The R7999C ControLinks™ Controller uses the latest microprocessor-based technology to simultaneously control up to four actuators. The device, with the ML7999C Universal Parallel Positioning Actuators, represents a value-added replacement of mechanical cam and linkage assembly controlling the relationship between fuel, airflow and flue gas recirculation (if used) on a power burner. The Honeywell ControLinks™ System consists of the R7999C ControLinks™ Controller, Q7999 Universal Subbase and a minimum of two ML7999C Actuators.


  • Fast burner setup via PC, laptop, or S7999 touchscreen display.
  • Fuel, air, FGR profile download capability.
  • Two independent fuel profiles with or without FGR.
  • 7 to 24 point profiles.
  • Programmable behaviors of all actuators during Purge and Standby.
  • Programmable behavior of nonselected fuel actuator.
  • Independent lightoff and minimum modulation positions.
  • Wide power voltage input range (50/60 Hz); two models cover global applications.
  • Auto/Manual input.
  • Manual mode firing rate input
  • Pluggable controller to wiring subbase.
  • Multipurpose communications port.
  • Field-configurable device.
  • Integrated boiler shock protection algorithms
  • Selectable FGR hold based on stack temperature.
  • Programmable behavior of FGR actuator during purge.
  • Maximum modulation limit capability.
  • Remote reset input.
  • Automated actuator endpoint seeking process.
  • UL, CSD-1 and NFPA acceptable.
  • Negative/flatline FGR.
  • Nonvolatile memory stores operating history and current lockout and alarm status.
