5. Operating Instructions

The Honeywell Home HE360A1075 operates in conjunction with your furnace to introduce moisture into your home's air circulation system.

5.1 Humidistat Control

The H8908 Humidistat allows you to set your desired humidity level. It senses the relative humidity in your home and activates the humidifier when the humidity drops below the set point and the furnace fan is operating. Adjust the humidistat setting based on outdoor temperature to prevent condensation on windows and walls.

• Setting the Humidistat: Rotate the dial to your desired humidity percentage. Start with a lower setting (e.g., 30-35%) and gradually increase if needed.
• Automatic Operation: The humidifier will automatically turn on when the furnace fan runs and humidity is required, and turn off when the set humidity is reached or the furnace fan stops.

6. Maintenance

Regular maintenance ensures efficient and reliable operation of your humidifier. The flow-through design helps minimize mineral buildup, but periodic cleaning and pad replacement are still necessary.

2. Remove Cover: Open or remove the humidifier cover.
3. Remove Old Pad: Carefully slide out the old humidifier pad and its frame. Dispose of the old pad.
4. Clean Tray: Clean any mineral deposits from the water distribution tray and humidifier housing.
