Heat/Cool Integral
Enter the integral constant. A larger value yields less integral
action.
Values:
0 (off) to 6000 seconds per repeat
Default:
For the Heat integral parameter, 180. For the Cool
integral
parameter, 60.
DeviceNet Object:
Control (66 hex)
Heat/Cool Derivative
Enter the derivative constant. A larger value yields greater de-
rivative action.
Values:
0 to 255 seconds
Default:
0
DeviceNet Object:
Control (66 hex)
Heat/Cool Manual Reset
A process that uses only proportional control settles at a point
above or below the set point; it never reaches the set point.
This is known as offset or droop. At this parameter, enter the
power level required to maintain set point to compensate for
this offset.
Values:
0 to 100% (0 to 1000). Values in parentheses are for
communications.
Default:
0% (0)
Decimal Placement for DeviceNet:
See Decimal Placement
for Percentage Values on page 60.
DeviceNet Object:
Control (66 hex)
Heat/Cool Filter
Use this parameter to dampen the response of the heat or cool
output. The output responds to a change by going to approxi-
mately two-thirds of its final value within the specified num-
ber of scans. A larger value results in a slower response to
changes in the process variable.
Values:
0 (off) to 255
Default:
3
