Sunea RTS CMO motor -- cassette and semi-cassette awning specialist with manual override
The Sunea RTS CMO motor is Somfy's dedicated motor for cassette, semi-cassette, and standard awnings. It automatically re-settles its limits as the fabric stretches over time, and includes a compact manual override crank so the awning can still be operated by hand if power is lost.
Benefits
- Automatically resets limits as awning fabric settles or stretches
- Compact manual override (CMO) crank keeps the awning usable during a power outage
- Soft-close function reduces stress on awning arms
- Electronic obstacle detection stops the motor if a blockage occurs
- Settings and programming are retained in the motor's memory

Common questions
What is the Sunea 535A2 CMO RTS motor built for?
Somfy built the Sunea RTS CMO for awnings, including cassette, semi-cassette and standard retractable models. CMO stands for compact manual override, a crank that lets you open or close the awning by hand if power is lost.
What torque and speed does it deliver?
Somfy rates part 1116321 at 35 Nm of torque and 20 rpm, with a 55 dB noise level. It carries an IP 44 protection rating and Somfy's 5-year warranty.
What tube and brackets does it fit?
Somfy lists a minimum tube inside diameter of 1.85 in. Mount it with the Motor Bracket for Sunea CMO RTS, US (9015802), and pair it with an LT50 crown and drive set such as the Octagonal LT50 70mm set (9012234).
How do I connect it to power?
It runs on 120V AC and ships with a short SJTW lead that ends in a Fast Connector. Add a 3-wire Fast Connector cable with plug, such as the 10.4 ft (9020791) or 24 ft (9020793) length, to reach an outlet.
What kind of limits does it use?
It uses electronic limits with a capacity of 250 turns. Settings stay in the motor's memory, and the motor re-settles its limits as the awning fabric stretches over time.
Which remotes work with it, and can I use an app?
Any Somfy RTS transmitter works, including the Telis 1 and Telis 4 RTS Patio remotes (1810643, 1810645) and the Telis Patio Multi Channel Soliris RTS remote (1811243). The motor stores up to 12 channels, with an open-field range of 656.2 ft. A TaHoma Switch (1871037) adds app control.
