Installation Instructions
Professional installation is highly recommended for this product due to its electrical nature and specific wiring requirements. Always consult the detailed wiring diagrams provided with the physical product for precise connections and local building codes.
Ducting: This fan requires a 6-inch diameter duct for proper operation. Ensure the duct run is as straight and short as possible, with minimal bends, to maximize efficiency and airflow.
Mounting: The fan is designed for ceiling mount installation. Secure the fan housing firmly to ceiling joists or other suitable structural framing using appropriate fasteners.
Wiring: The ZN110H fan offers flexible control options, including configurations for one, two, or three wall switches. These configurations allow for control over master power, humidity sensing, and manual high-speed operation. Refer to the product's wiring diagram for specific connections.
Configuration Dials: Inside the fan cover, there are adjustable dials to set the configurable fan speed (between 50 and 110 CFM) and the humidity activation level (between 50% and 80% relative humidity). Adjust these settings to your preference before closing the fan cover.

Operating Instructions
The Broan-NuTone ZN110H fan offers versatile operation modes depending on your chosen wiring setup.
Single Switch Operation:
- ON/OFF: Turning the wall switch ON activates the fan at its pre-configured speed (between 50-110 CFM). Turning the switch OFF deactivates the fan.
- Humidity Sensing: If the humidity in the room rises above the set point while the fan is ON, it will automatically increase to 110 CFM until the humidity drops below the set point, then revert to the configured speed.
- Timed High Speed: To activate high speed for a set duration, turn the switch ON for more than one second, then OFF for less than a second, and back ON. The fan will run at 110 CFM for the configured time (between 5-60 minutes), then return to the configured speed.
Multi-Switch Operation (Recommended for full functionality):
For advanced and independent control, the fan can be wired with up to three separate wall switches:
- Master Power Switch: Controls the main power supply to the fan. When this switch is ON, the fan operates at the configured speed.
- Sensor Switch: When this switch is ON (and Master Power is ON), the fan will operate at the configured speed. If humidity rises above the set point, the fan increases to 110 CFM until humidity drops, then reverts to the configured speed.
- Manual-On Switch: When this switch is ON (and Master Power is ON), the fan runs at 110 CFM. When turned OFF, the fan continues at 110 CFM for a configurable interval (between 5-60 minutes) before reverting to the configured speed.
Quiet Operation: This fan is engineered for extremely quiet operation, with a low noise level of 14.4 Decibels, ensuring minimal disturbance.
Maintenance
Regular cleaning helps maintain the fan's performance, efficiency, and longevity. Always disconnect power before performing any maintenance.
Cleaning the Fan Grille:
- Turn off power to the fan at the circuit breaker.
- Carefully remove the fan grille from the ceiling.
- Wash the grille with a mild soap and water solution, then rinse thoroughly.
- Allow the grille to dry completely before reattaching it to the fan housing.
Cleaning the Fan Motor and Blades:
- Turn off power to the fan at the circuit breaker.
- Carefully remove the fan assembly from the housing according to the product's installation guide.
- Use a soft cloth or a small brush to gently remove dust and debris from the motor and fan blades. Do not use water or liquid cleaners directly on electrical components.
- Once clean, carefully reinstall the fan assembly and grille.
Troubleshooting
If you encounter issues with your Broan-NuTone ZN110H fan, refer to the table below for common problems and solutions. If the problem persists, contact a qualified electrician or customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power to the unit; loose wiring connection; faulty wall switch. | Check the circuit breaker for the fan. Verify all wiring connections are secure. Test the wall switch for functionality. If issues persist, consult a qualified electrician. |
| Fan runs continuously or at high speed unexpectedly. | Humidity sensor setting is too low; high ambient humidity in the room; manual-on timer is active. | Adjust the humidity sensor dial to a higher percentage. Ensure the bathroom humidity has dissipated. Check if the manual-on switch was recently used, activating the timed high-speed function. |
| Fan is noisy or vibrates excessively. | Loose mounting of the fan housing; debris or obstruction in the fan blades; improper ducting installation. | Ensure the fan housing is securely mounted to the ceiling joists. Turn off power and clean any debris from the fan blades. Verify the 6-inch duct is properly installed, free of kinks, and not obstructed. |
