1. Introduction
Thank you for choosing the iO-FCA Filter Change Alert from iO HVAC Controls. This device is designed to provide both a visual and audible reminder when it is time to replace your HVAC system's air filter. By ensuring timely filter replacement, the iO-FCA helps maintain proper airflow, static pressure, and indoor air quality, contributing to the efficient operation of your HVAC system. Please read this manual thoroughly before installation and operation to ensure correct usage and optimal performance.
2. Product Overview
The iO-FCA Filter Change Alert monitors the condition of your HVAC filter by detecting changes in static pressure. As the filter accumulates dust and debris, it becomes clogged, leading to decreased system efficiency and increased static pressure. The iO-FCA, when paired with a static pressure switch (sold separately or integrated into your system), tracks this pressure change and activates an alert when a filter replacement is necessary.
2.1 Key Features
- Visual and audible filter change reminders.
- Audible beep can be silenced with a button press; red light remains active until filter is changed.
- Detects the degree of filter clogging based on static pressure.
- Helps maintain HVAC system efficiency and air quality.
2.2 Product Components
The iO-FCA Filter Change Alert unit includes the main alert device. A static pressure switch is required for operation and is typically integrated into the HVAC system or purchased separately.

3. Setup and Installation
Installation of the iO-FCA Filter Change Alert should be performed by a qualified HVAC technician. Ensure all power to the HVAC system is disconnected before beginning installation.
- Mounting: Select a suitable location near the HVAC unit where the alert can be easily seen and heard. The device can be mounted using the integrated mounting tabs.
- Wiring to Static Pressure Switch: Connect the iO-FCA to a compatible static pressure switch. The alert unit typically requires a low-voltage connection (e.g., 24VAC) and inputs from the static pressure switch. Refer to the wiring diagram provided with your static pressure switch for specific connection points.
- Power Connection: Connect the iO-FCA to the appropriate power source as specified in the wiring instructions.
- Testing: After installation, restore power to the HVAC system. The unit should perform an initial self-test. Consult your static pressure switch manual for calibration or initial setup procedures to ensure proper detection thresholds.
Note: Incorrect wiring can damage the device or the HVAC system. If you are unsure about any step, consult a professional.
4. Operation
4.1 Normal Operation
Under normal operating conditions with a clean filter, the iO-FCA will remain inactive, indicating that the HVAC system's airflow is within optimal parameters.
4.2 Filter Change Alert Activation
When the static pressure across the HVAC filter reaches a predetermined threshold, indicating a clogged filter, the iO-FCA will activate:
- An audible beep will sound periodically.
- A red indicator light will illuminate on the device.
This dual alert system ensures you are promptly notified that your HVAC filter requires replacement.
4.3 Silencing the Audible Alert
To temporarily silence the audible beep, press the red button located on the front of the iO-FCA unit. The audible alert will cease, but the red indicator light will remain illuminated. This serves as a continuous visual reminder that the filter still needs to be changed. The audible alert will reactivate after a set period or upon system reset if the filter is not replaced.
4.4 Resetting the Alert
The alert will automatically reset once a new, clean filter is installed and the static pressure returns to normal operating levels. No manual reset is typically required after filter replacement.
5. Maintenance
- Filter Replacement: The primary maintenance task is to replace your HVAC filter promptly when the iO-FCA indicates it is dirty. Refer to your HVAC system's manual for specific filter types and replacement procedures.
- Cleaning: Periodically wipe the exterior of the iO-FCA unit with a soft, dry cloth to remove dust. Do not use abrasive cleaners or solvents.
- Inspection: Annually inspect the wiring connections to the iO-FCA and the static pressure switch to ensure they are secure and free from damage.
