A motor-actuated actuated-vent-valve is configured to operatively couple to a vent port of a solid-fueled cooker. The vent port is in series with both a flow of air into a combustion region of the cooker, and a flow of resulting combustion gases from the cooker, the flow of air being responsive to a position of the actuated-vent-valve. A first controller adapted to receive a sensed-temperature signal responsive to a temperature within a cooking region of the cooker, and operatively coupled to an externally-located actuator motor of the motor-actuated actuated-vent-valve, provides for automatically electronically controlling the position of the actuated-vent-valve to a continuum of positions within a range of the positions, thereby substantially regulating the first temperature within the cooking region of the solid-fueled cooker to a user-defined temperature level responsive to the sensed-temperature signal by controlling an exclusively-naturally-occurring flow of air into the combustion region of the cooker.
