Unit Control
Panel (UCP)
The main body of the screen is
used for description text, data,
setpoints, or keys (touch
sensitive areas) The
double up
arrows
cause a page by page
scroll either up or down. The
single arrow
causes a line by
line scroll to occur. At the end of
the screen, the appropriate scroll
buttons will disappear.
The bottom of the screen is the
persistent area. It is present in all
screens and performs the
following functions. The
left
circular area
is used to reduce
the contrast and viewing angle
of the display. The
right circular
area
is used to increase the
contrast and viewing angle of
the display. The contrast control
will be limited to avoid complete
“light” or complete “dark”,
which would potentially confuse
an unfamiliar user to thinking
the display was malfunctioning.
Persistent keys
, horizontal at the
bottom of the display, are those
keys that must be available for
operation regardless of the
screen currently being displayed.
These keys are critical for
machine operation. The
Auto
and Stop
keys will be presented
as radio buttons within the
persistent key display area. The
selected key will be dark. The
chiller will stop when the
Stop
key is touched, entering the stop
sequence. Pressing the
“Immediate Stop” button will
cause the chiller to stop right
away.
The AUTO and STOP, take
precedence over the ENTER and
CANCEL keys. (While a setting is
being changed, AUTO and STOP
keys are recognized even if
ENTER or CANCEL has not been
pressed. Selecting the Auto key
will enable the chiller for active
cooling.
