1 Safety instructions
Electrical devices may be mounted and connected only by electrically skilled
persons.
Serious injuries, fire or property damage are possible. Please read and follow the
manual fully.
Danger of electric shock at the KNX installation. Do not connect any external voltage
to the inputs. The device can become damaged, and the SELV potential on the KNX
bus line will no longer be available.
This manual is an integral part of the product, and must remain with the customer.

The function of the device depends on the software. Detailed information on the soft-
ware version and the respective scope of functions as well as the software itself can
be obtained from the manufacturer´s product database.
The device is planned, installed and commissioned with the aid of KNX-certified soft-
ware. Full functionality with KNX commissioning software version ETS3.0d onwards.
Updated versions of the product database, technical descriptions, conversion pro-
grams and other auxiliary programs are available on our website.
4 Intended use
– Single-room temperature control in KNX installations
– Mounting in appliance box with dimensions according to DIN 49073
5 Product characteristics
– Measurement of the room temperature and comparison with the setpoint tem-
perature
– Setpoint specification by selecting the operating mode
– Operating modes: comfort, standby, night operation, frost/heat protection
– Heating and cooling mode
– Heating and cooling with basic and additional level
– Operation solely via the bus
– Push-button interface with four inputs or two outputs and two inputs, e.g. for
window contacts, push-buttons, LEDs, etc.
– Function of the inputs: switching, dimming, shutter control, light scene exten-
sion unit, brightness or temperature value transmitter
– Optional: external temperature sensor, connectable (accessories)
6 Information for electrically skilled persons
6.1 Mounting and electrical connection
DANGER!
Electric shock when live parts are touched.
Electric shocks can be fatal.
Cover up live parts in the installation environment.
Mounting notes
Do not use controllers in multiple combinations with electrical devices. Their heat de-
velopment will influence the temperature measurement of the controller.

Do not mount controllers near sources of interference, such as electric cookers, refri-
gerators, draughts or direct sunlight. This would influence the temperature measure-
ment of the controller.
Observe the routing conditions for SELV.
Do not route input cables parallel to mains cables. Otherwise there might be EMC in-
terference.
Recommendation: Use a deep appliance box.
The optimum installation height is approx. 1.5 m.
Mounting and connecting the device
￭ Separate the connection terminal insert (1) and the electronics cover (3)
(see figure 1).
￭ Connect the bus line to the device connection terminal (9) in the connection
terminal insert (see figure 2).
Figure2
￭ Binary inputs E1…E4: Connect the NO or NC contact as switch or push-button
to the connection terminals 1 and 2…5 (see figure 3) of the terminal strip (8)
(see figure 2).
￭ Binary outputs A1…A2: Connect the LED or electronic relay to the connection
terminals 1 and 2, 3 (see figure 4) of the terminal strip (8) (see figure 2).
The specification of the function as inputs/outputs depends on the ETS pro-
gramming.

Figure4
Optional: Route an external temperature sensor in an empty pipe and guide the
sensor head out at the measurement location.
Select the installation location for the temperature sensor so that it can measure the
temperature without any influence from sources of interference.
￭ Connect the external temperature sensor to the connection terminals 5 and 6
(see figure 4) of the terminal strip (8) (see figure 2).
The sensor cable can be extended up to a maximum of 50 m with a twisted
pair cable, e.g. J-Y(St)Y-2x2x0.8. When using the KNX bus line: use a second
pair of yellow/white cores.
￭ Insert the connection terminal insert (1) (see figure 1) in the flush-mounted ap-
pliance box. Observe the labelling OBEN / TOP. The bus connection (9)
(see figure 2) must be at the bottom, right.
￭ Fit the cover frame (2) on the connection terminal insert (1) (see figure 1).
￭ Insert the electronics cover in the correct position into the connection terminal
insert (see figure 1).
￭ Remove the cover (4) (see figure 1).
￭ Fasten the electronics cover with the retaining screw (5) (see figure 1).
￭ Reattach the cover (4) (see figure 1).
6.2 Commissioning
Loading the address and the application software
￭ Remove the cover (4) (see figure 1).
￭ Press the programming button (7) (see figure 1).
The programming LED (6) is illuminated (see figure 1).
￭ Assign a physical address.
The programming LED (6) goes out (see figure 1).
￭ Note down the physical address on the connection terminal insert and on the
back of the electronics cover.

Observe the correct assignment of inserts and covers when assembling after
painting or wallpapering.
￭ Reattach the cover (4) (see figure 1).
￭ Download the application software, parameters, etc.
