to
be established.

B Press "Reset" on the BC10. The status display on the
BC10 illuminates and the display shows the current
boiler water temperature in °C.
If fault message "A11" appears, set the date and time on
the RC35 programming unit. Only then will the current
boiler water temperature be displayed.
Before continuing with further commissioning steps, set
the correct parameters on the RC35 programming unit.
The DHW heating configuration (heating circuit pump
and cylinder primary pump) must be set correctly to
ensure the heating system works properly. For this,
observe the installation and maintenance instructions of
the RC35 programming unit.
When using the Logamatic 4000 control
