ULTRASense™ M, Motion Sensing Technology, offers a hands-free solution for maximum convenience. The fan will increase to maximum speed from the lower, continuous setting when motion is detected -- which is ideal for family members who forget to turn the fan on -- and will stay on the max setting for the user-set 5-60 minute period after no motion is detected, before falling back to the continuous setting. Multi-Speed operation handles demanding spot ventilation needs, but can also pull double-duty as a great continuous ventilation solution to meet today’s stringent requirements. Upon installation, a continuous CFM adjustment dial is set to precisely control the airflow for the size of your house – so you’ll enjoy a successful inspection and not over-ventilate. A timer dial (adjustable from 5-60 minutes) is set at the same time to control how long the fan runs at maximum CFM, before automatically returning to the lower continuous ventilation level – all after you leave the room. ULTRALucent™ Lighting Technology provides 36 watt lights (two 18-watt bulbs included) delivering the brightness (measured in lumens) of models previously requiring 60 watts of CFL output .You get the best of both worlds; clear, even lighting with no hot spots and smaller energy bills. ULTRASilent™ with QStream™ Sound Technology results in operation at less than 0.3 Sones – the quietest sound rating attainable for an environment that is so quiet, you’ll likely forget the fan is on. ULTRAQuick™ Installation Technology uses an exclusive telescoping mounting frame with pre-installed screws, snap-in housing, snap-in blower and an inside-out mounting duct connector making installation up to 60% faster in retrofits and up to 20% faster in new construction, saving you time, money and aggravation. ULTRASmart™ DC Motor & Control Technology provides energy efficiency almost 10 times greater than Energy star® requirements and maintains rated power (CFM) in nearly every installation. You have confidence you’re getting the expected performance and won’t even notice the fan usage on your utility bill. Snap-in housing and blower further simplify installation since you can hear and feel when they are properly seated. Easy-to-position carriage allows housing location adjustment between joists so you can control the correct ceiling placement.
