R7999C 
ControLinks™ Controller

APPLICATION

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.

The R7999C, with one communications port, provides 
communications capabilities similar to those found in the 
7800 SERIES controls.

FEATURES

• 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:

—

Water temperature low fire hold.

—

Stack temperature low fire hold.

—

FGR and low fire hold.

• 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.

• Six light-emitting diodes (LED) provide:

—

System  status.

—

Fault information.

—

Status of four actuator channels.
