Proportional Band Coefficient. Sets the value of the
proportional band for output 2. The proportional band of
output 2 is equal to the proportional band of output 1
multiplied by the proportional band coefficient. This parameter
is only available when the control mode is set to PID and Dual
Loop Output Control.
Dead Band. The zone centered on the set point in which the
control is thought to be at the desired set level. The outputs
will be turned off at this point unless there is an integral
deviation offset or the dead band is negative. This parameter
is only shown when the control is set to Dual Loop Output
Control.

Process Temperature Offset. This feature allows the input value to
be changed to agree with an external reference or to compensate
for sensor error.
Analog Output High Limit: Sets the actual upper limit of the
analog output when the control’s output is operating at 100%.
Only available for analog output models.
Analog Output Low Limit. Sets the actual lower limit of the
analog output when the control’s output is operating at 0%.
Only available for analog output models.
Output operation of ON/OFF control during dual loop output control.
PID control Dead Band is positive.
