The thermostat's control parameters can be set to ensure optimum performance of
the entire system (refer to basic documentation CE1P3174).
The parameters can be adjusted using
-
Local HMI
-
Synco ACS
-
ETS4/5
For commissioning via local HMI, refer to user manual A6V11272225 for setting the
passwords.
· Only heating sequence is available.
· Recalibrate the temperature sensor if the room temperature displayed on the
thermostat does not match the room temperature measured (after min. 1 hour of
operation). To do this, change parameter P05.

· We recommend to review heating setpoint and their range limitation via
parameters P08...P11. If necessary, adjust them to achieve maximum comfort
and save energy.
The programming mode helps identify the thermostat in the KNX network during
commissioning.
Touch and hold
for more than 5 seconds to activate programming mode, which
is indicated on the display with Pr09. Programming mode remains active until
thermostat identification is complete.
Assign device address (P81) via HMI, ACS or ETS4/5.
With device address set to 255, the communication is deactivated (no exchange of
process data).
Use ETS4/5 to assign the KNX group addresses of the RDF communication
objects.
Each device has a unique KNX serial number inside the front panel. An additional
sticker with the same KNX serial number is enclosed in the packaging box. This
sticker is intended for installers for documentation purposes.
The RDF880KN... room thermostats support communications as per KNX
specification.
-
S-mode:
Standard mode; engineering using group addresses.
-
LTE mode: Logical Tag Extended mode, for easy engineering, used in
conjunction with Synco.
· This mode corresponds to KNX communications. Connections are established
via ETS by assigning communication objects to group addresses.
· LTE mode is specifically designed to simplify engineering. In contrast to S-mode,
there is no need to create individual connections (group addresses) in the tool.
The devices establish connections autonomously.
