Setup and Installation
The VIVOSUN Quiet Register Booster Fan is designed for easy installation into standard 4"x10" register holes. It can be mounted on walls or floor registers.
1. Verify Register Size
Before installation, measure your existing register hole to ensure it is 4 inches by 10 inches for a perfect fit. The fan unit itself measures 11.8 inches in length and 5.5 inches in width, with a depth of 3.93 inches for the fan housing.

2. Placement
The fan can be placed directly into a floor register opening or mounted onto a wall register. Ensure the 12 ft power cord can reach a power outlet without being strained or creating a tripping hazard.

3. Power Connection
Connect the provided 12 ft power cord to the fan unit and then plug it into a standard electrical outlet.

Operating Instructions
The VIVOSUN booster fan features an intelligent LCD controller for easy programming and operation.
1. Power On/Off
Once plugged in, the LCD screen will illuminate. Use the power button (usually indicated by a circle with a vertical line) to turn the unit on or off.
2. Setting Temperature Thresholds
The fan can be programmed to activate automatically based on temperature. Use the up and down arrow buttons on the LCD controller to set your desired cooling or heating temperature thresholds. The integrated high-precision thermal probe will monitor the ambient temperature.

3. Adjusting Fan Speed
The fan offers 10 adjustable speed settings. Use the appropriate button (often labeled with a fan icon or 'Mode') to cycle through the speed options and select your preferred airflow intensity. The PWM-controlled motor ensures precise speed control.

4. Balancing Room Temperatures
The primary function of this fan is to boost the airflow from your HVAC system, helping to redistribute warm or cold air more effectively. This can lead to more balanced room temperatures and potentially reduce energy consumption.
