Somfy sizes the Glydea ULTRA line by the weight of the drapery it pulls. The ULTRA 35 carries panels up to 77 lb (35 kg), which covers most residential pinch pleat and RippleFold treatments plus a fair share of light commercial work. Fabricators who miss this number find out on site, when a loaded master carrier crawls across a long run instead of gliding.
This listing covers the motor head on its own, sold without a track. Somfy's catalog name for part 1246116 is Glydea ULTRA 35 Motor RTS with 10 ft Plug. Shops building a fresh track order rail, belt, carriers and brackets alongside it. Shops replacing a failed head on an existing Glydea track order the motor by itself and reuse the rest.
Panels the ULTRA 35 pulls
The ULTRA 35 drives horizontal traversing draperies on a Somfy Glydea track. Think sheers and lined panels in a living room, hotel guest rooms, conference rooms, and patient rooms where a quiet motor matters more than raw speed. Somfy rates the motor at 38 dB, which puts it among the quietest drapery drives the company builds.
The motor handles pinch pleat and RippleFold headings, and it works with Accordia styling. Center opening and one way draw both run on the same head, with the arm kit and master carrier setting the draw direction. At 0.6 Nm and 105 rpm, the ULTRA 35 moves a panel across a wide opening in seconds while soft start and soft stop keep the fabric from swinging at each end.
Touch Motion gives a second way in. Pull the leading edge of the panel by hand and the motor picks up the travel from there, which guests and staff reach for before they find a remote.

Track parts that finish the job
A Glydea motor head reaches the ceiling through a bracket, and the Somfy Glydea One Touch Ceiling Bracket (1780907) clips the rail into place without threading hardware through the track. Order one bracket per support point along the run, and add supports as panel weight climbs toward the 77 lb ceiling.
At the far end of the rail, the Somfy Glydea Drive Pulley (1780945) returns the belt and holds its tension. A worn pulley shows itself as belt chatter and a master carrier that drifts past its stop, so keep a spare on the truck for service calls.
The Somfy Glydea Heavy Duty Master Carrier (1781344) takes the pull from the belt and hands it to the leading panel. Heavier fabrics, blackout linings and wide single draws all load this part harder than a sheer does, and the heavy duty version holds its shape under that load.
Behind the master carrier, runners carry the rest of the fabric. Somfy RippleFold 100% carriers, 6 per ft (1780902) set the fold depth for a standard RippleFold look. Count the carriers off the finished track length before ordering, since fold percentage changes the count per foot.
RTS control and TaHoma
The ULTRA 35 RTS carries its radio receiver inside the head. Installers pair a handheld or wall transmitter to the motor and skip the separate receiver box that a wired motor needs. Somfy publishes 12 channels and a 656.2 ft open field range on 433.420 MHz, which reaches across a floor plate without line of sight.
Adding a TaHoma hub brings the same motor onto a phone, a tablet and a voice assistant. Scenes let one command close every drapery on a west elevation at sunset, and schedules take over on days nobody is in the building. Somfy designed RTS as a one way protocol, so a TaHoma scene sends the command and the motor runs it.
Power, placement and cable length
Somfy ships part 1246116 with a 9.84 ft cord and a plug, which reaches a receptacle above a ceiling line or inside a pocket in most rooms. Electricians who prefer a hardwired finish still need the outlet or junction box within that cable run, since the cord attaches at the motor end.
The head draws 30 W while it runs and 0.27 W at rest, a small enough standby load that a floor of drapery motors stays off the radar of a building energy budget. Rated current sits at 0.54 A. The 7 minute thermal cutout protects the motor during repeated cycling, and a head that shuts down mid demo has told you the cycle count was too high, not that the part failed.
Mount the motor at the end of the rail the drapery stacks toward, with the head inside the pocket or behind a fascia. Its 13.7 in length and 2.09 in height set the minimum pocket depth, so check those two numbers against the millwork drawing before the carpenter builds the box.
Limit setting and manual operation
The ULTRA 35 uses electronic limits, and a fine adjustment lets an installer bring the closed position to the exact center of a pair of panels. Somfy's RTS Pocket Programming Guide walks the key sequence for pairing a transmitter and trimming each end point. Keep that guide on hand for the second and third motor on a job, when memory of the first one has faded.
Power loss does not lock the drapery in place. Staff can draw the panel by hand, and the motor picks the limits back up once power returns. That single behavior answers most of the questions a facilities team raises before they approve a motorized drapery package.
One habit saves callbacks: set limits with the finished panel hung, not with a bare carrier. Fabric weight changes where the master carrier settles, and a limit set on an empty track leaves a gap at the center overlap.
Frequently asked questions
How much drapery weight does the Glydea ULTRA 35 carry?
Somfy rates the ULTRA 35 for drapery up to 77 lb (35 kg). That figure covers the full panel assembly, including lining and any weighted hem. Jobs that land near the top of the range deserve extra ceiling supports along the rail. Heavier packages move up to the larger Glydea ULTRA head instead.
Does the Glydea ULTRA 35 RTS need a separate RTS receiver?
No. Somfy builds the RTS receiver into the motor head on part 1246116. Pair a Somfy RTS handheld or wall transmitter straight to the motor, with no receiver box and no control wiring between them. A TaHoma hub joins the same motor later for app and voice control.
How far does the RTS signal reach?
Somfy publishes 656.2 ft in open field on 433.420 MHz, across 12 channels. Walls, metal studs and elevator shafts cut into that figure inside a building. For long runs through a commercial floor plate, plan transmitter placement during rough in rather than after the draperies hang.
Does the motor ship with a power cord?
Yes. Somfy names this part Glydea ULTRA 35 Motor RTS with 10 ft Plug and publishes a 9.84 ft cable length. Position the receptacle or junction box within that reach of the motor end of the rail. Confirm the cord and connector against the motor you receive before the electrician sets the outlet.
The Somfy Glydea ULTRA 35 RTS Drapery Motor (1246116) ships as the motor head, ready to drop onto a new Glydea track or replace a head on an existing one. Pair it with a ceiling bracket, a drive pulley, a heavy duty master carrier and the carrier count your fold percentage calls for, and the track leaves the shop as a complete assembly.
