Abstract:
A battery-powered infrared remote-control motorized lift window treatment assembly comprising:a head rail having a rod rotatably disposed therein, said rod defining a longitudinal axis;a dc motor disposed in the head rail and coupled to the rod to rotate the rod;a window covering operatively engaged to said rod and arranged to be selectively raised and lowered upon rotation of said rod;at least one battery mounted in the head rail;an infrared receiver having a power supply lead, a ground lead and an output lead, said infrared receiver configured to detect and demodulate a user-generated infrared light signal from a remote control transmitter, and output a sensed remote control signal in response thereto;a manual switch configured to output a manual control signal each time said manual switch is activated; anda programmed processor having associated therewith a non-volatile memory configured to store executable software code for controlling the assembly, said programmed processor also having a plurality of connections including:a ground connection;a voltage supply input;a remote signal input configured to receive said sensed remote control signal from said output lead of the infrared receiver,a manual signal input configured to receive said manual control signal from said manual switch;a voltage output configured to connect power to the power supply lead of the infrared receiver; andfirst and second motor drive signal outputs, each motor drive signal output configured to output a motor drive signal to energize the motor to turn in one of two directions, in response to either a valid sensed remote control signal or a manual control signal, wherein the infrared receiver is not powered at all times.
