Menu item "Authorizations" is used to specify whether a user with installer
authorization is required for the reconfiguration of the actuator.
In addition, you can nevertheless assign users with read rights the authorization to
switch this actuator.

The −/+ buttons can be used to specify by how
many degrees the temperature is to be reduced
to when ECO mode is activated.
Manual increase/reduction of the temperature
value via the -/+ buttons to adjust a permanent
temperature offset.
If the ECO mode is deactivated by a movement
detector, the switch-off delay can be specified
here when the ECO mode is to be re-activated
after the room is exited.
The following selection options are available for
the temperature reading.
Internal for regulating:
■
– Use of the internal temperature sensor of
the device for reading and regulating the
room temperature.
External for regulating:
■
– Use of an external temperature sensor for
reading and regulating the floor
temperature. For this the external
temperature sensor must be laid in the
screed.
Internal and external for regulating:
■
– Use of the internal and an external
temperature sensor for reading and
regulating the room temperature. Both
measured values are used to create an
average value. For this the external
temperature sensor must be installed
behind a ventilated cover plate (e.g. 6541-
xx).
Internal for regulating and external for
■
limiting:
– Use of the internal and an external
temperature sensor for reading
temperature. The temperature is regulated
via the internal temperature sensor. The
external temperature sensor serves for
limiting the temperature, generally the floor
temperature (floor heating). As soon as the
temperature measured on the external
temperature sensor exceeds the set
temperature, the relay is switched off.
Heating stops.
Manual increase/reduction of the temperature
value of the external sensor, to adjust a
permanent temperature offset.
Fixing the maximum admissible temperature that
is allowed to be measured by the external
temperature sensor before the relay for the
heating is switched off. The upper temperature
limit is used, for example, to ensure that the floor
temperature does not get too warm and cause
damage to the floor covering.
