Tune and Operate Tuning Automatic Auto tuning The THERMO DUCER CSM4 can automatically tune the PID parameters to fit the characteristics of your particular thermal system The auto tuning procedure operates on a thermal response value slow medium or fast Use the slow thermal response when your process does not need to reach set point too rapidly or if it usually does not exceed set point a lot A fast thermal response produces a rapid temperature change over a short period of time Once the auto tune sequence has begun the heat proportional band will be set to 0 and the control goes into an ON OFF mode of control at 90 of the established set point The displayed set point remains unchanged The cool output remains off for the duration of the tuning Once the control finishes learning the system it returns to a standard PID control with the heat PID values automatically set as a result of the auto tuning Tuning is complete within 80 minutes Any change of the set point while in auto tune re initiates the auto tune procedure The THERMO DUCER will not Auto tune while in remote set point Transferring from local to remote set point takes the CSM4 out of Auto tune and may bump to the new set point determined by the input voltage Remote to local is bumpless To start auto tuning 1 Press the MODE key until the AUt prompt appears in the data display 2 Selecta thermal response value 1 slow 2 medium a
