Slat Actuation

Why take an interest in SUNDIY slat actuation accessories?

Slat actuation systems are the backbone of a bioclimatic pergola or an adjustable slat privacy screen: without them, it is impossible to enjoy light control, natural ventilation, or protection from rain. Whether you are a DIY enthusiast, self-builder, craftsman, architect, or construction professional, choosing the right orientation system directly impacts the durability, ease of use, and added value of your structure.

What are the main types of actuation systems available?

Manual or motorised actuation: what’s the difference?**

SUNDIY offers five product families:

• Electric motorisation: a 24 V linear actuator (SMART range) or a 1200 N actuator (PRO range) that controls multiple bays via a simple remote control or SOMFY® home automation.
• Blade Driver: stainless steel base + removable control rod, ideal for occasional and cost-effective manual operation.
• Blade Runner: geared dial winch. One START KIT controls 1 bay; add ADDITIONAL KITS as required.
• Blade Click: aluminium locking handle that rotates and locks vertical slats in position.
• Blade Locker: 5-position locking device preventing wind-driven opening of claustra or shutter slats.

How do I choose the right actuation accessory for my project?

[**Which technical criteria should I check?**}

• 1. Slat compatibility: thickness, height, material (wood or aluminium).
• 2. Span and load: number of bays, total surface area, wind resistance.
• 3. Power supply: 230 V mains, 24 V low voltage, or solar autonomy (SMART + PV kit).
• 4. Environment: coastal areas, mountains, public buildings requiring manual emergency operation.
• 5. Overall budget: purchase price, ease of installation, maintenance.

*Did you know?* The PRO range withstands wind speeds above 240 km/h, making it ideal for coastal or high-altitude installations.

Which manual system should I choose: Blade Driver or Blade Runner?

Blade Driver key advantages**

• Simplicity: one base per bay + a single control rod for the entire structure.
• Low cost: from €16 excl. VAT per base and €20 excl. VAT per rod.
• No electrical maintenance.

Blade Runner benefits**

• Fine adjustment thanks to the geared winch.
• Modular extension: add one ADDITIONAL KIT for each extra bay.
• Comfort: reduced effort, operation possible from a side post.

How do I install a SUNDIY manual actuation system?

What are the key steps to follow?**

1. Marking the rotation axes on your slats.
2. Ø12 mm drilling for the stainless steel shaft (Blade Driver) or sprocket installation (Blade Runner).
3. Fixing the base or winch using A2/A4 stainless steel screws.
4. Assembly of link rods (Blade Runner) or insertion of the control rod (Blade Driver).
5. Testing rotation over 90 ° to 110 ° depending on the slat profile.

An experienced DIYer can complete these steps in < 2 hours per bay, excluding finishing work.

How do I install SMART or PRO motorisation?

Is the electrical installation complex?**

No: the SMART motorisation integrates an 80 W power supply inside its IP65 housing. Simply:

1. Fix the actuator under the drive slat on the axis protected by an aluminium cover.
2. Connect the TVSLIM cable to the control unit.
3. Wire the control unit to the 230 V mains via a 30 mA residual-current circuit breaker.
4. Program the multifunction remote control to open/close and set a 45 ° position.

The PRO motorisation additionally offers:

• Rain/wind/temperature inputs for automatic closing;
• Smartphone control via IO-HomeControl or Zigbee gateway;
• SOMFY TaHoma compatibility for home automation scenarios.

Can I add a solar kit?

Yes. A compact 20 W photovoltaic panel recharges a 12 Ah LiFePO4 battery, allowing 100 cycles of operation even in overcast conditions. Ideal for off-grid installations (garden shelters, chalets, van workshops).

How can I automate slat orientation based on weather conditions?

Which sensor should I choose: rain, wind, or temperature?**

The RAIN106WTS01HK kit (3-in-1 sensor) communicates via 868 MHz radio with the PRO control unit.

• Rain: automatic closing from 0.3 mm/min.
• Wind: slats set to 0 ° when gusts exceed 50 km/h.
• Temperature: partial opening to 30 ° for indoor over-ventilation.

How do I maintain my actuation accessories?

Which annual maintenance actions are recommended?**

• Cleaning with soapy water and a nylon brush (no pressure washer).
• Lubrication of stainless steel pivots using marine grease (coastal areas).
• Torque check of screws after 500 cycles.
• Firmware update (PRO motorisation) via the mobile app.

Regular maintenance extends service life beyond 15 years and preserves the 5-year SUNDIY warranty.

What budget should I plan for and what ROI can I expect?
