Control Type
Select the function of the channel. Refer to Table 3.12. Refer to
Heat and Cool Outputs on page 90 for more on PID1 and PID2.
Table 3.12 AnaWin3 Control Types
Heat/Cool Prop Band
Set the proportional band. Larger numbers result in less
proportional action for a given error or deviation from set point.
This parameter is set in engineering units.
Range: depends on the input type. See Table 3.15 on page 130.
Heat/Cool Integral
Enter the integral term value which controls the amount of
influence the history of error has on the output. Increasing the
integral value decreases the integral contribution to the
output. Entering an integral value of 0, however, yields no
integral action. This value is in seconds per repeat.
Range: 0 to 6000 seconds/repeat
Heat/Cool Derivative
Enter the derivative term value which controls the amount of
influence the rate of change of the error has on the output. A
greater value yields a greater derivative action. The derivative
constant is in units of seconds.
Range: 0 to 255 seconds
Control Type Description
PID1
Heat and Cool outputs used to control.
Only one output may be on at a time.
PID2
Heat and Cool outputs used to control.
Both outputs can be on at the same time.
Retransmit
Choose this type to use the channel to
retransmit one or two analog inputs.
