Aspen Interface
Overview of the Aspen Interface controls and home screen
The Aspen Interface (AI) is the user control for the system. The AI turns the unit on and off and allows you to select the mode of operation.
• 1 – ON/OFF button: turns the power unit on and off • 2 – Display: shows temperatures, fan speed and menus • 3 – MENU button: opens the menu and goes back to the previous screen • 4 – Dial: changes fan speed, temperature and menu selection • 5 – Alarm light: lights when a system alarm is active
The system includes three main modules: • Climate Control Module (CCM) — Contains temperature control software and input/output circuitry to interface with unit controls. Receives high and low voltage inputs from the power unit and controls high and low voltage outputs. • Auxiliary Power Unit Module (APU) — Monitors input signals from the power unit and controls engine related outputs. • Aspen Interface (AI) — The user control that turns the unit on and off and selects the mode of operation.
The Aspen Interface has five controls: • On/Off Button — Turns the power unit on and off • Display — Shows temperatures, fan speed, and menus • Menu Button — Activates the menu screen and navigates to the previous selection screen • Dial — Changes fan speed, temperature, and menu selection • Alarm Light — Illuminates when a system alarm is active
The home screen is the default screen when the system is ON. It displays: • Cab temperature • Set temperature • Outside temperature • Current time • Fan speed indicator (shown on the left side of the screen)
