1 Safety instructions
Electrical equipment must be installed and fitted by qualified
electricians only. Observe the current accident prevention regulations.
Failure to observe the instructions may cause damage to the device
and result in fire or other hazards.
The device is not suited for safe disconnection of the mains supply.
Do not connect consumers for SELV / PELV voltages..
Connect only electro-thermal valve drives to the heating outputs. Do
not connect inductive or capacitive loads.
Do not operate electro-thermal valve drives with DC voltage. Do not
connect three-phase AC motors.
These operating instructions are part of the product and must be left
with the final customer.

3 Function
3.1 System Information
This device is a product of the KNX system and complies with KNX
directives. Detailed technical knowledge obtained in KNX training courses is
a prerequisite to proper understanding.
The functionality of this device depends on the software.
Detailed information on loadable software and attainable functionality as
well as the software itself can be obtained from the manufacturer‘s product
database.
Planning, installation and commissioning of the unit is effected by means of
KNX-certified software. The full functionality is available with KNX

commissioning software from version ETS3.0d onwards.
The product database, technical descriptions, conversion programs and
other utilities are available in their latest version on our Internet page.
3.2 Designated use
• Switching of electrical consumers AC 230 V with potential-free contacts
• Switching of electrically operated blinds, shutters, awnings and similar
curtains
• Heating outputs: electronic outputs for switching electro-thermal valve
drives
• - Installation on DIN rails in small distribution boards
Product features
• Manual output control, provisional operation
• Feedback in manual control mode and in bus operation
• Scene function
• Disabling of individual outputs by hand or via the bus
Switching function
• Make-contact and break-contact operation
• Logic operation and forcing function
• Feedback function
• Central switching function with group feedback
• Time functions: ON-delay, OFF-delay, staircase lighting timer with early-
warning function
Blind/shutter function
• Suitable for AC motors 230 V
• Direct control of blind/shutter position
• Direct control of slat position
• Checkback of running state, blind/shutter position and slat position
• Forced-control position from primary control
• Safety function: 3 independent wind alarms, rain alarm, frost alarm
• Sun protection function
Control of valve drives
• Switching or PWM operation
• Control of valve drives with working characteristics „normally open“ or
„normally closed“
• Overload and short-circuit protection
• Emergency operation in the event of bus failure for summer and winter
• Protection against jamming valves
• Forced-control position
• Cyclical monitoring of input signals parametrizable
L PWM operation: Electro-thermal valve drives only have an „open“ and a
„closed“ position. In PWM operation, these devices have quasicontinuous characteristics due to fast switching within the cycle time.

4 Operation
4.1 Controls
Fig.2: Controls – layout
(5) output status LEDs
(9) key : Manual control
(10) LED
: permanent manual control indicator
(11) key ON/ : switching on or opening a valve or raising a curtain / stop
(12) LED ON/ : lit up: switched on or blind/shutter moving upwards,
manual control mode
(13) key
OFF/ : switching off or closing a valve or lowering the
blind/shutter / stop
(14) LED
OFF/ : lit up: switched off or blind/shutter moving down,
manual control mode
(15) ALL OFF key: all outputs off, closing all valves and stopping all
drives
4.2 Status indication
The status LEDs A1...A6 (Fig. 2, 5) indicate the output states.
• Off: output is off
• On: output is on
• Flashing slowly: output in manual control mode
• Flashing fast: output disabled by permanent manual control mode
Heating outputs A5 and A6: The LED does not indicate the characteristics
of the valve drive, but the state of the output. ON = supplying current; OFF =
not supplying current.
In the PWM mode of operation, the LED indication cannot be interpreted as
representing the state of the valve drives connected and of the valves
controlled
4.3 Modes of operation
• Bus operation: operation via touch sensors or other bus devices
• Temporary manual control: manual operation locally with keypad,
automatic return to bus operation
• Permanent manual control mode: only manual operation locally on
device
L Bus operation in manual control mode disabled.
L Manual operation in the event of bus failure enabled.
L After failure and return of bus voltage, the device switches over to bus
operation.
