Technical Explanation for Temperature Controllers
www.ia.omron.comoperation is also called two-position control action. P action (or proportional control action) is used to output a manipulated variable (control output variable) that is proportional to the deviation in order to decrease the deviation between the process value and set point. A proportional band
