Flush-mounted room climate interface with satellite input
Art.-No.: 2531 UP
Operationsmanual
1 Safety instructions
Electrical equipment may only be installed and fitted by qualified electricians.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
The device is not suitable for disconnection from supply voltage.
The connected actuators are not electrically isolated from the mains – even when
switched off.
Do not connect any external voltage to the inputs, since doing so may damage the
device(s), and the SELV potential on the KNX bus line will no longer be available.
For parallel connection of several drives to an output it is indispensable to observe the
corresponding instructions of the manufacturers, and to use a cutoff relay if necessary.
There is otherwise risk of irreparable damage to the drives.
Use only Venetian blind drives with mechanical or electronic limit switches. Check the
limit switches for correct adjustment. Observe the specifications of the motor
manufacturers.
These instructions are an integral part of the product, and must remain with the end
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 to proper
understanding.
The function of this device depends upon 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 device are carried out with the aid of KNXcertified software. Full functionality with KNX commissioning software version ETS3.0d
onwards.
An updated version of the product database, technical descriptions and conversion programs
and other auxiliary programs are available on our Internet website.
Intended purpose
- Switching of electrically-driven Venetian blinds, awnings and similar blinds for AC 230 V
mains voltage.
- Switching of electrothermal actuators
- Installation in appliance box to DIN 49073
- Connection with enclosed terminals
Product characteristics
- Control of Venetian blinds, awnings and similar blinds
- Control of electrothermal actuators
- Three binary inputs for potential-free contacts, usable as extension inputs for local
operation
- Supply via bus, no additional power supply necessary
Venetian blind function
- Blind position directly controllable
- Slat position directly controllable
- Feedback of movement status, blind position and slat position
- Forced position through higher-level controller
- Safety function: 3 independent wind alarms, rain alarm, frost alarm
- Sun protection function
Actuator function
- Switching operation or PWM operation
- Actuators with characteristics opened or closed without power

Flush-mounted room climate interface with satellite input
- Overload-protected, short circuit-protected
- Protection against jamming valves
- Forced position
- Cyclical monitoring of the input signals configurable.
i PWM operation: electrothermal actuators only have the positions Open and Closed. In
PWM operation, switch-on and switch-off during the drive's cycle time achieves an almost
constant behaviour.
4 Information for qualified electricians
4.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live
parts in the working environment.
Connecting and mounting the device
DANGER!
When connecting the bus/extensions and mains' voltage wires in a shared
appliance box, the KNX bus cable may come into contact with the mains
voltage.
The endangers the safety of the entire KNX installation. People at remote
devices may also receive an electric shock.
Do not place bus/extensions and mains voltage terminals in a shared
connection compartment. Use an appliance box with a fixed partition wall
(picture 3) or separate boxes.
