Viewing the humidity and carbon dioxide levels measured by the sensors

The ventilation unit’s integrated humidity and carbon dioxide sensors control ventilation automatically, as necessary. Ventilation can also be adjusted automatically by using an optional carbon dioxide, humidity, or VOC (air quality) sensor.

NOTE:

Ventilation units manufactured before 2020 have only an integrated humidity sensor.

You can view the humidity and carbon dioxide levels measured by individual sensors:

  1. Select Settings.
  2. Select Temperatures and sensors with the arrow buttons:
  3. Select OK.
    TIP:

    You can also access the temperature and sensor information by selecting the information button on the mode screen:

    A summary of the temperatures and sensors appears.

  4. Select Right arrow.

    A screen showing the highest relative humidity level measured by the humidity sensors opens.

  5. Select Right arrow.

    A screen showing the highest relative humidity level measured by the humidity sensors opens again.

  6. Select Right arrow.
  7. If the ventilation unit has an integrated carbon dioxide sensor or if an accessory carbon dioxide sensor has been installed, a screen showing the highest carbon dioxide level measured by the carbon dioxide sensors (ppm = parts per million) opens.
  8. Select Right arrow.
  9. A screen showing the highest carbon dioxide level measured by the carbon dioxide sensors opens again.
  10. Exit the menu by selecting Back:
