Fig. 3 Setting the control unit
▶ Set the ON/OFF switch on the basic control unit to position "1".
The control unit checks the current status of the system, and the
burner may start up.
When the boiler detects a demand for heat, the startup sequence begins
and the burner ignites after about 30 seconds. Heat demand arises
when the central heating or DHW temperature falls below the set
temperature. The LED below the relevant control knob lights up.

Turning the heating system off

Turn off the heating system on the Logamatic BC10 basic control unit.
When the Logamatic BC10 basic control unit is switched off, the burner
is automatically shut down at the same time.
▶ Switch off the heating system at the BC10 ON/OFF switch (position
"0"). This switches off the boiler and all its components (such as the
burner).
▶ Turn off the main isolating valve.
CAUTION: Risk of system damage due to freezing.
If the heating system has been switched off, it may
freeze up at sub-zero temperatures.
▶ Leave the heating system permanently switched on as
much as possible.
▶ Protect your heating system against freezing by
draining the heating system and hot water pipes at the
lowest possible point.
