Factory Reset

PTM 215B can be reset to its default settings by means of a factory reset.

This ensures that PTM 215B 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 215B 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 215B will restore the default settings of the following items:

Source Address

Security Key and Security Key Write register

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

NFC PIN Code

After such factory reset, Source Address and Security Key will again match the content of

the DMC code on the unit label as described in chapter 3.3.

In addition, PTM 215B will reset the following register:

Configuration register (to 0x00)
