Information and Tips

Recommended Tip to Tip Deduction
1 1/8" - Using included Motor, Brackets, and End Plug

Tip to Tip Measurement: This is the measurement used for shades mounted within a window frame or within framed constraints. This is effectively the measurement from the outside edge of the brackets in a shade system.

Maximum Shade Width
App. 96" Tip to Tip

Maximum Width limitations are guidelines to minimize tube deflection and are not always a reflection of lifting capacity. The shade fabricator calculator below should be used to determine a system's limitations.

Note: We sell the motorized shade kits without consideration of use. Roller shade motors typically have a lifting capacity that out performs a tube's deflection. Tube deflection can cause ripples in the shade material and is based on the length of the tube and size (weight) of the shade.

Below is a generic guideline for max tube lengths based on the tube size.
   •  Shades up to 64" width - 1.25" Rollease Tube
   •  Shades up to 96" width - 1.5" Rollease Tube
   •  Shades up to 120" width - 2" Rollease Tube
   •  Shades up to 144" width - 2.5" Rollease Tube
   •  Shades up to 168" width - 3.25" Rollease Tube

Actual shade size, tube size and material should be used to determine the true limits of a system. The Shade Fabricator Calculator below will predict tube deflection (and more) based on tube size, material weight, width and height. Tube deflection is bending of the tube and causes ripples in the hanging shade material.

Shade Fabricator Calculator - (Excel Spreadsheet) - Calculates Roll Diameter, Shade Weight, Tube Deflection Etc.

The use of the internal hem bar requires a material formed pocket at the bottom of the shade. The hem bar pocket is typically formed by stitching or fusing the material. Alternative methods like double stick tape and adhesives can be used with some experimentation.

The motor and end plug slide into the tube without the use of tools. The included roller shade tube features double stick tape to securely attach your roller shade material. We recommend cutting the shade material height so a minimum of 1.5" extra wraps of material is left on the shade tube when the shade is fully down. This prevents the material from directly pulling on the tape.

* Projection Distance is the distance from the mounting surface to the center of the tube. You would need to shim the brackets or use larger projection brackets if half the roll diameter is larger than the projection distance of the brackets. If you do not know what your roll diameter is you can calculate the roll diameter using the shade calculator above.

About the Motor

The Somfy Sonesse 28 WireFree (ST28WF) RTS shade motor features a long life built-in lithium-ion battery. Say good bye to expensive external batteries. Lithium-ion battery technology is mature and has moved into motorized shade. The built-in lithium battery is expected to provide approximately 500 cycles of operation (depends on shade size) before needing a charge. That means you'll only need to plug in the optional external battery charger once a year or so.

The ST28WF RTS motor is a quiet radio frequency based motor for small to mid sized shades with its 1.1Nm lifting capacity. The Sonesse 28 motors are engineered with superior noise reduction technology. The compact, low profile Sonesse 28 motor is compatible with 1.5" Rollease tubes and is the perfect motor for shades 24" to 96" wide.

Radio Frequency: The Sonesse 28 shade motor is Radio Frequency based so you don't have to point the remote at it every time you want to control it. In fact, you can control the shades in your living room from your bedroom completely wirelessly. The motor stores the limits set by the remote controls. With the momentary press of a button you can command the shade to go to the Full up, Full Down and to a customer specified preferred position. No need to hold the button down and wait for the shade to reach the desired position.

Multiple Controls: The shade motor is controlled via Somfy's advanced (RTS) RF technology which offers the user simple individual or group control. Each motor can be controlled by more than one remote control. You can use one remote for local room based control and another remote for whole home control. The addition of the Somfy Mylink mobile device interface provides scheduled timers and conntrol from your phone or tablet from almost anywhere. Not at home and forgot to close a shade, not a problem with the MyLink.

Adjustable Speed: The Sonesse 28 series shade motors have adjustable rotation speed so you can closely match the speeds of other shades in the same room.

Soft Stop: The shade motor reduces speed as it nears a programmed stopping point to softly stop your shade.
