5. Operating Instructions
The VELLEE Register Booster Fan features smart thermostat control and a remote for easy operation.
5.1 Powering On/Off
Press the power button on the remote control or the fan's control panel to turn the unit on or off.
5.2 Setting Temperature Control
The fan is equipped with a high-sensitivity temperature sensor and a smart chip. It can automatically start and stop based on your desired temperature settings.
- Use the temperature adjustment buttons on the remote or fan panel to set your desired temperature threshold.
- In cooling mode (summer), the fan will activate when the room temperature exceeds your set point, helping to draw cool air into the room.
- In heating mode (winter), the fan will activate when the room temperature falls below your set point, helping to push warm air into the room.

5.3 Adjusting Fan Speed
The fan offers 10 adjustable speed levels. Use the speed control buttons on the remote or fan panel to increase or decrease the airflow. Lower speeds result in quieter operation (as low as 18 dBA).
