Information on the product | Function
KNX Data Secure
The device is KNX Data Secure capable. KNX Data Secure offers protection against
manipulation in building automation and can be configured in the ETS project. De-
tailed specialist knowledge is required. A device certificate, which is attached to the
device, is required for safe commissioning. During mounting, it is recommended to
remove the certificate from the device and to store it securely.
ETS versions
Planning, installation and commissioning of the device are carried out with the aid of
the ETS5, version 5.7.7 or higher or of the ETS6, version 6.0.3 or higher.
Operation
The operating elements (4 push-buttons) on the front panel of the device permit influ-
encing of the electronic outputs of the actuator through manual operation, even
without KNX bus voltage or in a non-programmed state (switch on and off / PWM).
This feature permits a fast function check of the connected actuators. Moreover, the
statuses of the outputs in case of bus voltage failure or bus voltage return and after
ETS programming can be set separately.
Mounting and electrical connection
The device electronics and the bus coupler are supplied from the bus voltage. The
valve outputs possess a separate connection for the supply of the connected actuat-
ors (AC 24 V or AC 230 V).
The device is designed for mounting on DIN rails in closed compact boxes or in dis-
tributors in fixed installations in dry interior rooms.
We recommend using electrothermal actuators of make Gira or, alternatively,
models of make Möhlenhoff (AA2004, AA4004) or Sauter (MTX). Always ob-
serve the technical data of the actuators and compare them with the technical
properties of the heating actuator.
