Set address "5":
1. Enter addressing mode
2. Set 1- digit: Press button 5-times → LED flashes green per button press
Store address: press button until LED shines red
→ address is stored and displayed 1x for confirmation

7.3.3 Commissioning

The devices are especially designed for using the Climatix push-button configuration as
described in document A3975
parameterized by the local HMI, cf. page 28.
During commissioning check/set the following:
∂ Bus configuration (address, baudrate, transmission mode, and optionally
termination). The default address 255 allows to mount and power multiple actuators
at the same time without interfering with each other.
∂ Damper actuator parameters (opening direction, position limits, position adaptation
etc.) can be checked via the Modbus register.

The devices can be configured over bus if the pre-commissioning settings allow for a
connection between the Modbus master / programming tool and peripheral devices (i.e.
non-conflicting addresses and matching baudrate / transmission format).
∂ Full configuration over bus: If the address is unique per segment when powered up,
the device can be accessed by the Modbus master (or programming tool) and the
address and other parameters can then be set to the definitive values.
∂ Partial configuration over bus: If the address is not unique per segment when
powered up, each device must get a non-conflicting address before connecting it to
the bus, either by using the address input with push button (cf. page 29 ) or by
setting the address to 246 with push button press > 5s und < 10s (cf. page 28). After
addressing all devices, the remaining configuration can be done over the bus using
the default settings for baudrate (auto-baud) and transmission mode for the Modbus
master.
∂ Overwriting the bus configuration over bus uses a timeout. If „1 = Load" is not written
into Reg 768 within 30 seconds, all values are discarded.
Example: Table shows bus configuration registers before and after changing them over
bus.
