Dead Band: Enter the Dead Band between the heating and cooling functions
adjustable from ± 99°F/± 55°C. The default is 0°. Appears when Ot2 = CL.
Alarm Low: Represents the low process alarm or low deviation alarm.
Displayed only when 0t2 parameter is AL.
Alarm High: Represents the high process alarm or high deviation
alarm. Displayed only when Ot2 parameter is AL.
Calibration Offset. The range is ±99°F/±55°C. The default is 0°.
Calibration Offset adds or subtracts degrees from the input signal.
Auto-Tune. The range of this parameter is 0-3, off = 0, slow = 1,
medium = 2, and fast = 3. A value other than 0 initiates the auto-tune.
Local-Remote: Selects a local or remote set point for the Series 980/985.
Local set point is adjustable directly from the 980/985, while remote can only
be changed from an external device. The signal must be within O-5V or 4-
20mA process input. This parameter appears if the LOC parameter = 0, 1 or 2,
and
rSP = 0-5 or 420. If L-r = the remote set point is displayed in place of the
internal set point.
