Working principle of electronic fan regulator: Before giving the power supply keep the rheostat or potentiometer within the maximum resistance position in order that no triggering is applied to TRIAC and hence the TRIAC are going to be within the cutoff mode.

After giving the power supply varies the potentiometer slowly so that the capacitor starts charging at the time constant determined by the values of R and C.

Once the voltage across the capacitor is more than the breakover voltage of the DIAC, It starts conducting. Thus the capacitor starts discharging towards the gate terminal of TRIAC through DIAC.
