Engineering

The electric motor, cold compressor, capacitor with fan and liquid container are built into the base cabinet. The air distribution housing with air intake shaft, fan motor, servo motors for the operation of the flaps, sensors and evaporator units are installed on the base cabinet.

The original components or the corresponding potentiometers, switches, LED's and digital display devices are mounted in clear view on the aluminium board / front panel or represented by a screen print and labeled. All control device PINs are connected in parallel to 4 mm test sockets and led through the front panel. They are logically arranged with ECU pin description according to component.

The coolant circuit is also schematically represented on the front panel. The air conditioning is switched on via the ignition switch. The individual operating conditions are adjusted or read from the control device with operating and display unit. The pressures and temperatures in the capacitor and evaporator are displayed on digital measuring devices. The various air outlet temperatures (left, right) on the air outlet nozzles can be achieved via an electronic heating element. The air outlet temperatures on the air distribution housing are displayed on digital measuring devices. The maintenance connections are original and, therefore, available for the filling station.
