1 About this document
The Commissioning manual is a supplement to the addendum of the IQ box KNX. It provides comprehensive
documentation about the commissioning and setting parameters of the GEZE IQ box KNX.
Knowledge of the KNX Bus System and of the KNX ETS software from version 4.0 is required for setting the param-
eters and for integrating the IQ box KNX into a KNX bus system.
1.1 Product description and compatibility
The IQ box KNX makes the control and monitoring of the GEZE IQ windowdrives (Slimchain, Powerchain, E 250 NT,
Power lock, etc.) via the KNX-bus system possible. The drives can be moved to the required positions and the cur-
rent drive position and various drive states can be requested. Two additional binary inputs can be used either for
direct operation (e.g. manual push buttons) or as bus inputs. Conguration is done using the KNX software ETS
(from version 4.0). The ETS product database can be downloaded via the internet from www.geze.com or directly
from www.iq-box-knx.geze.de.
The IQ windowdrives used for operating the IQ box KNX must have software version 3.0 or higher. The SW ver-
sion of the drives is shown on the packaging label and on the identication plate.

In the case of 24 V DC and a longer power supply line, the cable must have a suciently large cross-section in order to
prevent a voltage drop. Calculate the cross-section.
The overall cable length between IQ box KNX and window must not exceed max. 15 m.
With Synchro or locking drives, all the individual drive cables count.
Note the wiring diagram for IQ windowdrives ID 148327.
Can only be used with GEZE IQ windowdrives from software version 3.0 onwards.
5 Test operation and commissioning of the IQ windowdrives
5.1 Test operation
Following connection of the drives and the 24 V supply voltage, the key “Window OPEN”(9) and the key“Window
CLOSED” (8) (see g. IQ box KNX top hat rail + ush mounting) can be use to carry out a test run, even if the KNX
system has not been programmed at this point.
If the IQ windowdrives are being operated for the rst time, the closing position of the window is detected
during the rst closing procedure and is saved automatically. Should the drive reverse after reaching the closing
position (drive opens by approximately 15 mm), a commissioning run must be started. See wiring diagram for IQ
windowdrives ID 148327.
With the chain drives Slimchain/Powerchain, the ventilation stroke ex works is limited to 300 mm in the software
of the drives. In KNX mode, the maximum pre-set ventilation stroke can be approached. The ventilation stroke can
be adjusted in the drive software via the GEZE ST 220 and the GEZE service case. The maximum ventilation stroke
is prescribed by the nominal stroke of the drives.
5.2 KNX commissioning
The KNX bus cable and the 24 V supply must be connected for the commissioning of the IQ box KNX. The drives
can also be connected subsequently.
5.2.1 Load ETS product database IQ box KNX
In order to set the parameters of the IQ box KNX via the ETS software (from version 4.0), the product database le
must be loaded. The ETS product database can be downloaded via the internet from www.geze.com or directly
from www.iq-box-knx.geze.de.
5.2.2 Assign physical address of the IQ box KNX
From the factory, the IQ box KNX has the physical address 15.15.255. In the KNX-Bus-System, an individual physi-
cal address must be specied for each KNX participant using the ETSasoftware.
Before or during the programming procedure of the physical address, the KNX programming button (11) of the IQ
box KNX must be pressed. KNX programming LED turns red. No other KNX participants may be in programming
mode while assigning the address.

Operation Manual controls There are several possibilities for the manual controls via KNX:
àAddressing the movement command Open/Close (KNX
Com. Object # 1)
àAddressing the movement command Open/Close (KNX
Com. Object # 1) and Stop (KNX Kom. Object # 2) long-
term and short-term function for blinds operation
àAddressing the movement command target position by
stating percentage (KNX Com. Object # 3)
Operation Speed
Manual controls
Open/Close speed as a percentage of the max. ventilation
speed of the drive in manual mode (actual max. ventilation
speed depending on load).
To secure windows against jamming, a leaf speed of < 5
mm/s can be required within the framework of a safety
analysis.
Drive noise increases as speeds increase.
Operation Interval ventilation Settable step width in %, by which the window is moved when
opening or closing when pressing the button. Additional
pushes of the button are accumulated. Interval ventilation can
be controlled using the blinds function like the normal manual
controls. Open/Close over long-term operation and Step/Stop
over short-term operation.
Operation Gap ventilation When triggering the gap ventilation function, the window
is opened to a settable window position in %.
Operation Timed ventilation When the timed ventilation function is triggered, the window
is opened to a window position settable in % and automati-
cally closes again after the end of a settable ventilation period.
Operation Block window 2 block objects, with which the window is closed in manual
mode. Unblocking takes place via the block object.
E.g. for sequence controls with sun protection, blocking the
window if heating or air-conditioning is switched on.
Automatic Automatic mode For automatic control of the windows, e.g. via a central KNX
room/building control unit with dened speed. Lower priority
as manual mode
Automatic Speed automatic Open/Close speed as percentage of the max. ventilation speed
of the drive in automatic mode. (actual max. ventilation speed
depending on load)
To secure windows against jamming, a leaf speed of < 5
mm/s can be required within the framework of a safety
analysis.
Drive noise increases as speeds increase.

Automatic Block automatic Block object, with which opening, closing or opening and clos-
ing of the window is blocked in automatic mode.
Unblocking takes place via the block object. Alternatively, via a
settable blocking time.
E.g. for sequence controls with sun protection, blocking the
windows if heating or air-conditioning are switched on.
Status messages Send current position The drive position is sent after a settable position change in %.
Status messages Send status messages During a change, or after a settable cycle time, the following
status messages are sent by the window:
àTemporary position
àOpened
àClosed
àNot closed
àIs opened
àIs closed
Alarm Reaction to safety alarm If there is a safety alarm with the highest priority, the window
can be opened and closed. When opening, the drive moves at
maximum alarm speed, when closing at maximum ventilation
speed. (Not suitable for RWA.)
Alarm Wind alarm/Rain alarm For wind alarm, a binary wind alarm and a wind alarm as
threshold value in m/s can be selected.
After the end of the wind/rain alarm and a settable waiting pe-
riod, the window closes or moves to the last position (depend-
ing on the parameter adjustment).
External push
button
Push button The IQ box KNX has 2 button inputs (terminal 32, 33). The
inputs can be parametrised as local push buttons or KNX but-
tons. Both button inputs can be parametrised individually.
Setting of local push button only controls the directly con-
nected window.
Setting KNX push button generates a KNX communication
object for the push button.
Service Maintenance message Drive sends a maintenance message after 11,000 cycles
Service Fault message Fault messages can be issued for the drives as collective mes-
sage, or as binary message.

àGap ventilation
Open to the dened percentage (e.g. 25%) by press-
ing the push button (local/KNX)
àInterval ventilation
Gradual opening/closing by the interval angle or
percentage (e.g. 25% - 50% - 75% - 100%) through
repeated pressing of the push button (local/KNX)
àTimed ventilation
Open the window to a dened opening position by
pressing the push button (local/KNX) and automatic
closing after a set time

àEasy ventilation controls
All basic functions can be realised through the
grouping of several windows centrally for the entire
ventilation group. For example, pressing a local push
button on an IQ box KNX controls all windows in
parallel.
Example functions:
- Central OPEN (all windows open)/Central CLOSE (all
windows close)
- Central gap, interval and timed ventilation (control
all windows)

àControl several windows in a group or individual
windows
All basic functions can be realised through the
grouping of several windows, also centrally for the
entire ventilation group. For example, pressing a
multiple push button (KNX) controls all windows in
parallel. In addition, an individual control is possible
at any time.
Example functions:
- Central OPEN (all windows open)/Central CLOSE (all
windows close)
- Central gap, interval and timed ventilation (control
all windows)
- Control individual windows (OPEN/CLOSE/gap,
interval and timed ventilation)

àNight cooling
In summer, intelligent ventilation is applied above
certain temperature dierences (between inside and
outside) to lower the indoor temperature.
àControls depending on air quality
If dened threshold values (CO2, temperature,
humidity) are exceeded, intelligent ventilation is ap-
plied until the air quality returns to the requirements.
àControls depending on times of day and usage
Ventilation at certain times, depending on room us-
age (presence of persons in the room)
