Honeywell ControLinks R7999 Series Actuator Controls

Controls ML7999 Actuators supplying Fuel and Air to a burner maintaining optimum combustion throughout its firing rate curve

Uses microprocessor-based technology to control the ML7999 Universal Parallel Positioning Actuators. This represents a value added replacement of mechanical cam and linkage assembly controlling the relationship between fuel, air flow and flue gas recirculation (if used) on a power burner. The ControLinks Fuel Air Control System consists of the R7999 Fuel Air Controller, Q7999 Wiring Subbase, ML7999 Universal Parallel Positioning Actuator and ZM7999 Configuration Software. The R7999, with one communications port, provides communications capabilities similar to those found in the 7800 SERIES controls.
