Positive voltage on one side of the cable means that the shade goes up. This motor is controlled by by reversing polarity of a 2 conductor cabling. The other type of shade does not have a module built into the shade, only a motor. These shades are more expensive to cable for, more expensive to purchase, more expensive to maintain, and much more of a hassle to integrate with an automation system since the communication protocol is up to the manufacturer and may not have a direct integration with the automation system. These systems only need power and a way to communicate with a control system. Locally controlled shades are wires for power and have a module build into the shading enclosure that controls the shade motor telling it to go up or down. The most common shading systems can be divided into two categories, locally controlled shades and remotely controlled shades. With that being said, there are systems that are more common than others and some that are superior. If there are conflicts please inform us so that they will be addressed. If the wrong method of dimming is used, such as an incorrect bulb type, equipment will be damaged.
