Temperature Rotary Knob

When the temperature rotary knob is in the full COLD or counter clockwise position, all of the air delivered by the ventilation system is unheated. When the temperature rotary control is in the full HOT or clockwise position, all of the air passing through the heater module is heated prior to discharge. Intermediate positions of the temperature rotary knob result in a mixture of heated and unheated air in order to provide more moderated air temperatures.
