Room temperature controller with push-button interface 4-gang

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.

3 Function
System information
This device is a product of the KNX system and complies with the KNX directives.
Detailed technical knowledge obtained in KNX training courses is a prerequisite for
proper understanding.
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.
Intended use
– Single-room temperature control in KNX installations
– Load types: LED or electronic relay
– Mounting in appliance box with dimensions according to DIN 49073
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
– Dial for setpoint adjustment
– Presence button
– Status LED
– 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)
Functional description
The controller compares the current room temperature with the setpoint temperature
and controls the heating and cooling devices according to the current demand. The
setpoint temperature is determined by the set operating mode and can be varied with
the adjustment dial (2). The selected operating mode and the current controller status
are indicated by the status LED (3) (see figure 1).

4 Operation
Operating modes and Status LED
Each heater requires a certain time to bring a cooled room to the desired temperat-
ure. For this reason, in the event of brief absence, the room temperature can be
lowered only slightly, e.g. by 2 K, and at night by somewhat more, e.g. 4 K. The con-
troller has various operating modes available for this.
Icons of the electronics cover:
0Comfort operating mode
1Standby operating mode
2Night operating mode
¾Frost/heat protection operating mode
02 Comfort extension / night operating mode
0¾ Comfort extension / frost / heat protection operating mode
9Heating/cooling indication active
4Heating mode indication
5Cooling mode indication
6Controller blocked indication, dewpoint operation
Setting the operating mode
Operating elements for setting the operating mode via the bus are installed, e.g.
push-buttons sensors.
￭ Activate the desired operating mode on the operating element.
Setpoint temperature for the room is set according to the new operating mode.
The new operating mode is indicated by the status LED (3) (see fig. 1).
When the controller state is changed, it may take up to 30 seconds for the
status LED indication to change.
Changing the room temperature
￭ Turn the adjustment dial clockwise.
The setpoint temperature is increased.
￭ Turn the adjustment dial counterclockwise.
The setpoint temperature is lowered.
Activating comfort extension
For automatic changeover from comfort operating mode either to night or frost/heat
protection operating mode by a timer, it is possible to extend the comfort mode. The
programmed time for the presence button is taken into account here.

The controller is in night or frost/heat protection operating mode.
￭ Press the presence button (1) (see Fig. 1).
The status LED 02 or 0¾ light up.
Comfort mode is extended by the programmed time.
Once the programmed time expires, the original operating mode night or frost/
heat protection is restored.
The comfort extension can also be activated automatically, e.g. by a presence
detector.
5 Information for electrically skilled persons
5.1 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.

(6) Electronics cover
(7) Retaining screw
(8) Programming LED
(9) Programming button
￭ Separate the connection terminal insert (4) and the electronics cover (6)
(see figure 2).
￭ Connect the bus line to the device connection terminal (11) in the connection
terminal insert (see figure 3).
Image3: Connection terminal insert
￭ Binary inputs E1…E4: Connect the NO or NC window contacts as switches or
push-buttons to the connection terminals 1 and 2…5 (see figure 4) of the ter-
minal strip (10) (see figure 3).
￭ Binary outputs A1…A2: Connect the LED or electronic relay to the connection
terminals 1 and 2, 3 (see figure 5) of the terminal strip (10) (see figure 3).
The specification of the function as inputs/outputs depends on the ETS pro-
gramming.

Image5: Connection of binary outputs
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 5) of the terminal strip (10) (see figure 3).
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 (4) (see figure 2) in the flush-mounted ap-
pliance box. Observe the labelling OBEN / TOP. The bus connection (11) must
be at the bottom, right (see figure 3).
￭ Fit the design frame (5) on the connection terminal insert (4).
￭ Insert the electronics cover (6) in the correct position into the connection ter-
minal insert (4).
￭ Remove the adjustment dial (2).
￭ Fasten the electronics cover with the retaining screw (7).
￭ Reattach the adjustment dial (2).
