INTERNATIONAL CHILLER VISUAL CONTROLLER
(ICVC) — The ICVC is the “brain” of the PIC III system. This
module contains all the operating software needed to control
the chiller. The ICVC is mounted to the control panel (Fig. 10)
and is the input center for all local chiller set points, schedules,
configurable functions, and options. The ICVC has a stop
button, an alarm light, four buttons for logic inputs, and a
backlight display. The backlight will automatically turn off
after 15 minutes of non-use. The functions of the four buttons
or “softkeys” are menu driven and are shown on the display
directly above the softkeys.
The viewing angle of the ICVC can be adjusted for opti-
mum viewing. Remove the 2 bolts connecting the control panel
to the brackets attached to the cooler. Place them in one of the
holes to pivot the control panel forward to backward to change
the viewing angle. To change the contrast of the display, access
the adjustment on the back of the ICVC. See Fig. 10.
The ICVC features 4 factory programmed languages:
English (default)
Chinese
Japanese
Korean
NOTE: Pressing any one of the four softkey buttons will acti-
vate the backlight display without implementing a softkey
function.
The ICVC may be identified by viewing the back of the plate
on which the display is mounted. (Open the control panel door
to view.) Note any of the following distinguishing features in
Table 2.
