Common questions
What torque and speed does the Sonesse 510S2 RTS RH deliver?
Somfy rates the Sonesse 510S2 RTS at 10 Nm of torque and 32 rpm. Part 1001805 is the RH version of this 120V motor, sized for heavier interior roller shades, solar screens and projection screens.
How does the RH model differ from the star head 510S2 RTS?
The motor itself matches part 1001807 in torque, speed and RTS radio. The difference is the head, so confirm your brackets accept the RH head before you order. Our store lists the LT50 Universal Motor Bracket (9410665) for this motor.
What is the smallest roller tube it fits?
Somfy lists a minimum tube inside diameter of 1.85 in (47 mm) for the Sonesse 510S2 RTS. Matching hardware in our store includes the LT50 2.5 in Round Crown and Drive Set (9012231) and the Octagonal LT50 70mm Crown and Drive Set (9012234).
Does this motor need power at the window?
Yes. It runs on 120V AC at 60 Hz, with a 1.67 A rated current and a 200 W draw while running. It uses a 3-wire SJTW cable. The built-in RTS receiver replaces control wiring, not the power feed.
Which remotes and wall switches work with it?
Any Somfy RTS transmitter works, including the Situo 1 and Situo 5 RTS Pure remotes (1870571, 1870575), the Telis 16 Channel RTS Pure remote (1811081) and DecoFlex RTS wall switches. The motor stores up to 12 transmitters, and Somfy lists an open-field range of 164.05 ft.
Can I control it from my phone, and is there a wired version?
Yes, through a Somfy TaHoma hub such as the TaHoma Switch (1871037). RTS is one-way radio, so the app sends commands but cannot report shade position. For a hardwired job, the Sonesse 510S2 RH 4-wire motor (1001810) delivers the same 10 Nm at 32 rpm.
