Heat exchanger temperature sensor, function - GF83.57-P-2101-01I

Function 

The heat exchanger temperature sensors are temperature dependent resistors. The resistance values measured are transferred to the automatic A/C pushbutton control module. Here the values measured (actual values) are compared with the temperatures set on the automatic A/C pushbutton control module (left and right separately). From the comparison between the actual values and set values the automatic A/C pushbutton control module calculates the opening time for the duovalves and actuates them separately for the left and right side.
