PID controller set comes with digital PID REX-C100 temperature controller + max.40A SSR + K Thermocouple for your use. This PID temp control is specially designed for one phase solid state relay. Proportional Band (P): 0full range (ON/OFF control when set to 0). Integral time (I): 03600 sec (no integral action when set to 0), derivative time (D): 03600 sec (no derivative action when set to 0). Setting value (SV) is identical to measuring range (PV).
