Common questions
What is the Altus RTS 535A2 built for?
Part 1038168 is a 120V tubular motor with a built-in RTS radio receiver, sized for exterior solar screens, awnings and rolling shutters. Somfy also lists interior window coverings, projection screens and retractable insect screens among its applications.
What torque and speed does it deliver?
Somfy rates the 535A2 at 35 Nm of torque and 20 rpm. It draws 250 W while running and 0 W in standby, lists a noise level of 56 dB, and fits tubes with an inside diameter of 1.85 in or larger.
How is the motor powered and wired?
It runs on 120V/60Hz through a 3-conductor SJTW cable. The RTS receiver inside the motor replaces control wiring, so the motor needs a power feed and nothing more. Somfy rates the motor IP 44.
Which remotes and switches work with it?
Any Somfy RTS transmitter works, including Situo and Telis remotes, DecoFlex RTS wall switches and the Telis 1 Chronis RTS timer (1805237). Somfy lists 12 channels for this motor and rates RTS range at 656.2 ft in open field. Walls shorten that indoors.
Can I control it from my phone or a voice assistant?
Yes. Pair it with a Somfy TaHoma Switch (1871037) to run it from the app or by voice through a supported assistant. RTS is one-way radio, so the app sends commands but cannot report the screen's position.
Which crowns, drives and brackets does it take?
It uses standard LT50 star-head hardware. Matching parts in this store include the LT50 2.5 in Round Crown and Drive Set (9012231), the Octagonal LT50 70mm Crown and Drive Set (9012234), and the LT50 Star Head (9410651) or Universal (9410665) motor brackets.
