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
variable 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 actual 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 operating 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 pushbutton 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/shutter 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
current 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 floor heating system is installed.
Connecting 230 V signals or other external voltages to the inputs is not permitted.
