Service
1. Press the "Address" button until the green "Power" LED is no longer illuminated. LED flashes
in accordance with the previously set address.
2. Set the address by pressing the "Address" button the corresponding number of times (1...16).
3. The green LED flashes in accordance with the address that has been entered (...16). If the
address is not correct, then this can be reset in accordance with Step 2.
4. Confirm the address setting by pressing the green "Adaptation" button.
If no confirmation occurs for 60 seconds, then the address procedure is ended. Any address
change that has already been started will be discarded.
The resulting BACnet MS/TP and Modbus RTU address is made up of the set basic address plus
the short address (e.g. 100+7=107).
The actuator can be configured by ZTH EU via the service socket.
For an extended configuration the PC tool can be connected.
