Operating Instructions
The HMI (Human Machine Interface) is typically mounted in
the bunk area of the truck cab. The operator can select the
desired function of the system. It has three selector knobs and
system condition display. The HMI contains the Cab
Temperature Sensor. It communicates with the Controller using
the Controller Area Network (CAN).

The operator can select these functions from the HMI:
•
System On/Off
•
Mode (Cool, Fan, Heat)
•
Cab Temperature (Cooler/Blue-Warmer/Red)
•
Fan Speed (Off, Low, Medium, High)
When any change of settings is made there is a two second
delay before the controller will recognize the new setting. This
prevents momentary or accidental mode changes.
The HMI indicator LEDs will dim after 90 seconds if no
selections are made. Bump the On/Off button to activate bright
display for an additional 90 seconds.
