Module 1 of 4

Read the old motor

What to copy from the failed motor before you order. After this module you can order a replacement from the label.

2 lessons, then a scenario check.

Read the old motor

Part number and model code

Find the part number and model code on the motor. The model code carries the torque: 506S2 is a 6 Nm Sonesse 50.

On the jobPhotograph the label before the motor comes out of the tube.

COPY FROM THE OLD MOTORPart numbere.g. 1001809Model codee.g. 506S2, 6 NmControlRTS, Zigbee, wired, RS485Headstar, round or square

Read the old motor

Same part, same fit

Ordering the same part number gives the same torque, speed, head and tube fit. The Sonesse 506S2 RTS 1001809 is 6 Nm at 32 rpm with a star head.

ExampleA label reading 1001809 means you order 1001809.

Somfy Sonesse 506S2 RTS 120V Motor (1001809)
Sonesse 506S2 RTS 120V (1001809)

Check yourself

The label on a failed motor reads 506S2. What torque does that tell you?

Module 2 of 4

Match the control type

Why the protocol must match the remotes and system already on site. After this module you will not order a motor the house cannot talk to.

2 lessons, then a scenario check.

Match the control type

Same lift, different control

Somfy builds the 506S2 as RTS (1001809), RS485 (1002286) and 4-wire (1001814). All three give 6 Nm at 32 rpm. Only one matches the controls on site.

Watch forAn RTS motor will not answer a wall switch wired for a 4-wire motor.

Match the control type

Keep the remote

An RTS replacement pairs to the RTS remote the owner already has.

On the jobAsk for every remote and wall switch that ran the old shade.

Check yourself

The old motor was a 506S2 4-wire on a wall switch. The client orders 1001809. What is wrong?

Module 3 of 4

Match the fit

The mechanical points that decide if the new motor drops into the tube. After this module you can confirm fit before the old motor comes out.

3 lessons, then a scenario check.

Match the fit

Head type is per part

Somfy lists head type per part number: the 506S2 RTS has a star head, the Sonesse 40 404S2 a round head and the ULTRA 504A8 a square head.

Watch forA different head means a different bracket. Check before you swap families.

Match the fit

The bracket holds the head

Each head type sits in its own bracket. An LT50 star head motor, for example, sits in a star head bracket such as 9410651.

ExampleSame part number, same head: the old bracket stays on the wall.

Match the fit

Crown and drive

The crown and drive grip the tube and belong to the motor family. An LT50 on a 70 mm octagonal tube takes a set such as 9012234.

On the jobMove the crown and drive across only when the new motor is the same family.

Check yourself

A client wants to swap a failed 506S2 for a Sonesse 40 404S2 to save money. What changes?

Module 4 of 4

Program the new motor

How a new RTS motor arrives and the order to set it up. After this module the shade runs on its old remote.

2 lessons, then a scenario check.

Program the new motor

It ships in factory mode

Somfy ships RTS motors in factory mode: no limits and no paired controls. Power only the motor you are programming.

ExampleUnplug the other shades on the circuit while you set up the replacement.

Program the new motor

Setup order

Hold UP and DOWN until a jog, check direction with DOWN, set the limits, then press PROG on the remote to finish.

On the jobAdd the owner's other remotes and wall switches once the first remote works.

A replacement RTS motor does nothing when the old remote is pressed. Why?
