Faceplate LCD Screen
The control has a 16-character LCD screen that cycles through the list of real-time data,
operating information, logged data, and setpoints. Other operating information, such as a
temperature sensor error or a manual operation delay, are also displayed. When the LCD
screen is cycling automatically, only setpoints for the presently active control strategy are
shown. If the setpoints are scrolled with a faceplate command, the LCD screen shows all
available setpoints. Table 1 on page 7 lists the real-time data, operating information, and
logged data that appears on the LCD screen.
Note:
Because of rounding differences, the IntelliLink software screens and the LCD screen
may display slightly different values for the real-time data and setpoints.
