Clear kitchen countertops do wonders for efficiency when you are trying put together a meal. No matter what kind of cook you are, there is a good chance that you own at least a blender, some sort of chopper and maybe even a mixer. The difficulty in owning these appliances is finding space to store not only the container, but the bulky base that houses the motor needed to blend, spin, chop or mix with these appliances.

With the TCC Kitchen Center however, a single base is shared amongst all of these appliances which can be mounted either in the countertop or a pullout drawer further maximizing counter space and promoting a clean look.

Breath Easier With Broan

Now homeowners have an automatic, affordable, energy-efficient solution to improve the home's Indoor Air Quality (IAQ) and increase energy savings with the Broan SmartSense Ventilation System.
"As energy conservation and IAQ continue to be a hot topic, the Broan SmartSense System is the perfect solution to exhaust stale indoor air and minimize opportunities for mold and mildew growth in the home," according to Tom Heidel, marketing manager, IAQ, Broan-NuTone. "Pollutants such as carbon dioxide, carbon monoxide, volatile organic compounds and excess moisture are not removed by the filtration units and air cleaning machines that have become so popular today."
According to studies from the American Society for Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), a single fan system does not provide effective continuous ventilation. This innovative breakthrough in ventilation technology has combined the patent-pending Broan SmartSense technology with Broan Ultra Silent™ ventilation fans to create an integrated ventilation system in the home. Individual fans that once worked independently now work together to ensure fresh air throughout the day.
Incorporating this intelligent ventilation into the home is easy. The first step is to have Broan Ultra Silent™ SmartSense fans installed anywhere in the home where ventilation is needed. Next, a Broan SmartSense control is connected to each fan. Using the ASHRAE formula based on the size of the home, the ventilation rate is entered into one of the controls. The remaining controls communicate through the use of Broan-NuTone's LinkLogic System– the INSTEON-enabled communication technology that digitally communicates over already installed power lines. No wires are needed, resulting in a ventilation system that blends seamlessly into the home or apartment.
Additionally, the Broan SmartSense can be used as a single fan ventilation solution for small spaces or combined in any combination to create an integrated ventilation system for larger homes or multi-family residences.

The Broan® SmartSense® Ventilation System improves air quality throughout the home Additional unique features of the Broan SmartSense System include:
  • Efficient energy management – saves millions of cubic feet of excess ventilation per year and many energy dollars
  • Use of less than 35 watts during ventilation cycles compared to others that can use up to 500 watts or more
  • Continually monitors and activates fans day and night – operating only when necessary
  • A three-year warranty

Proper Installation Makes all The Difference.

Proper installation makes all the difference
Key installation tips:
  • Keyhole slots and alignment tabs facilitate installation, taking the guesswork out of proper mounting.
  • Elbows, turns, long ducts and ductwork smaller than the fan's exit outlet will reduce performance.
  • Use Wide aluminum foil or duct tape to join smooth metal ductwork seams.
  • Do not let flexible ductwork sag as this impedes airflow.
  • During installation, orient the bath fan outlet in the direction of the home's exit point to minimize duct turns.
  • Before adding an elbow or bend, allow 24" to 36" of straight run from the fan outlet point.
  • Duct-wrap insulation (R-5 or above) will help minimize condensation in cold climates, especially on long duct runs.
  • Exit vents should have backdraft flaps to help keep cold air from entering duct.

Ventilation Controls


As buildings become increasingly airtight, awareness of mechanical ventilation grows. Proper ventilation is essential for removing excessive moisture that promotes mold and mildew buildup, which can deteriorate a building's structure. Mechanical ventilation also helps remove accumulated volatile organic compounds (VOCs) that affect indoor air quality (IAQ) and may cause health problems for occupants.

Different lifestyles place different demands on the ventilation system. For example, a single adult, most likely, will require less ventilation than a family of five with pets. Also, an adult homeowner may be more likely to properly operate a manual ventilation control than a tenant or children that share a bathroom. Therefore, selecting a suitable control that runs ventilation at the proper time and duration will ensure that both the occupant's health and building structure are protected.

There are several types of manual and automatic controls that can be applied to ventilation systems. Some controls are more suitable for intermittent or continuous ventilation. Panasonic's new WhisperGreen® Premier fans incorporate built-in speed, delay and occupancy controls, making them ideal for both intermittent and continuous ventilation. The following discusses options to help select a suitable control.

Manual Controls:
Manual controls require the occupant to activate the ventilation fan when needed. This allows people who are particularly sensitive to indoor air quality to manually control and maintain their comfort level. The disadvantage of manual controls is that some people may not sense the need for ventilation and not turn it on. The basic manual control is an on/off toggle switch. However, there are other controls with functions that may be more suitable to the occupant's lifestyle.

Delay timer:
Shower curtains, towels, walls and cabinets retain moisture long after the occupant has finished and left the bathroom. The advantage of a delay timer is that it continues to evacuate moisture and odor after the occupant has finished. WhisperGreen® Premier fans incorporate a delay timer that can be set within the range of 30 seconds to 60 minutes for the desired delay effect.

Manual timers:
There are two basic types of manual timers. The less expensive are spring-wound, known as crank timers, suitable for intermittent bathroom ventilation. Electronic timers are more decorative and expensive but allow the occupant to select a time duration with the push of a button. Electronic timers do not produce the sometimes annoying ticking sound that crank timers are known for. WhisperGreen® Premier fans incorporate quiet electronic controls.

Speed controls:
Speed controls allow the user to set the desired speed (airflow) of a ventilation device. Speed can be controlled either continuously or in steps. One of the disadvantages of speed controls is that they can cause undesirable noise when working in conjunction with the fan's AC motor. WhisperGreen® Premier fans incorporate a DC motor that operates quietly with its own built-in controls.

Automatic Controls:
These controls can be full or semi-automatic. An example of a fully automatic control is a 24-hour duty cycle timer that is programmed to cycle on and off over a 24-hour period. A semi-automatic control is a control that has an override switch. An example would be an occupancy sensor with a manual on/off override.

Occupancy (motion) sensors:
Occupancy sensors are suitable for intermittent ventilation. An advantage is that the ventilation system will operate without having to rely on the occupant's interaction. The ventilation system will remain "on" and continue working for a duration after the occupant has left the room, much like a delay off timer. Select WhisperGreen® Premier fans have occupancy sensors integral to the fan grille. Dehumidistats can be used to turn a ventilation system on/off when relative humidity reaches a certain level. These controls are most likely to be used in bathrooms to evacuate excessive moisture. Dehumidistats have a few disadvantages. One disadvantage is that seasonal changes in outdoor relative humidity necessitate seasonal readjustments to function optimally. Another disadvantage of a dehumidistat is that they are often mistaken for thermostats and set at 70 and never adjusted. Finally, it does not automatically remove odors.
