HVAC Programmer
HVAC PROGRAMMER DESCRIPTION
HVAC Programmer
The HVAC programmer contains a micro-processor and is the "brain" of the electronic dual zone A/C system. The programmer receives electrical
signals from the heater and A/C control, passenger temperature control, right and left solar sensors, outside temperature sensor, inside temperature
sensor, blower control module, powertrain control module, drive and passenger air mix valve actuators. A microprocessor in the programmer processes
the signals and then sends commands to the system components which control A/C compressor clutch operation, air intake location, air discharge
location, air discharge temperature and blower speed.
