1. INTRODUCTION
The J4 io actuator is designed to drive the external venetian blind, types 1 & 2.
What is io-homecontrol®?
The J4 io uses io-homecontrol®, the new universal and secure wireless communica-
tion protocol, shared by the major manufacturers in the world of home automation.
io-homecontrol® enables all comfort and security equipment to intercommunicate and be
actuated via a single control point.
The exibility and perfect compatibility of the io-homecontrol® system provides support for
you as your needs evolve. You can start by automating roller shutters, external venetian
blinds and the front door, then equip the outside awnings, the gate and garage door or
garden lighting with the io-homecontrol® system.
These scalable items of equipment are still compatible with the existing system, thanks to
io-homecontrol® technology, which ensures their interoperability.

io-homecontrol® provides advanced and secure radio technology that is easy to install.
io-homecontrol® labelled products communicate with each other, improving comfort,
security and energy savings.
