Common questions

What is the 525A2 RTS CMO motor used for?

Part 1043426 is a 120V LT50 tubular motor for awnings and rolling shutters. It combines a built-in RTS radio receiver with a Compact Manual Override (CMO) head. Somfy rates it at 25 Nm and 20 rpm.

Can I operate it during a power outage?

Yes. The CMO head accepts a hand crank, so you can move the awning or shutter by hand when the power is out. The CMO Awning Override Shaft, 100mm with Geiger Eye (9707287), links the crank to the motor.

What power and wiring does it need?

It runs on 120V/60Hz, within 108 V to 126 V, with a rated current of 1.6 A and 180 W in operation. The removable 12.3 ft, 3-wire SJTW cable has stripped ends. Standby draw is 0 W.

Which remotes and wall switches work with it?

Any Somfy RTS transmitter pairs with it, including the Telis 1 Channel RTS Patio Remote (1810643), the Telis 4 RTS Multi-Channel Patio Remote (1810645), Situo RTS Pure remotes (1870571, 1870575) and the DecoFlex 5 Channel RTS Wall Switch (1810813). The motor stores up to 12 transmitters.

How are the limits set, and what conditions can it handle?

The motor uses electronic limits with a capacity of 34 turns. Somfy rates it at IP 44 and lists an operating range of -13 °F to 158 °F. The compatible parts on this page include the Octagonal LT50 70mm Crown and Drive Set (9012234).

Can I add app control or a stronger motor?

Yes. A Somfy TaHoma Switch (1871037) adds app control, schedules and voice control. For larger awnings, the 535A2 RTS CMO 120V Motor (1047306) delivers 35 Nm at the same 20 rpm with the same CMO head.
