R7999A1013/U
F/A Ratio Control – Cleaver Brooks
This product is available in the US only.
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, airflow and flue gas recirculation (if used) on a power burner.
The Control inks 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.
