01 — At a glance

What sets this motor apart.

Somfy designed this tubular motor for vertical exterior screens, including ZIP screens with side tracks. It delivers 25 newton-metres at 20 rpm and runs on 120 volts.

It detects obstacles to protect the fabric and the patio furniture, and automatically adjusts the fabric tension, a function specific to ZIP screens. Its electronic limit switch ensures precise stops.

It measures 24.13 in, like the 510A2. It is the most powerful motor in the exterior lineup in this short format.

  • 25 newton-metres at 20 rpm

    More than double the 510A2, in the same length.

  • The only motor for our Zip Track

    Our Zip Track shades work only with the Maestria+ 50 on 120 V, no exceptions. Only the strength is chosen.

  • Obstacle detection

    The motor stops if it meets an obstacle, protecting the fabric and the patio furniture.

  • Fabric kept taut

    It automatically adjusts the fabric tension: a function specific to ZIP screens.

  • Precise settings

    Electronic limit switch: the bottom bar stops at the same spot every cycle.

  • RTS compatible

    Works with all Somfy RTS controls and the TaHoma box.

  • Short format

    24.13 in (613 mm): the most powerful of the short models.

03 — Which blinds

The right blind for this motor.

Depends on the screen

Blind width

The minimum width depends on the screen, not just the motor.

The motor measures 24.13 in (613 mm). The minimum fabric width matches that length, plus the end fittings and the screen's housing. Somfy does not publish a minimum width for this motor.

Le Gars des Stores confirms the allowable width at measurement, based on the housing and tube selected.

What to consider before choosing

  • A 120 V power supply must be planned outdoors, near the housing or as a direct connection. An electrician determines the circuit based on the actual load and the applicable code. This is the main difference from battery-powered interior motors.
  • This motor runs on RTS: control is one-way. The remote or TaHoma sends the command without receiving the actual position of the fabric.
  • Torque is chosen according to the size of the screen and the weight of the fabric. Le Gars des Stores confirms the right model at measurement.
  • For large screens, the 535A2 and 550R2 go up to 35 and 50 newton-metres, but measure 26.89 in. On a narrow opening, that difference in length matters.

05 — Frequently asked questions

What customers ask.

Which screen is the Maestria+ 50 RTS 525A2 suited to?

A medium-size exterior screen, or a fabric heavier than the 510A2 can handle. Torque is chosen according to the size of the screen and the weight of the fabric; Le Gars des Stores confirms it at measurement.

Why choose the 525A2 over the 535A2?

For its length. The 525A2 measures 24.13 in, compared with 26.89 in for the 535A2. When the opening is narrow and 25 newton-metres are enough, the short format is preferable.

Do I need an outdoor electrical outlet?

Yes. The system needs an outdoor 120 V power supply near the housing, or a direct connection, depending on the motor. The location is confirmed at the measuring visit. An electrician determines the circuit and how many motors it can power, based on the actual load and the applicable code. Somfy also offers 24-foot extension cables, so the power can be much farther from the shade.

Which controls does it work with?

With all Somfy RTS controls: Situo or Telis remotes, and the TaHoma box for the app, schedules and voice control. RTS sends the command without feedback: the remote does not show the position of the fabric.

How does the motor keep the fabric taut?

Somfy gave it an automatic adjustment specific to ZIP screens: the motor keeps the fabric taut in its side tracks, with no adjustment on your part.

Do you install in Montreal, Sherbrooke and the Eastern Townships?

Yes. Le Gars des Stores serves the West Island and Montreal, Vaudreuil-Dorion, the South Shore, the North Shore, western Laval and the Eastern Townships (Sherbrooke, Magog); elsewhere, depending on the project. We handle measuring, made-to-measure ordering, installation and programming.
