Integrated Boiler Controllers
APPLICATION
These integrated boiler control modules provide ignition
sequence, flame monitoring and safety shutoff for
intermittent pilot spark ignition, or direct spark ignition
heating systems. They also provide limit rated water
temperature control with one or two sensors and display
interface capability for either "on-board" or remote user
interface applications.
• S9360A—Spark Ignition, Intermittent Pilot, Remote
Display.
• S9361A—Spark Ignition, Intermittent Pilot, "On board"
Display.
• S9380A—Direct Spark Ignition, Remote Display.
• S9381A—Direct Spark Ignition, "On board" Display.
• Enabled with EnviraCOM™ communication capability
to support remote monitoring and diagnostics.
• Limit-rated Temperature Sensing Probe.
• Ignitor sensor type
— two rod (separate ignitor and sensor)
— one rod (combined ignitor and sensor)
2012 DOE Compliance and Operation
Operation of this control may delay the burner operation while the residual heat is circulated
out of the boiler.
NOTE:
This operation may be different than earlier integrated boiler control
revisions which did not implement thermal purge.
