AUTO 0:
For special requirements, AUTO 0 can be used with manual adjustment of the control
parameters.
If the PID control (AUTO 0) option is selected, the following items including Kp 1, Ti 1 and Td 1
could be set. Otherwise they are not displayed in the menu list.
°C
t
Note: Inappropriate settings may produce the following cooling down curves:
Proportional coecient of PID (Kp 1)
Integral time of PID (Ti 1)
Differential time of PID (Td 1)
The proportional coecient Kp is the controller amplification and determines how strongly
the control deviation (the difference between the target temperature and actual temperature)
directly affects the control variable (cooling down time). Kp values that are too large can lead
to the controller overshooting.
The integral time Ti (s) is the correction time and determines how strongly the duration of the
control deviation affects the control variable. Ti compensates an existing control deviation. A
high Ti means a smaller and slower effect on the control variable. Ti values that are too small
can lead to instability of the controller.
The differential time Td (s) is the derivative time and determines how strongly the rate of
change of the control deviation affects the control variable. Td compensates for rapid control
deviations. A high Td means a smaller and slower effect on the control variable. Td values that
are too small can lead to instability of the controller.
