The Honeywell ML7999A2001 Universal Direct Coupled Actuator provides 100 lb-in. torque, pulse-width-modulating (PWM) control of combustion air dampers, butterfly gas valves, oil modulation valves, and flue gas recirculation systems.
The Honeywell R7999 ControLinks controller simultaneously controls the relationship between fuel, airflow and flue gas recirculation on a power burner to gain accurate control and greatly improved efficiency. The system consists of the R7999 ControLinks Controller, Q7999 Universal Subbase, ZM7999 commissioning software and up to 4 actuators.
Provides terminals for field wiring for the R7999A ControLinks™ Fuel Air Controller. Terminals on the R7999A,B Controller engage the Q7999 contacts to make electrical connections. The Q7999A Subbase is panel-mounted.
The ZM7999 Software Configuration Tool reduces burner setup time by letting you create a burner modulation curve (profile) for the burner that allows for safe and efficient operation at all points along the modulation curve.
