As shown by the built-in temperature sensor  TC620 triac to control the temperature control. Adjustment circuit Rp1 and Rn, respectively, to change the lower limit temperature control point and the upper limit temperature control point, LED1 lit that the ambient temperature exceeds the lower limit temperature control point, LED2 lights to indicate that the ambient temperature exceeds the upper limit temperature control point. Triac BCR's rated operational current of the selected according to the actual charged with the size of the load power.
