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.

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).
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 controller has various operating modes available
for this.
Icons of the electronics cover:
| Comfort operating mode
---|---
| Standby operating mode
| Night operating mode
| Frost/heat protection operating mode
| Comfort extension / night operating mode
| Comfort extension / frost / heat protection operating mode
| Heating/cooling indication active
| Heating mode indication
| Cooling mode indication
| Controller 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 or 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.
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.
Mounting and connecting the device
(4) Connection terminal insert
(5) Cover frame
(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).
￭ 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 terminal 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
programming.
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 appliance box. Observe the labelling OBEN / TOP. The bus connection
(11) must be at the bottom, right (see figure 3).
￭ Fit the cover 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).
5.2 Commissioning
Loading the address and the application software
￭ Pull off the adjustment dial (2) (see figure 2).
￭ Press the programming button (9).
The programming LED (8) is illuminated.
￭ Assign a physical address.
The programming LED (8) goes out.
￭ 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.
￭ Refit the adjustment dial (2).
￭ Download the application software, parameters, etc.
