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.

This actuator consists of the following REG parts:

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.
