Honeywell ControLink R7999 Fuel Air Ratio Controller
The R7999 ControLinks. Controller uses the latest microprocessor-based technology to simultaneously control up to four actuators. The device, when used with the ML7999 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 R7999 ControLinks. Controller, Q7999 Universal Subbase and ZM7999 commissioning software. The R7999, with one communications port, provides communications capabilities similar to those found in the 7800 SERIES controls.
