KNX Motorised Rail
The motorised rail offers superior performance for heavy curtains or large glazed bays. The motor drives carriages along an aluminium rail.

Automation Scenarios
"Gentle Wake-up" Scenario
- • 7:00 am: sheers open to 50%

Coordination with Shutters
KNX integration lets you coordinate curtains and shutters for optimal light and temperature management:
- Summer: shutters closed + sheers = maximum solar protection
- Winter: shutters open + curtains = free solar gains

Frequently Asked Questions (FAQ)
How to motorise existing curtains with KNX?
Several solutions exist: connected rod motors, motorised rails or electric cord systems. The choice depends on the curtain type and window configuration.

Shutters offer full blackout and thermal insulation; curtains manage light and privacy. KNX coordinates both for optimal comfort.

What budget should I plan to motorise curtains with KNX?
Budget €400-800 per window for a full system (motor + rail + KNX actuator). Motorised rod systems are slightly cheaper (€300-600).
