What it is

The Honeywell S4565BF1039B is an automatic controller used in oil-fired boiler control systems. It forms part of the burner control arrangement on the appliance, handling the automatic control function for which the S4565 range is designed. It is supplied as a service component for oil boiler applications.

Before you order

  • Confirm the part number on the existing controller matches S4565BF1039B exactly, including the suffix, before ordering.
  • Check the appliance or burner documentation to confirm the S4565 variant is the correct controller for the unit.
  • Inspect the existing controller's connections and mounting arrangement so the replacement can be fitted the same way.
