50hz pid leak rate pdf

If the value of register 85 is 0, 16384 or 32768, your controller's PID loop type is already set to PD/PDF. If the value of register 85 is 2, 16386 or 32770, your controller's PID loop type is set to PD 2 I. Subtract 2 from this value, and then type aw85=[new value]<CR. Set all PID variables. Record your controller's existing PID settings.
