Attractive New Look A dramatically new automated ceiling register design replaces those antiquated metal registers of yesteryear that collect dust, rust and whistle when closed. This new aerodynamically smooth design provides a pleasingly sleek look that blends well with any décor. The registers are molded from durable, rust-free ABS plastic in a ceiling white color that can also be painted or stained to match existing colors. Lower-cost, manually controlled versions are also available to maintain this exciting new look throughout any structure.   Improved Comfort Conditioned air is only provided where and when it is needed, which eliminates the energy waste associated with heating or cooling an entire structure. The aerodynamic design of the MicroFlow 2000TM ceiling register bathes the entire room. This eliminates the chilling effect created by conventional louvered registers, particularly when heat pump systems are used.   Significant Energy Savings Using whole-house day/night zoning, average HVAC system energy savings of 25% or more have been measured over complete cooling and heating day periods. During periods of peak demand, savings of 50% have been demonstrated. The low system purchase price combined with this dramatic energy savings provides a rapid return on investment and improved comfort.   Easy to Install Installation is identical to conventional registers using two screws. On the back of each register are reference bosses that can be easily drilled to fit standard register plate hole patterns. For automated registers, a single modular telephone cable is routed through the attic crawl space and then through a small opening in the duct near the register box. From inside, the modular cable is plugged into one of two modular (telephone type) jacks on the register and the register is mounted using two screws provided. The two jacks provide the option of setting each register to “normally closed” or to “normally open” when the system control switch is “off.” Modular Tee connectors are used to provide convenient connections for a short “drop” cable at each register location. The modular cable supplying the registers is plugged into a small “PowerHubTM” control module, which is then connected to a 24 VAC plug-in transformer. Connecting a standard wall switch completes the installation to the PowerHubTM, again using modular cable and connectors.   Homeowner Friendly There are no expensive and complicated central control panels to program or connect to the HVAC system. The control electronics fit inside a hand-held, plug-in PowerHubTM module. Connections to the power module are all via modular telephone connectors. A single room or a complete home or office can be controlled with a single contact closure. The closure can be provided from a wall switch, a programmable thermostat or timer, a home automation system such as X10* or any other device that can provide a closure.   Easy to Clean and Maintain The smooth contoured surfaces at the ceiling reduce dust collection and they are easier to clean. A simple pole-mounted dust mop is all that is needed to clean the surfaces. There are no metal parts to rust or collect dust. The actuation mechanism uses a highly reliable timer motor and mechanical components that do not require lubrication. If service is required, all components are easily accessed from inside the room, not the attic.   Flexible Zoning Capabilities A MicroFlow2000TM zone can be as small as a single room or as large as needed. Day/Night or other types of complement zoning assignments are accomplished at each register by connecting the modular drop cable to the appropriate jack. Constant systems airflow is provided by allowing flow to be reduced in one zone as it is simultaneously increased in the other (complementary) zone. Room by room zone assignment throughout the structure can be made without regard to how the duct work is distributed or where the rooms are located.
