This article is intended for representatives, dealers, and Lutron Pros who are qualified to install and program Lutron shading solutions. 

If you are a homeowner or end-user and your Lutron shades are moving at different speeds, please contact your Lutron dealer for assistance. If you are unsure who your dealer is, visit lutron.com/wheretobuy to generate a list of local Lutron shades dealers. 

Before You Begin

Before using the Intelligent Hembar Alignment (IHA) tool, verify the following:

• You are on site. The IHA tool does not function remotely.
• All shades are activated.
• All shades have their open and close limits set.
• You have access to the project file.
• The processor’s firmware version and the Lutron Designer software version match and are up to date.
• The PC is connected to the same network as the processor — verify the LAN Status is “Good” in the activate tab.

How to Use The IHA Tool

1. From Lutron Designer, click Tools, then select Set Shade Speed Alignment (IHA).

2. Select the shade you are programming from the room tree in the top left-hand corner

3. Verify the current IHA settings of the shade 

4. Ensure the shade is at the default IHA setting

5. Take the Close Limit, Calibration Point, and Open Limit measurements and input them into the appropriate fields.

    Note: Precise measurements (within 1/16") are critical to achieving accurate speed alignment.  

1. Click Go Close to move the shade to the close limit. Then, measure the distance from the reference point to the close limit and enter the value in the appropriate field.

Note: The reference point should be the most level platform. If there is not a level surface, measure ceiling to floor at far left and far right shades and note the difference.

2. Click Go Cal.Pt. to move the shade to the calibration point. Then, measure the distance from the reference point to the calibration point and enter the value in the appropriate field.

3. Click Go Open to move the shade to the open limit. Then, measure the distance from the reference point to the open limit and enter the value in the appropriate field.

5. Click Calculate to generate your new IHA settings

6. Click Send to Shade to set the new parameters for the shade

7. The new IHA Parameters are now set. Test the shades from System Shade Control to verify accurate alignment
