Please Read Prior to Installing This Fan

Spot and Continuous Ventilation: These fans are designed to run continuously, ensuring a healthy environment at low CFM levels 24 hours a day. By utilizing the optional CustomVent Multi-Speed module, 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.

CustomVent Multi-Speed Module (Lower Setting) ASHRAE 62.2-2016

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.

Feature

Optimum Ventilation Performance

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.

Outstanding Energy Savings

The WhisperGreen Select Line of fans 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

All the WhisperGreen Select base models of fans come with Pick-A-Flow speed options. The Pick-A-Flow switch on the face of all WhisperGreen Select fans allows the option to choose 50 – 80 – 110 CFM for the FV-0511VK2, FV-0511VKS2 or 110 – 130 – 150 CFM for the FV-1115VK2. These fans can run continuously or intermittently, depending upon the needs of the owner.

Air volume type (CFM)

Indication (Plug 'N Play Function Devices)

Note: There is ONLY ONE Plug 'N Play slot to insert the Multi-Speed module within the base model fan. There are TWO interchangeable Plug 'N Play slots to insert the Condensation Sensor module, Motion Sensor module within the base model fan.

FV-VS15VK1 Multi-Speed module allows the fan to run continuously at lower speeds to maintain ventilation standards to meet Indoor Air Quality and then boost up to high speed to meet intermittent needs for ‘Spot’ or 'Point Source' exhaust needs. The FV-VS15VK1 Modular Component will operate for both the FV-0511VK2 and the FV-1115VK2 matching the appropriate Multi-Speed setting shown below. The FV-0511VKS2 comes with the FV-VS15VK1 Multi-Speed module. It is not necessary to purchase this component.

Note the options on the face of the FV-VS15VK1 Multi-Speed module to choose appropriate levels of airflow (CFM) and time delay before returning back to low speed (TIME). Choosing the Pick-A-Flow setting automatically adjusts the Multi-Speed setting accordingly. As an example, if the Pick-A-Flow Multi-speed setting is 80 CFM, the Multi-Speed settings adjust automatically to be 0, 30, 40, 50, 60 or 70 CFM at the lower speeds. The fan will ‘boost’ to the 80 CFM speed as the high speed setting. Selecting a particular TIME option will cause the fan to run for the selected amount of time before returning to the lower speed setting chosen on the CFM dial.

Delay Time (min)

FV-CSVK1 Condensation Sensor module turns the base fan on or boosts to higher speed when humidity is detected when used in combination with the FV-VS15VK1. The Condensation Sensor works based on calculations from the Psychrometric Chart, or combination of Relative Humidity (RH) and Temperature. This allows the fan to anticipate the formation of condensation and automatically turn on when needed to expel humid air. The Condensation Sensor is pre-set to run for 20 minutes; it will then check the RH and Temperature to detect if the fan needs to run for another 20 minutes cycle.

Practical Guide to Installation

Properly insulate the area around the fan to minimize building heat loss and gain. (Fig.19) Loose fill or batt insulation can be placed directly over the fan housing in the attic. Panasonic fans do not create excessive heat that is a common problem with recessed light fixtures or some competitor's fan/light combinations. Panasonic's efficient, cool-running motors do not create enough ambient heat to be subjected to these limitations.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise, and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.
