As-Delivered State - Gira KNX 2139 00 Product Documentation

As-delivered state

12 As-delivered state
In the as-delivered state, the actuator is passive, i.e. no telegrams are transmitted to
the bus. The outputs can, however, be activated by manual operation on the device if
the bus voltage and the valve voltage supply are on. In manual operation, no feed-
back telegrams are sent to the bus. Other functions of the actuator, such as the room
temperature controllers, are deactivated.
The device can be programmed and put into operation via the ETS. The physical ad-
dress is preset to 15.15.255
Furthermore, the device has been configured at the factory with the following charac-
teristics (all valve outputs)...
– Valve direction of action: deenergised closed
– Pulse width modulation on "Open valve": 50%
– Cycle time: 20 minutes
– Behaviour in case of bus voltage failure: All the valve outputs switch OFF.
– Behaviour after bus voltage return: All valve outputs switch OFF.
