Basic heating actuator 6-gang

1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled
persons.
Serious injuries, fire or property damage possible. Please read and follow manual
fully.
Danger of electric shock. Device is not suitable for disconnection from supply voltage
because mains potential even is applied on the load when the device is switched off.
Before carrying out work on the device or load, switch off all associated circuit break-
ers.
This manual is an integral part of the product, and must remain with the end cus-
tomer.

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 load-
able software and attainable functionality as well as the software itself can be ob-
tained from the manufacturer´s product database. Planning, installation and commis-
sioning 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 valve drives for heaters or cooling ceilings
– Installation in sub-distribution units on DIN rail according to DIN EN 60715
Product characteristics
– Switching operation or PWM operation
– Valve drives with characteristics opened or closed without power controllable
– Valve drives 230 V or 24 V controllable
– Disabling of individual outputs via bus
– Overload-protected, short circuit-protected
– Protection against jamming valves
– Cyclical monitoring of the input signals can be parameterized
– Feedback via bus, e.g. in case of overload or sensor failure
– Bus connection with standard bus terminal
PWM operation: electrothermal valve drives 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 valve drives, in case of overload or
short-circuit 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 out-
puts off one after the other.
– The overload can be reported to the bus for each output.

4 Information for electrically skilled persons
4.1 Mounting and electrical connection
DANGER!
Electric shock when live parts are touched.
Electric shocks can be fatal.
Before working on the device, disconnect all the corresponding circuit breakers.
Cover up live parts in the working environment.
Mounting the device
Observe the temperature range. Ensure adequate cooling.
￭ Mount device on DIN rail. Output terminals must be at the top.
Connecting the device
Image2: Connection of actuators 230 V
Connect valve drives of AC 230 V or AC 24 V to all the outputs.
Only connect valve drives with the same characteristics to each output (deenergised
closed/opened).
Do not connect any other loads.

Connect actuators for frost-sensitive rooms to outputs A1 and A4 . These are
switched off last in the event of overload.
Do not exceed maximum number of valve drives per output (see "Technical data").
Observe the technical data of the valve drives used.
Do not connect the neutral conductor from the output terminals through to additional
devices.
￭ Connect the AC 230 V valve drives according to the connection diagram
(see figure 2).
￭ Connect the AC 24 V valve drives according to the connection diagram
(see figure 3).
￭ Connect the supply for the valve drives to the terminals 8(L) and 8(N) (1).
￭ Connect bus line with device connection terminal.

Installing the cover
It is necessary to install a cover to protect the bus connection against hazardous
voltages in the connection area.

Image4: Installing the cover
￭ Route the bus line towards the rear.
￭ Install cover on top of the bus terminal so that it snaps into place
(see figure 4).
Removing the cover
Image5: Removing the cover
￭ Press the cover to the side and pull it off (see figure 5).
4.2 Commissioning
Load the address and the application software
￭ Switch on the bus voltage.
￭ Press the programming button.
￭ Load the physical address into the device.
￭ Load the application software into the device.
￭ Note the physical address on the device label.

6 Troubleshooting
Valve drives of an output or all outputs do not switch
Cause: An output is overloaded.
Determine cause of the overload switch-off. Eliminate short-circuits, replace de-
fective valve drives. Check number of valve drives connected to the output, re-
duce if necessary. Do not exceed max. switching current.
Reset overload switch-off: disconnect device from mains completely for approx.
5 seconds, switch off miniature circuit-breaker. Then switch on again.
In case of overload, initially one or both output groups switch off for approx.
6 minutes. After that the device determines which output is overloaded and
switches it off permanently. This rest and test phase lasts 6 to 20 minutes.
After resetting of the overload switch-off it is no longer possible for the device
to determine which output is overloaded. If the cause is not eliminated, over-
load switch-off will occur again.
