33. Manual temperature adjustment<strong>Circuit</strong>Part 3.gif

It consists of single-junction transistor VT and resistor R. ~Rs, potentiometer RP and capacitor Cz form
a relaxation oscillator (trigger circuit). By adjusting RP, the conduction angle of the thyristor
V can be changed, thereby achieving the purpose of temperature regulation.     In the figure, the resistor Ri and the capacitor cl are the protection circuit of the thyristor .
