Operating logic

OPERATING LOGIC

A special electronic control unit manages the automatic operation of the system controlling the thermodynamic parameters to ensure a comfortable climate (temperature and humidity) for the vehicle occupants.

ECU = electronic control unit
Te = outside temperature
Ta = passenger compartment temperature
Tt = treated air temperature (at the vents)
TR = requested temperature
RIC = recirculation function
T = air temperature sent to the passenger compartment
Q = air flow rate sent to the passenger compartment

- - - - "climate control" version only
Sa = frost sensor
A/C = compressor engagement (air refrigeration circuit)

According to the requests received and the temperature conditions detected, the control unit carries out/sets certain functions aimed at adjusting the temperature of the passenger compartment to meet the requirements.
