As of 2016, features of Honeywell burner controls including the RM7800 and R7140 series programmers include automatic flame supervision, burner sequencing, self-diagnostics and a system status indicator. The programmers use microprocessor technology to integrate control single-burner applications that fire automatically using gas, coal, oil or a combination of fuels. Other features include system troubleshooting, a five-function run/test switch, keyboard display module and compatibility with Honeywell flame detectors. The controls offer the capacity for communication interface and application flexibility.Continue Reading
The Honeywell RM7800 series burner controls feature external electrical voltage check access and five light-emitting diodes display sequence information. The programmer's plug-in flame amplifiers are interchangeable. In the event of a power failure, the system retains the history files and lockout status in its nonvolatile memory. Remote or local operation and fault information annunciation is an available option. Part of the RM7800 series, the CR7890 integrated burner control detects flames and offers burner safety sequencing in a compact all-in-one design.
Honeywell electromechanical relay modules are primary burner controls for commercial and industrial applications of single or dual fuel burners. The relay modules provide electronic solid-state flame safeguard protection by detecting rectified or ultraviolet signals that indicate flames. The RM7838C is an industrial-use semi-automatic integrated burner control for oil, coal or gas combustion fuel single-burner applications that fire semi-automatically. The system includes relay and keyboard display modules, amplifier, wiring sub-base and purge card.Learn more about Heating & Cooling
