Unique and cost effective solutions for improved control of combustion with greater accuracy.

R7999

R7999

The R7999 ControLinks™ controls ML7999 Actuators to controls Fuel and Air supply to a burner to maintain optimum combustion throughout its firing rate curve.

Q7999

Q7999

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.

ML7999A

ML7999A

ML7294 Non-Spring Return Direct Coupled Actuators control dampers or valves in HVAC applications. The ML7294 Non-Spring Return DCA accepts a current or voltage signal from an electronic controller to position a damper or valve.

ML7999B

ML7999B

Honeywell ML7999B universal direct coupled actuator provides 100 lb-in. torque, 4 to 20 mA control input to control combustion air dampers and modulation valves. Includes precision drive shaft control and integral power supply.

ZM7999

ZM7999

"The ZM7999 Software Configuration Tool reduces burner setup time by letting you create an R7999 Controlinks burner modulation curve. The software assists you through the commissioning process and when it's complete, you can monitor the system real-time. "
