Outside Temperature Display Sensor: Description and Operation
Operation
OPERATION
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the A/C-heater control. The resistance in
the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the A/C-heater control. Based upon the resistance in
the sensor, the A/C-heater control senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific
temperature.
