Front Panel Display During Cold Ambients
If the Display andTouch Screen Lock feature is disabled,
the following screen is automatically displayed if the
DynaViewTemperature is below freezing and has been 30
minutes after the last keystroke.
Note: This
feature is provided to avoid unintended
actuations of the keypad, which can occur due to
ice build-up on the DynaView’s exterior surfaces.
Also be aware that at extremes of temperatures,
the LCD display screen will change its contrast from
the optimal adjustment made at more normal
temperatures. It can appear washed out or blacked
out. Simply pressing the lower right contrast
control on the screen will return the display to
readable condition.
Note: All screens shown in this section are typical. Some
screens show all display options available, only
one of which may appear on a line.
Modes Screen
The Mode Screen is only found on software revisions 18
and later.This screen provides a display for the top level
operating mode for each of the components and sub-
components of the chiller (i.e. Chiller, Circuits, and
Compressors) that exist on the Chiller as it is configured.
The modes are displayed as text only without the hex
codes.

and
the sub mode for each component was displayed on
the respective component tab on the first two lines.The
mode display of the first three lines of the Compressor and
Chiller Screen tabs is eliminated with the addition of the
