The "On-Off Primary Burner Control" from Honeywell is designed with an intermittent pilot type, making it suitable for power requirements of 120 VAC at a standard frequency of 50/60 Hz. This unit operates with an intermittent main flame establishing period and offers a choice in pilot flame establishing period, selectable between 4 and 10 seconds.

The On-Off Burner Control ensures comprehensive functionality, automatically orchestrating burner sequencing and providing optimal flame supervision. For added convenience, it showcases system status and conducts system or self-diagnostics for efficient troubleshooting.

Please note, a subbase and amplifier are required to operate this Honeywell device. Additional options such as a Modbus interface, keyboard display module, or remote display module can be integrated to enhance system compatibility and control. Five built-in LEDs provide clear sequence information, and the plug-in amplifiers are fully interchangeable.

The Burner Control also allows for local or remote annunciation of operational and fault information, granting users the option to receive critical system updates remotely. After a power outage, the unit's non-volatile memory retains all history files and lockout status information, ensuring no data loss. Users can also select the relight or lockout option in case of flame loss.

This model functions optimally in harsh environments and can withstand operating temperatures ranging from -40 F to 140 F. It markets the essential capabilities of an "On-Off Primary Control" in the field of industrial automation and control systems.
