Controller Description
Premium HMI Control Panel
The Premium Truck HMI (Human/Machine
Interface) Control Panel is available as an option
on SR-3 Truck applications. It is used to operate
the unit, display unit information and access all
SR-3 Maintenance and Guarded Access Menus.
The Premium HMI Control Panel communicates
with the base controller via the CAN (Controller
Area Network) bus. It is connected to the base
controller via CAN Connector J14 on the interface
board. The Premium HMI Control Panel is
typically located in the vehicle driver's
compartment. It may be installed in the truck
instrument panel using a DIN mounting ring or
under the instrument panel using an under dash
mounting kit.
Figure 40: Premium HMI Control Panel
The HMI control panel consists of a display and 8
touch-sensitive keys.
The display is capable of showing both text and
graphics.
The keys on the left and right sides of the display
are dedicated single function “hard” keys.
The four keys under the display are “soft” keys.
The functions of these soft keys change depending
on the operation being performed. If a soft key is
active the current key function is shown in the
display directly above the key.

Display
The display presents information to the operator.
This information includes setpoint and
temperature, unit operating information, gauge
readings, temperatures and other information as
selected by the operator.
The Standard Display of box temperature and
setpoint is shown here. The CYCLE-SENTRY
Icon in the upper right of the display shows the
unit is running in CYCLE-SENTRY (Start-Stop)
Mode. The unit has a setpoint of 35 F, and an
actual box temperature of 35.8 F. The
down-pointing arrow at the left side of the display
shows the unit is cooling.
The four keys under the display are termed “soft”
keys. The functions of these keys change
depending on the operation being performed. The
function of each soft key is shown by labels in the
display located directly above each soft key. In the
example shown above, pressing the left soft key
accesses the SETPOINT Menu and pressing the
right soft key accesses the MAIN Menu. The
other two soft keys access the GAUGES menu
and SENSORS menu as shown by the labels
above the keys.
