GENERAL DESCRIPTION
The radio transmitter device PTM 215ZGP from EnOcean enables the implementation of
wireless remote controls without batteries. Power is provided by a built-in electro-dynamic
power generator. The PTM 215ZGP device transmits data based on the 2.4GHz ZigBee
Green Power standard.
The outer appearance of PTM 215ZGP is shown on the picture below.

Basic Functionality
PTM 215ZGP devices contain an electro-dynamic energy transducer which is actuated by a
bow (1). This bow is pushed by an appropriate push button, switch rocker or a similar con-
struction mounted onto the device. An internal spring will release the energy bow as soon
as it is not pushed down anymore.
When the energy bow is pushed down, electrical energy is created and a ZigBee Green
Power radio telegram is transmitted. Releasing the energy bow similarly generates energy
which is used to transmit a different ZigBee Green Power radio telegram. It is therefore
possible to distinguish between radio telegrams sent when the energy bar was pushed and
radio telegrams sent when the energy bar was released.
By identifying these different telegrams types and measuring the time between pushing
and releasing of the energy bar, it is possible to distinguish between “Long” and “Short”
push button presses. This enables simple implementation of applications such as dimming
control or blinds control including slat action.
The PTM 215ZGP radio telegram identifies the status (pressed or not pressed) of the four
contact nipples (2) when the energy bow was pushed or released. This enables the imple-
mentation of up to two switch rockers or up to four push buttons.
