The Nibe Large Grey On/Off Knob (Part Number: 518660) is a genuine replacement control knob used on the front panel display assemblies of legacy Nibe Fighter series heat pumps, boilers, and indoor modules.

Unlike the smaller offset/navigation knob (518659) used for menu scrolling, this larger diameter knob is primary-function hardware, typically serving as the power/mode selection or main dial on the controller fascia.
