These fans are also built to take care of the homeowner’s spot ventilation needs when the room is
occupied. The basic fan models allow a choice of three speeds. When fans are equipped with the optional
Multi-Speed module, these models kick up to a maximum level of 150 CFM for the FV-1115VK2 and 110
CFM for the FV-0511VKS2 and FV-0511VK2 either when the switch is turned on or activated by the
optional Condensation Sensor module or the optional Motion Sensor module.
A High/Low Delay Timer, located inside the fan unit, is utilized to return the fan back to the pre-set
Continuous ventilation mode. The installer needs to consult with the homeowner for the desired
setting on the timer (0 - 60 minutes) and make the adjustments during the installation.

DESCRIPTION
These products are listed by UL under UL file No. E78414.
These products use a sirocco fan driven by a DC motor powered by an integral transformer. The motor is
designed to have long operating life, high dynamic response, higher speed ranges with saving energy.
The grille covering the fan body is a spring-loaded, quick remove type. A damper for preventing air counter
flow is provided. The blower uses a high-capacity sirocco fan developed to reduce the noise level.
the fans are built to run continuously at a pre-set lower level (FV-0511VKS2 and FV-0511VK2: 0, 30,
40, 50, 60, 70, 80, 90, 100 CFM; FV-1115VK2: 0, 50, 60, 70, 80, 90, 100, 110, 120 CFM). The setting is
dependent on the size of the house and the individual wishes of the homeowner. It is crucial that the
installer pre-set the lower setting during the installation. Please refer to the chart below and the
switch indication on page 6.
