Room temperature controller
There are 12 controllers integrated into the device's software that can be used for in-
dividual room temperature control. This allows the temperature to be set in up to 12
rooms or room areas to specified setpoints through independent control processes.
The command value outputs of these controllers can be linked to the electronic valve
outputs of the actuator, meaning that temperature control and valve activation can
take place using just one bus device, if required. The use of external room temperat-
ure controllers (e.g. push-button sensors with RTC) is thus not absolutely essential,
but is possible as the valve outputs can also be activated individually via the KNX.
The integrated controllers can also transmit command value telegrams to the KNX
and thus activate other heating actuators or fan coil actuators.
The integrated controllers of the device always work as the main controller. All the
controller functions (e.g. setpoint temperature specification, operating mode
switchover, switchover of the operating mode) are controlled via KNX communication
objects (object controller without its own operating elements), meaning that controller
operation is possible via controller extensions or visualisations. The room temperat-
ure is made available to the integrated controllers via separate communication ob-
jects.
Channel configuration
10.1
To simplify project design, all room temperature controllers can be activated or deac-
tivated individually in the ETS. Parameters and communication objects of the deactiv-
ated channels are hidden.
To simplify further, the room temperature controllers can be assigned to the same
parameters and thus configured identically. The parameter "Parameterisation" stipu-
lates whether every room temperature controller of the device can be configured indi-
vidually or whether the parameters of room temperature controller 1 are to be ap-
plied.
With the setting "like RTC 1", the parameter pages in the ETS are reduced. The vis-
ible parameters of the first room temperature controller are then automatically also
used on this room temperature controller. Only the communication objects can then
be configured separately for the controllers. This setting should be selected, for ex-
ample, if all room temperature controllers behave identically and should only be activ-
ated by different group addresses (e.g. in office blocks or in hotel rooms).
In the parameter setting "individually", each room temperature controller possesses
its own parameter pages in the ETS.
