10.1.5.8 ACTUATOR
TEMPARATUERE ACTUATOR
The temperature actuator is a high-torque, bi-
directional with position feedback actuator is used to
control the position of Temperature motor flap via the
Temperature control voltage. The outputs are fully
compatible with all physical aspects of directly driv-
ing a motor such as the occurrence of transients at
motor turn-off due to back EMF. The temperature
control will be functional throughout the Ignition is
ON.
The Temperature Control Rotary Knob (Ring) allows
the user to mix the Hot and Cold air, to select the
various combinations by rotating clockwise. Temper-
ature knob controls the servomotor. Total Rotation
Span is 270° with 31 positions (30 detents) each of
9°. The Position of the Temperature actuator is
based on the Knob position of the Control Panel dur-
ing the Ignition ON / OFF.
