Duct length, elbows and other factors increase static pressure which can hinder the performance of most ventilation
fans. This fan utilizes Smart Flow™ microchip technology that monitors the static pressure in the system and speeds
up or slows down the rpm of the fan depending upon the amount of resistance within the ducts. This feature allows
the fan to perform as rated and avoid potential installation issues.
These products are built using DC motor technology. The DC motor is 30% ~ 70% more energy
efficient than the minimum ENERGY STAR requirements.
Pick-A-Flow™ Feature:
This product comes with Pick-A-Flow™ speed
options. The Pick-A-Flow™ switch on the face of the product allows the
option to choose 80 or 110 CFM.
This product can run continuously or intermittently, depending upon the
needs of the owner.

The product will continue to run for about
20 minutes after the sensor detects that
the humidity is ~5 % RH lower than the
humidity setting before stopping.

Note:
1. The power switch should be left on at all times.
2. The product will also run when the humidity rises rapidly but does not reach the humidity trigger setting, and then stop after
the time delay.
3. The activation humidity settings on the dial are continuous from 30 %RH ~ 80 %RH.
4. The humidity detected by the sensor may differ from the value on your hygrometer.
5. The product may cycle on and off if the humidity is constantly near the trigger point. This can be addressed by raising
the humidity trigger setting on the dial.
6. The fan will run for 20 minutes when power switch is first turned on, regardless of the humidity sensor settings. After 20
minutes, the fan will return to sensor mode.
