Select the input type that corresponds to the input sensor.
Select either degrees Fahrenheit or Celsius. For linear mV and ohms input
types, this has no effect. If changed, adjust related parameter values, as the
controller does not automatically convert them.

Select whole degrees, or tenths of degrees for Temperature display, Setpoint
values, and related parameters. For Linear Resistance inputs I, the same
parameter selections apply in ohms or tenths of an ohm. For mV inputs I,
only hundredths of a mV resolution is available.

This value offsets the controller’s temperature display value by the entered
amount. This is useful in applications in which the sensor cannot provide the
actual temperature signal due to mounting constraints, inaccuracy, etc.

The controller has a programmable low setpoint limit value to restrict the

USER INPUT FUNCTION (OPTIONAL)
The controller performs the selected User Input function (User Input
available only on models with alarms), when the User terminal 1 is connected
(pulled low) to Common terminal 8.
No Function: No function is performed.
Program Lock: The Configuration Loop is locked, as long as activated
(maintained action).
Integral Action Lock: The integral action of the PID computation is disabled
(frozen), as long as activated (maintained action).
Auto/Manual Select: This function selects (maintained action) Automatic
(open) or Manual Control (activated).
Setpoint 1 or 2 Select: This function selects (maintained action) Setpoint
1(open) or Setpoint 2 (activated) as the active setpoint.
Setpoint Ramp Disable: The setpoint ramping feature is disabled, as long as
activated (maintained action). Any time the user input is activated with a
ramp in process, ramping is aborted.
Reset Alarms: Active alarms are reset, as long as activated (maintained action).
Active alarms are reset until the alarm condition is cleared and triggered
again (momentary action).

DIGITAL FILTERING

= least to

= most
The filter is an adaptive digital filter that discriminates between measurement
noise and actual process changes. If the signal is varying too greatly due to
measurement noise, increase the filter value. If the fastest controller response is
needed, decrease the filter value.
