Figure 1 - Front panel parts

Status display/PV: shows the value of PV (Process Variable). When
in programming mode, shows the parameter name.
Parameter display/SV: shows the SV (Setpoint Variable) value and
the value of other parameters of the controller.
COM Indicator: Flashes when communication messages are sent by
the controller.

TUNE Indicator: Lights during the execution of PID automatic
tunning.

MAN Indicator: Lights when the controller is in manual.

RUN Indicator: Lights when the controller is active, with control and
alarm outputs enabled.

OUT Indicator: For relay or pulse control output, reflects the actual
state of the output. If an analog output is assigned for control, lights
continuously.
