CIRCUIT OPERATION
TEMPERATURE CONTROL
The Air Temperature Valve Sensor positions the temperature door according to the temperature setting of the temperature control on the temperature
control /mob. For the full cold temperature setting, the temperature control returns approximately 1.0 Volt to the Air Temperature Valve Sensor. When
the temperature setting is changed to full HOT, the temperature door is moved to the warm position, and the output rises to about 12 Volts. For a
temperature setting in the mid range, the temperature door positions itself according to the voltage supplied through the temperature control switch.
Should the motor stall when changing the door location, voltage is removed by the Heater Controller / Heater and A/C Controller after 45 seconds to
protect the motor.
