1 PV/SV display (red): Indicates the input value and setting value. During setting mode, characters and
setting value of the setting item are indicated in turn.
2 MEMO/STEP display (green): Indicates memory number during fixed value control. Indicates step number
during program control.
3 PV indicator (red): Lights up when the input value (PV) is indicated.
4 SV indicator (green): Lights up when the main setting value (SV) is indicated.
5 AT indicator (yellow): Flashes during AT (auto-tuning).
6 T/R indicator (yellow): Flashes during serial communication (lit while sending data, unlit while receiving
data).
7 OUT indicator (green): Lights up when control output or OUT1 (heating side, option heating/cooling
control) is ON: For DC current output type, it flashes corresponding to the
manipulated variable in a 0.25 second cycle.
8 EV1 indicator (red): Lights up when event output 1 or OUT2 (cooling side, option heating/cooling
control) is ON.
9 EV2 indicator (red): Lights up when event output 2 is ON.
10 Increase key (
△
): Increases the numeric value.
11 Decrease key (
▽
): Decreases the numeric value.
12 Mode key (
