Treated air temperature sensor

TREATED AIR TEMPERATURE SENSOR

This is inside the distributor unit immediately upstream of the air flow distribution ports to the different vents.

It is an NTC sensor (R at 25°C = 10 kOhm), with operating range from 0°C to +80°C.

REQUIRED TEMPERATURE POTENTIOMETER

The potentiometer is connected to the temperature knob and detects the different angular positions, thereby transmitting a signal to the electronic control unit for a total of 15 different positions (one per degree centigrade) the two extreme positions of which are "LO" and "HI".

REQUIRED AIR FLOW POTENTIOMETER

The potentiometer is connected to the air ventilation knob and detects the different angular positions, thereby transmitting a signal to the electronic control unit: there are four possible air flow rates set manually permanently (1, 2, 3 e 4), plus the "AUTO" and "0" position.

SET OF SWITCHES AND RECIRCULATION/COMPRESSOR ENGAGEMENT FUNCTION

When button (1) is pressed it engages the recirculation function managed entirely manually.

When button (2) is pressed, it enables operation of the compressor of the air conditioning system.
