Abstract (en)
[origin: EP0698767A1] The circuit has the combustion air fan (FA) connected in series with a first diode (D04) and the rest contact (PNC) of the flow switch (PS) to an a.c. current supply (L,N). This series circuit is connected in parallel with a second series circuit contg. a charging capacitor (C05) and a first resistance (R05). The stimulation winding of a relay (RY02) is connected in series with an electronic switch (Q02), this series circuit being in parallel with the charging capacitor. The control electrode of the electronic switch (Q02) receives a signal dependent on the capacitor's (C05) charge state.
