## Description

A quiet fan system designed for improving wall and floor register airflow from HVAC systems. Programmable LCD controller with heating and cooling thermostat, and automated fan speeds. Premium anodized aluminum frame with CNC-machined detailing and a brown bronze finish. Features stator-blade fans which can deliver strong airflow from high static-pressure ductwork. Fits ONLY 4 x 10 in. Registers | Airflow: 120 CFM | Noise: 18 Dba | Includes Wall Adapter Product Description A quiet fan system designed to be mounted onto wall or floor registers to boost airflow. By increasing warm and cool air coming from weak registers, you can increase room comfort and reduce energy costs. Features a LCD display with smart thermostat control and customizable fan speeds. The mounting frame is constructed of bronze-anodized aluminum with CNC-machined detailing and a brushed finish for a professional appearance. Features PWM-controlled stator blade fans that are designed for high static pressure applications such as ducting. Includes hardware and power supply needed to secure the unit onto an existing register opening and power it through an outlet. Intelligent Programming The controller on each unit features active thermal monitoring that can trigger fans to run for both cooling and heating temperatures you have set. The controller can also be set to run continuously at speeds manually. Features temperature display, easy power on-off, and backup memory. Stator-Blade PWM Fans The system utilizes high-performance DC-motors that are controlled using PWM (Pulse Width Modulation). This technology enables the dual 92mm fans to be able to run smoothly at extremely low RPM speeds without generating motor or electromagnetic noises. In addition, the fans feature a stator-blade design with a high static pressure rating, specialized for delivering airflow even in applications where air movement is being restricted such as through ductwork. The motor houses dual ball bearings that are rated at 67,000 hours and allow the fan system to be mounted horizontally or vertically, which are certified by CE and RoHS.

## Questions & Answers

**Q: Give me an example of your temperature settings?  I’m confused on how to set it.**
A: There are three settings that can be adjusted: Fan speed, Cooling Temperature Threshold, and Heating Temperature Threshold.  The manual recommends only having the heating OR cooling thresholds set at one time, but as long as you keep a large enough temperature differential between them you shouldn't have issues.  If your room temperature is currently 72 degrees, and you turn on your AC you would want to set the cooling temperature to something like 65 degrees.  This way, when cold air from the AC begins to pass through the vent, the displayed temperature will begin to drop from 72 down to 65 degrees and below (because the air from AC is much colder than 65).  When the vent registers the temperature is 65, it will kick the fans on for all temperatures colder than 65.  The fans will stay on until enough time has passed when the AC is off that the temperature gets warmer than 65.  Likewise for heating, you would want to set a temperature like 80 degrees, so that when the heater begins blowing warm air and the vent registers that the temperature has raised, it will be on as long as the temperature at the vent is warmer than 80 degrees.

**Q: Will this work well with a geothermal system that does not output as extreme temperatures as a traditional gas/electric heater?**
A: Yes. I have a geothermal system (WaterFurnace), and haven’t had a problem with the unit starting when heat kicks on. It’s made a noticeable difference in the room (furthest from furnace) where we are using it. Well made unit, impressive packaging.

**Q: Can it be used in the floor where it might be stepped on?**
A: It is very sturdy, but if you step on the digital screen and buttons it may crack. Also, wouldn't recommend placing in a traffic area because of the cord that runs to wall outlet. Really solid system.

**Q: Do you have a version of this for a baseboard unit?**
A: No
