- **learning_time_offset_hours** (*Optional*): Time constant to estimate the NOx algorithm offset from the history in hours. Past events will be forgotten after about twice the learning time. Allowed values are in range 1..1000. The default value is 12 hour

- **std_initial** (*Optional*): The initial estimate for standard deviation parameter has no impact for NOx. This parameter is still in place for consistency reasons with the VOC tuning parameters command. This parameter must always be set to 50.

- **gain_factor** (*Optional*): Gain factor to amplify or to attenuate the VOC index output. Allowed values are in range 1..1000. The default value is 230.
