Installation walk-through for 048561
Lutron document 048561 gives six steps, in the document's order.
The clearance, the check and the warning under a step are the document's own.
Get a matched set of new batteries
Lutron document 048561 swaps all the batteries in a shade together for brand-new, unopened ones from one package.
Each should expire no sooner than 7 years after installation, because stored batteries slowly drain. Buy a well-known brand.
Warning: Never mix manufacturers or types, such as lithium with alkaline.
Fit every battery the right way round
Check the orientation of each battery as it goes in. Lutron notes that a shade may still power up and run with one or two batteries reversed.
Warning: Reversed batteries cut battery life significantly.
Use the right chemistry
D-cell shades take alkaline batteries; Lutron names Duracell Coppertop. AA-cell shades run on alkaline but last longer on lithium; Lutron names Energizer Lithium AA.
Warning: No carbon-zinc, lithium or rechargeable D cells.
Reject damaged or expired cells
Look over each battery before fitting it. Set aside any battery that is expired, dented, scratched or has a damaged label, corroded terminals or leakage.
Check the shade and its travel
Watch the blink codes and movement speed to know when batteries need changing. Keep the shade clear of snags along its travel.
On a honeycomb shade, do not set the open limit so tight that the hembar squeezes the fabric.
Check: After opening, the honeycomb fabric does not relax and the drive LED does not blink red.
Wake a hibernated shade
A shade at battery end of life stops answering commands and shows no LED. Remove the old batteries and wait 5 minutes before fitting new ones.
On shades made in 2014 or later, fit the new batteries at once, then press and release the shade button.
Check: The shade leaves hibernation and runs normally.

Which roller shades does 048561 cover?
Lutron Triathlon roller shades.
How do sensors affect shade battery life?
Lutron document 048561 explains that a battery shade wakes for every Lutron radio signal on its channel.
Sensors transmit far more often than keypads. In larger systems Lutron puts wireless daylight, window and temperature sensors on a separate RF link from the shades.
Which batteries should go in a Lutron D-cell shade?
Lutron document 048561 recommends alkaline D cells, all new from one package with at least 7 years to expiry. Lutron names Duracell Coppertop and rules out carbon-zinc, lithium and rechargeable D cells.
What if a shade stops responding and shows no LED?
Lutron document 048561 treats a dark, unresponsive shade as hibernating at battery end of life.
Lutron removes the old batteries and waits 5 minutes before fitting new ones. Shades made in 2014 or later take new batteries at once, then one press of the shade button.
What does a red blink every 5 seconds mean?
Lutron document 048561 reads a red blink every 5 seconds as low batteries, solid red during movement as very low.
- Low batteries: replace within 3 months
- Very low batteries: replace within 2 weeks
How many movements a day does Lutron's battery estimate assume?
Lutron document 048561 assumes 2 full up and down cycles a day for Serena and Triathlon roller and honeycomb shades.
- Palladiom Wire-Free: 2 up and down cycles a day
- Triathlon Select roller shades: 1 cycle a day
- Serena and Triathlon wood blinds: 2 open and close tilts a day
