A landfill gas well control system for use with a wellhead assembly to control a flow of landfill gas from a landfill well, the system comprising: a landfill gas wellhead flow control valve operably associated with the wellhead assembly; a flow control actuator operably associated with the wellhead assembly for controlling movement of the LFG flow control valve; a sensor operably associated with the wellhead assembly for sensing a flow related variable associated with the landfill gas; a combination unit including a housing and being secured to the wellhead assembly to be supported by the wellhead assembly above a ground surface to enable visual access by an individual, the combination unit including: a controller housed within the housing and operably associated with the flow control actuator and the sensor for controlling the flow of the landfill gas through the wellhead assembly; a user interface present on the housing and including a set selection for enabling a set point associated with the flow related variable, which is to be controlled by the system, to be input to the system by a user; a non-volatile memory housed in the housing and in communication with the controller for storing LFG flow related data collected during operation of the wellhead assembly, wherein the controller thereafter operates to control the LFG flow control valve as needed, using the stored flow related data, to maintain the set point in an autopilot-like fashion. a landfill gas wellhead flow control valve operably associated with the wellhead assembly; a flow control actuator operably associated with the wellhead assembly for controlling movement of the LFG flow control valve; a sensor operably associated with the wellhead assembly for sensing a flow related variable associated with the landfill gas; a combination unit including a housing and being secured to the wellhead assembly to be supported by the wellhead assembly above a ground surface to enable visual access by an individual, the combination unit including: a controller housed within the housing and operably associated with the flow control actuator and the sensor for controlling the flow of the landfill gas through the wellhead assembly; a user interface present on the housing and including a set selection for enabling a set point associated with the flow related variable, which is to be controlled by the system, to be input to the system by a user; a non-volatile memory housed in the housing and in communication with the controller for storing LFG flow related data collected during operation of the wellhead assembly, wherein the controller thereafter operates to control the LFG flow control valve as needed, using the stored flow related data, to maintain the set point in an autopilot-like fashion. a controller housed within the housing and operably associated with the flow control actuator and the sensor for controlling the flow of the landfill gas through the wellhead assembly; a user interface present on the housing and including a set selection for enabling a set point associated with the flow related variable, which is to be controlled by the system, to be input to the system by a user; a non-volatile memory housed in the housing and in communication with the controller for storing LFG flow related data collected during operation of the wellhead assembly, wherein the controller thereafter operates to control the LFG flow control valve as needed, using the stored flow related data, to maintain the set point in an autopilot-like fashion.
