Proportional Integral Dervative/ PID control
PID controller is activated by temperature-sensitive thermocouple or thermopile.
Use the PID to control any other circuit.
Best to use PID to control a contactor or relay instead of directly connecting load to PID
Use contactor or relay as shown in illustrations below
''Output actuator has a resolution of about 3%''.
So if temp setting on PID is 140° then actual temperature is 140° ±3% or 4.2° margin of error.
Using a separate contactor or relay that is rated for elements and motors allows millions operations without risk of overload and burnout of PID terminals.
