The Single Rocker (EWSSZ) / Double Rocker (EWSDZ) Wall Switches in the European 55 x 55 form factor are simple to install and use energy harvesting technology to communicate wirelessly with other devices supporting the ZigBee Green Power (ZGP) standard.
EWSSZ and EWSDZ use the PTM 215ZE pushbutton transmitter module from EnOcean and therefore they are fully self-powered and never require batteries. The simple act of pressing the rocker generates enough energy to send wireless telegrams to other devices. EWSSZ and EWSDZ wall switches therefore provide convenient control of lighting, temperature and miscellaneous electric loads.
The enclosed switch frame can be replaced by frames of the following design programs: BERKER S1, B1, B3, B7 Glas, or GIRA Standard55, E2, Event, Esprit or JUNG A500, Aplus or MERTEN M-Smart, M-Arc, M-Plan.
