During the first heating season, begin by turning the dial setting knob to position 5, which is within the recommended operating range. This starting point allows the system to begin providing humidity. Observe your home’s condition and consult the provided figure in the manual for more detailed adjustments. This initial setting is a baseline that may require further calibration based on the humidity levels you experience.
