- J4 IO engine

The J4 io Protect drive is a modern drive designed for all types of facade blinds. Has a built-in radio receiver. J4 io Protect operates on io-homecontrol® technology, which provides feedback on the exact position of the drive.

Facade blinds with Somfy drives allow you to smoothly manage the amount of light that enters the interior by rotating the slats. Thanks to the icing and obstacle detection functions, the J4 io Protect protects the shields against damage, thus extending their lifetime.

Convenient blinds control options at any time: local control with Situo Variation io and Nina io remote controls and via the internet from the TaHoma® Premium and Connexoon Window io smart home control panel applications.

The drive is also distinguished by the automatic adjustment of the upper end position - J4 io Protect remembers the settings (position of the lower strip in relation to the diaphragm) and automatically restores them after 50 cycles, and therefore in case of unwanted configuration changes - the drive will adjust itself automatically.
