The RKW's built-in temperature control lets it respond to that change directly, stepping up airflow as heat builds without any manual adjustment.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cp\u003eWire the fan directly to mains power — the built-in temperature control handles speed adjustment automatically as room conditions change. Mount with the airflow arrow pointing away from the room, and keep the intake grille clear of dust to avoid tripping the thermal cut-out.
