Climate Control Options

The climate control panel allows you to control the heating, ventilating, defrosting, and air conditioning functions. Western Star vehicles have several heater and air conditioner options.

Options for the cab include:

• heater and air conditioner

• heater and air conditioner with automatic temperature control (ATC)

Options for a sleeper unit include:

• no heater or air conditioner

• heater only

• heater and air conditioner

• heater and air conditioner with ATC

The ATC feature automatically controls the heating and cooling system to maintain the cab and sleeper air temperature close to the temperature set by the user. The ATC adjusts the air temperature blown through the air outlets to maintain the selected temperature.
