Temperature Control Motor

The Temperature control Motor is also powered from the BRN (141) wire cavity 10. Rotation of the Temperature control Motor moves a wiper contact along the resistance body and thus varies the voltage that is passed through the LT BLU (733) wire to the temperature control Motor. The Temperature Control Motor senses the voltage provided at LT BLU(733) cavity and commands the Motor to rotate proportionally to that voltage, i.e. full voltage is full rotation in one direction and 0 Volts is full rotation in the other.
