Microprocessor-based integrated burner control for industrial semi-automatically fired gas, oil, coal or combination fuel single burner applications.
Provides level of safety, functional capability and features beyond conventional controls.
Functions include purge, burner pilot startup, flame supervision, system status indication, system or self diagnosis and troubleshooting.
Delays admission of fuel to combustion chamber until pilot flame has been proven and then monitors the flame through the run period while providing system status indication.
Includes Keyboard Display Module.
Five LEDs provide sequence information.
Intermittent pilot valve.
Interchangeable plug-in flame amplifier.
Access for external electrical voltage checks.
Nonvolatile memory retains history files and lockout status after loss of power.
Selectable pilot flame establishing period.
Provides application flexibility and optional communication interface capability.
Compatible with existing Honeywell flame detectors.
