The cooling action switches on when The cooling action the process temperature rises above switches the set point plus the hysteresis on at startup Hysteresi Process Temperature ysteresis Set Point Temperature The cooling action switches off when the process temperature drops below the set point Time Proportional Control Some processes need to maintain a temperature or process value closer to the set point than on off control can provide Proportional control provides closer control by adjusting the output when the temperature or process value is within a proportional band When the value is in the band the controller adjusts the output based on how close the process value is to the set point The closer the process value is to the set point the lower the output power This is similar to backing off on the gas pedal of a car as you approach a stop sign It keeps the temperature or process value from swing ing as widely as it would with simple on off control However when the system settles down the temperature or process value tends to droop short of the set point With proportional control the output power level equals set point minus process value divided by the proportional band value Set Point P iui In an application with one output assigned to heating and another assigned to cooling each will have a separate proportional parameter The heating param ter takes effect w
