Heat/Cool Man Reset

Enter a value to add to the PID output calculation. When the
corresponding Integral is set to zero, the value substitutes for
the integral sum portion of the feedback calculation. In this
case, the output equals the heat/cool manual reset value when
the process variable is at set point. When the integral value is
set to a value other than zero, the manual reset value is added
to the result of the PID calculation and, thereby, shifts the
output variable.

Range: 0.0% to 100.0%

Heat/Cool Output Dest

Select the output destination to specify the I/O point used for
the control output. This is the output for the closed-loop control
channel. Selecting Not Assigned indicates no output is to be used,
and is an appropriate setting for monitor-only channels.

If both heat and cool output destinations are set, the channel
performs bimodal control. See Heat and Cool Outputs on page
90
for more information on this type of control.

Range: Any output found on the Dig I/O or Outputs spreadsheet
or any of the Soft Bool or Soft Int registers.

Heat/Cool Output Type

This field specifies the type of output signal and determines
whether the PID or on/off control algorithm is used for the
channel. Refer to AnaWin3 Output Types on page 120 for a
description of the output type options.
