Control unit C4

The control unit C4 can be connected to other ZigBee components from our smart home product line to control lamps, shutters or other electrical consumers. So you can integrate more push-buttons, switches, motion sensors or twilight switches in your system

Note: The control unit is to be considered as an additional option, which provides more inputs. The components D1, S2, J1 and their rail-mount versions are already equiped with two inputs.

This component has 4 connectors for controls (inputs for switches or push-buttons). The connected push-buttons can be set up so that you can dim lights, turn on/off electrical consumers, control shutters or call up scenes, for example.

Invisible: The control unit C4 can be installed flush-mount behind every light switch or in a wall or ceiling – you do not have to renew your existing switches and power sockets. If you wish to install new switches, for aesthetic reasons for example, you can freely choose the manufacturer and program. However, unconventional switches, which are used in bus systems (KNX/EIB) for example, are not suitable. The compact design simplifies installation.

The wireless components of ubisys’ smart home system are based on the international standards IEEE 802.15.4 and ZigBee. This guarantees a long-term availability of components a protection of your investments.

Due to the resilient and innovative radio controlled technology there are no special skills needed when installed. This solution not only makes it ideal for new buildings but also for redevelopments and renovations. Additional components can be added and perfectly integrated into your smart home by and by. This leaves the decision when and how extensively you want to expand your system entirely up to you.

And with the Over-the-Air (OTA) firmware upgrade this component — as well as all other smart home components — will always stay up to date. This makes you well prepared for the future „Smart Grid”.
