Factory reset
PTM 216B can be reset to its default settings by means of a factory reset.
This ensures that PTM 216B can be reset to a known configuration in case the PIN for the
NFC access has been lost or NFC access is not possible for other reasons
In order to execute such factory reset, the rocker(s) and the switch housing have to be
removed from the PTM 216B module. Then, all four button contacts (A0, A1, B0 and B1)
have to be pressed at the same time while the energy bow is pressed down.
The energy bow must then be held at the down position for at least 10 seconds before be-
ing released. The button contacts A0, A1, B0 and B1 can be released at any time after
pressing the energy bow down, i.e. it is no requirement to hold them as well for at least 10
seconds.
Upon detecting this input, PTM 216B will restore the default settings of the following items:
Static Source Address
Security
Key
and
Security

register
Both registers will be restored to the value of the factory-programmed security key

(EnOcean GmbH)
