Opening tilt-and-turn windows automatically: tilt actuator and locking

Updated: 07.11.2026

In brief: A tilt-and-turn window can be tilted electrically once two things are solved: the hardware must be unlocked, and a tilt actuator pushes the sash open. Either the window stays permanently in the tilt position, or a Locking drive takes care of unlocking. The force is low – the stroke is limited by the tilt hardware.

Why is the hardware the real hurdle?

On a tilt-and-turn window, the handle moves the locking all around via a gearbox. A chain actuator alone cannot open a locked sash. There are therefore two ways:

1. Handle in tilt position: The sash stands in the tilt hardware; the Chain actuator opens and closes it. Simple and inexpensive, but the window is not locked when closed.
2. With a locking actuator: An actuator such as the VS-VA 600 operates the fitting gearbox. The control unit unlocks first, then the tilt actuator opens; when closing, the other way round. This way the window is locked again when closed.

Which stroke and which force?

Many tilt fittings only allow 100 to 180 mm opening; beyond that the actuator pushes against the safety stay. The force is small: a sash measuring 1.2 × 1.0 m with triple glazing needs only around 31 N at 150 mm stroke, around 40 N with 30 % reserve. A chain actuator with 250 N is therefore more than enough, see also Bottom-hung window with triple glazing.

What to look out for

• Whether the turn function for cleaning is retained depends on the hardware and installation. Clarify this in advance.
• Actuator and bracket need space on the frame; with narrow profiles the concealed VS-CKA 300 is an option.
• Windows within reach: pay attention to the closing edges and anti-trap protection.
• With a control unit and Rain sensor the window closes automatically when it rains.

Frequently asked questions

Can every tilt-and-turn window be retrofitted?

Most can, if there is space for actuator and bracket. For the version with a locking actuator, the hardware must be suitable. Send us photos of the hardware and profile.

Is a 230 V actuator enough?

For a single window in the tilt position, yes, with a ventilation switch. If a locking actuator is to run as well or sensors are to control the window, we recommend 24 V with a control unit.
