Motorized Hunter Douglas shadings, shades and blinds are designed for ease of operation and precise control. With remote-control units, operating functions are served by a hand-held remote transmitter and a remote receiver mounted near the shading. A single remote transmitter can operate up to 12 shadings. With switch-control motorized units, a three-position switch is used to operate each shading.

The lower travel limits of motorized shadings are pre-set at the factory. Buttons on the motor assembly provide for adjustment of the lower travel limit after installation, if necessary.

Upper travel limits of motorized shadings are controlled by a stall sensor unit. The sensor prevents the motor from continuing to run after the shading is fully raised.

There is one stall sensor unit for each shading. It is located next to the control unit (remote control) or on the back of the switch plate (switch control).
