Some computerized automatic temperature controls have a defroster nozzle to deal with fog on windows and windscreen.

Major components

The main components of automatic temperature control are:

Sensors

Sensor supply input data to the controller. Some examples of sensors include sun load sensor, outside temperature sensors, coolant temperature sensor, vehicle speed sensor and in-car temperature sensor.

Control panel

A control panel is located in the instrument panel at a convenient place to allow the driver and passengers to input controls to the temperature control system. Usually, the control head has microprocessors to provide input data to the operator depending selected conditions.

Output device

Puts signal from sensors into action. They include electric motors and vacuum solenoid

Controller

It is the brain behind the computerized automatic temperature control. A controller is also known as a programmer. It provides output signals to determine blower speed and close or open heat water valve among other functions.

Other common devices include power modules, clutch diode, low pressure switch, aspirator and water valve actuator.

Computerized ATC system contains other components such as duct work, blower motor and refrigeration system.

The controller processes data from sensors and then issues output commands to various devices. It keeps the temperature of the vehicle stable according to the choice of occupants. In essence, they are mini computers or microprocessor devices. After gathering signals, the end result is some kind of mechanical motion. For instance, it can control the opening and closing of the heater control valve. Computerized ATC does not only result in motion; sometimes it issues electrical commands to other components of the system.

An advanced system may offer a dual-zone climate control which incorporates a recirculation mode. Automatic temperature control also measures the quality of air in the car’s cabin through various sensors. It maintains the temperature depending on sunlight and air intake quality through coded settings.

Different manufacturers use different names to brand their computerized air temperature control. For example, Mercedes Benz uses THERMOTRONIC term for their cars ATC systems. High end cars take computerized automatic temperature control a notch higher. It allows drivers and front passengers to set temperatures in their areas independently. This is a dual zone system. Tri-zone and quad-zone allow passengers in the back seat to control temperatures in their area. Passengers in the rear seat get better quality air by using recirculation and rear ventilation option.

Ultra-luxury cars feature state of the art automatic air control systems. For instance, some have a rear cabin air conditioning with front and rear controls for speed and temperature. Newer car models come with a touch screen panel using an automatic air conditioner.
