Front Panel Layout

Front Panel Display & Indicators

The front panel features a Process Value Display showing numerical readings (e.g., '15.0', '18.0'). It also includes indicators for Alarm-1, Alarm-2, and HOLD status.

Control Keys

The control keys are: PROGRAM (PRG), UP (▲), and DOWN (▼).

Keys Operation

Symbol	Key	Function
PRG	PROGRAM MODE	Keep pressed for approximately 5 seconds to enter / exit Set-up mode.
▼	DOWN	Press to decrease the parameter value. Pressing once decreases the value by one count; holding pressed speeds up the change.
▲	UP	Press to increase the parameter value. Pressing once increases the value by one count; holding pressed speeds up the change.
