6.1 Setting Desired Humidity

  1. Locate the digital humidistat, typically mounted on an interior wall or the return air duct.
  2. Use the Up/Down arrow buttons to adjust the desired humidity percentage. The humidistat will display the current indoor humidity and your set point.
  3. The outdoor sensor helps the humidistat automatically adjust the indoor humidity set point to prevent condensation on windows during colder outdoor temperatures.

6.2 Automatic Operation

Once the desired humidity level is set, the system will automatically turn the humidifier on and off as needed to maintain that level. The humidifier will only operate when the furnace fan is running and humidity is required.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your humidifier.

7.1 Humidifier Pad Replacement

The humidifier pad (also known as the evaporator pad or water panel) requires seasonal replacement. This is typically done at the beginning of each heating season or every 1-3 months depending on water quality and usage.

  1. Disconnect power to the furnace and humidifier.
  2. Open the humidifier cover.
  3. Remove the old humidifier pad and discard it.
  4. Install a new, genuine Honeywell replacement pad, ensuring it is correctly oriented.
  5. Close the cover and restore power.
