Functions:
Room temperature controller functions:
The room temperature controller can be used to control the temperature of individual rooms.
Depending on the control option of the current temperature
-setpoint and the room temperature, an actuating
v
ariable for the heating or cooling control system can be transmitted to the KNX / EIB.
The room temperature can optionally be sensed by the internal temperature sensor or by an external
temperature sensor connected to the terminal strip of the push
-button interface.
As a supplement to basic heating or cooling, an additional stage can also be activated. The temperature
setpoint difference between the basic and the additional stage can be set in a parameter. For larger
deviations between the setpoint and act
ual temperature value, the room can therefore be heated up or cooled
down more quickly by switching on the additional stage. The basic and the additional stage can have different
control algorithms assigned to them.
The controller can operate in 5 operati
ng modes (comfort, standby, night, frost/ heat protection and controller
disable) each having their own temperature setpoints for the heating mode or cooling mode. For the heating
and cooling functions continuous
-action or switching PI or switching 2-point control characteristics can be
selected.
Push
-button interface functions:
The pushbutton interface has four independent channels which
– depending on parameterization – can work
as inputs or alternatively as outputs (channels 1 or 2 only). Thus, the pus
hbutton interface can read up to 4
pushbutton/switching states with a common reference potential via its potential
-free inputs and transmit the
corresponding telegrams to the KNX / EIB.
The telegrams can be telegrams for switching or dimming, for
blind/sh
utter control or for value transmitter applications (dimming value transmitter, light-scene extension,
temperature or
brightness value transmitter).
As independent outputs, channels 1 and 2 can alternatively control up to 2 LEDs. To increase the output
cur
rent capability (cf. technical data), these channels can also be connected in parallel, if they have the same
parameterization. The outputs are short
-circuit-proof and protected against overload and polarity reversal.
Channel 4 can optionally also be used
as an external sensor for the room temperature controller or as a
temperature limiter when a radiant flo
or heating system is installed.
Connecting 230 V signals or other external voltages to the inputs is not permitted.

Object controller
The continuous
-action controller is also available without control elements. This variant is called object
controller. This means that the object controller has no status LEDs (B
- I) no presence key (A) and no control
knob (J). The room temperature controller and pushbutton interface functions are however the same as in the
continuous
-action controller. The room temperature controller function of the object controller is operated
exclusively by means of telegrams via the bus.
(The object controller has other article nos. and similar ETS search paths.)

Independent of the setting of the parameter "Temperature sensing" (internal sensor, external sensor or
internal and external sensor), the function shows the non-adjusted (and non-weighted) actual value of the
internal temperature sensor.
1: Optionally, the "T" flags can be set for the operating mode switch-over. Once the flags are set, the object
values which have changed according to the newly set operating mode will be actively transmitted to the
bus.
2: This object is only visible in mixed operation "heating and cooling" or "basic / additional heating / cooling".
The "T" flag is set for automatic heating / cooling switch-over.
3: This object is only visible when additional stage is activated.
