1. Manual method: First, to pull combination switch HK to manual position, then the contacts of KK1 are connected, the relay J coil is energized pull, the AC contactor IC takes action, resistance furnaceis heating, when the temperature rose to the required temperature, to pull KK to 0 position, so that J and JC coil lose power, electrical furnace loses the power, and it won's rise the temperature again. 2. Automatic way: To pull combination switch HK to the automatic position, then the contacts of KK2 are connected, since the digital potentiometer thermometer CB is below the predetermined temperature, contact CB is closed, so that J is energized pull, and IC coils get electric power to heat up the electrical furnace. When the temperature reaches a predetermined temperature, contact CB automatic breaking, so that J coil and IC breaking, electrical furnace stops heating, to realize automatic temperature control. The K in the chart is the power switch of meter. HD and LD are the energizing and breaking indications.
