Common questions
How quiet is the Sonesse ULTRA 504A8 RTS?
Somfy rates it at 35 dB, quieter than the 45.1 dB Sonesse 506S2 RTS (1001809). That makes it a strong pick for bedrooms, offices and other interior rooms where shade noise matters.
What are the key specs of part 1134023?
Somfy rates it at 4 Nm and 25 rpm, with a 1.5 A rated current and 36 W draw while running. It fits tubes with a minimum inside diameter of 1.85 in and carries an IP 20 rating for interior use.
How do I power this motor?
It runs on 24V DC through a short two-wire fast connector lead. Somfy lists the 24V DC 1.67 Amp Plug-in Wall Mount Transformer (1822209) as its power supply.
Which bracket does it need?
The 504A8 has a square head, so it mounts with the Sonesse Ultra 50 DC Motor Bracket with Spring Ring (9020957). Star head LT50 brackets are made for other Sonesse 50 motors.
Which remotes and switches work with it?
Any Somfy RTS transmitter works, including the Situo 1 and Situo 5 RTS Pure remotes (1870571, 1870575), the Telis 1 Chronis RTS Timer (1805237) and DecoFlex RTS wall switches. The motor stores 12 channels, and Somfy rates range at 656.2 ft in open field.
Can I control it from my phone?
Yes, through the Somfy TaHoma Switch (1871037), which adds app control, schedules and voice assistant support. RTS is one-way radio, so the app sends commands but does not report shade position.
