To adjust the humidity level on your Fantech 415517 EDF8 Electronic Multifunction Dehumidistat, follow these steps: First, press and hold the 'Auto' button until the 'SET' icon appears on the display. Next, use the 'UP' and 'DOWN' arrow buttons to adjust the relative humidity setpoint to your desired level. To confirm your setting, either press the 'AUTO' button once or simply wait for the 'SET' icon to disappear. Once confirmed, the display will show the current indoor relative humidity. Please note the displayed relative humidity is accurate to within +/- 5%. Factors like airflow and local heat sources can slightly affect the reading. If the room's humidity is higher than your setpoint, the dehumidistat will activate the ventilation mode at normal speed, bringing in fresh air to lower humidity. If the outdoor air is more humid, high-speed ventilation might increase indoor humidity; in this case, deactivate the humidity setpoint by pressing the 'AUTO' button once. This will make the 'HUM' icon and humidity value disappear, indicating the setpoint is off. Reactivate by pressing 'AUTO' again. For optimal performance, always refer to the Fantech manual. If you see error code 01, try disconnecting the power to the HRV/ERV for 10 seconds, then reconnecting it. For more assistance, consult Fantech's contact information.
