Operating instructions

1 Safety instructions

Electrical equipment may only be installed and fitted by electrically skilled persons.

Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.

Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.

Danger of electric shock. Device is not suitable for disconnection from supply voltage.
The load is not electrically isolated from the mains even when the device is switched off.

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 KNX-certified software. The latest versions of product database and
the technical descriptions are available on our website.

Intended use

- Switching of electrothermal actuators for heaters or cooling ceilings

- Installation in distribution boxes on DIN rail according to DIN EN 60715

Product characteristics

- Switching operation or PWM operation

- Actuators with characteristics opened or closed without power

- Overload-protected, short circuit-protected

- Protection against jamming valves

- Forced position

- Various setpoints for forced position or emergency operation in case of bus failure for

summer or winter

- Cyclical monitoring of the input signals can be parameterized

- Feedback via bus, e.g. in case of mains failure, overload or sensor failure

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.

Overload protection

In order to protect the device and connected actuators, in case of overload the device
determines which output is involved and switches it off. Non-overloaded outputs continue to
work, which means that the rooms in question are still heated.

- In case of major overloads the actuator initially switches all off the outputs A1...A6 off.

- In the case of more minor overloads the actuators switches output groups A1...A3 and/or

A4...A6 off.

- The actuator determines the overloaded output in up to 4 test cycles.

- If in the event of only a minor overload it is not possible to unambiguously identify any

output as overloaded, then the actuator switches individual outputs off one after the other.

- The overload can be reported to the bus for each output.

4 Information for electrically skilled persons

4.1 Fitting and electrical connection

DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the

corresponding circuit breakers. Cover up live parts in the working environment.

Fitting the device

Observe the temperature range. Ensure adequate cooling.
o Mount device on DIN rail. Output terminals must be at the top.
