Description

The purpose of this actuator is, to control Roto Rototronic skylight with shutters and/or sun blinds. It has 4 "channels". Each channel internally uses two relays: One for the open-action, and one for the close-action.

Of course you can also control your Roto Rototronic skylight with help of a standard switch-actuator. But then you don't have the possibility to "open the window 75%" or "close the shutter 80%". The firmware for DFF4.1 provides all this neat feature that you know from typical shutter/blinds actuators.

Hardware

This actuator consists of the following REG parts:

I2C address on application board:

A0: 1
A1: 0 
A2: 0

I2C address on frontend board:

A0: 0
A1: 0
A2: 0

Get a DIY kit

You are interested in this actuator? Great! This device is available as a DIY kit.

The kit includes all required parts with re-soldered SMD parts and pre-flashed controller board.

You only need:

  • soldering iron and solder
  • a screw driver
  • a sharp knife with a fine tip
  • a working KNX installation where you can connect the device to
  • ~2-3hrs to build it according to the build instructions linked on this page
  • a computer: Windows, Linux or MAC that is able to run KONNEKTING Suite plus a KNX IP Interface or an KNX IP Router.
  • for updating the firmware: A Mini USB cable (Not Micro-USB like on your smartphone. Mini USB is a big thicker as Micro USB)

Please write a mail to info@konnekting.de and refer to this page.

Build It

This actuator uses three PCBs, a bunch of SMD components as well as a lot of mechanical parts. As most users are not able to solder SMD, the PCBs are pre-soldered with all SMD components. Due to the big amount of parts, this actuator comes as a DIY kit: You have to solder non-SMD parts yourself and build up the device and finally flash the firmware with help of a USB connection.
