Control device, and associated heating and/or ventilation and/or air conditioning installation, motor vehicle and temperature management method

A control device for a heating, ventilation, or air-conditioning installation of a motor vehicle comprising an interior, said installation comprising an air treatment housing comprising:

• at least two air outlets configured to open into a zone of the vehicle interior, including at least a first air outlet positioned at a top region of the interior of the motor vehicle and at least one second air outlet at a bottom region of the interior of the motor vehicle, wherein the bottom region is at foot level,
• at least one first mixing member corresponding to the first air outlet and at least one second mixing member corresponding to the second air outlet, wherein the first mixing member is configured to mix an inlet air flow to produce a first air flow at an adjusted temperature bound for the first air outlet and the second mixing member is configured to mix the inlet air flow to produce a second air flow at an adjusted temperature bound for the second air outlet, wherein the adjusted temperature of the first air flow is different than the adjusted temperature of the second air flow,
• a user interface configured to be arranged in the vehicle interior, comprising at least one first control member for setting the adjusted temperature of the first air flow bound for the first air outlet and at least one second control member for setting the adjusted temperature of the second air flow bound for the second air outlet, and
• a control circuit configured to:
• receive, from each control member, an input signal with an individual temperature setpoint, and
• output separate control signals for controlling the first mixing member and the second mixing member, so as to independently adjust the temperature of the first air flow bound for the first air outlet and the second air flow bound for the second air outlet.
