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.
The device can be updated. Firmware can be easily updated with the Gira ETS Ser-
vice App (additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against
manipulation in building automation and can be configured in the ETS project. De-
tailed specialist knowledge is required. A device certificate, which is attached to the
device, is required for safe commissioning. During mounting, the device certificate
must be removed from the device and stored securely.
Planning, installation and commissioning of the device are carried out with the aid of
the ETS, version 5.7.7 and above.
Intended use
– Switching of electrothermal valve drives for heaters or cooling ceilings
– Operation in KNX system
– 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
– Outputs can be operated manually, construction site mode
– Feedback in manual operation mode and in bus mode
– Disabling of individual outputs manually or by bus
– Overload-protected, short-circuit-protected, error message with LED
– Protection against jamming valves
– Forced position
– Cyclical monitoring of the input signals can be parameterized
– Feedback via bus, e.g. in case of mains failure or overload
– 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.

Heating actuator 6-gang with controller
– Integrated room temperature control with setpoint value specification
– 12 independent controllers to control up to 12 independent rooms
– Controller function for heating and cooling operation
Overload / short-circuit 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 the event of an overload, group monitoring switches off the affected output
group A1...A3 or A4...A6 first.
– Unambiguous monitoring 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.
LED display:
All status LEDs of the affected valve group flash synchronously during the test (1s
flash -> 1s pause -> 1s flash -> ...).
– Overload: Status LED of the identified output flashes continuously (approx. 2
Hz): Test cycle completed.
– Short-circuit: Status LED of the identified output flashes continuously (approx.
1 Hz): Test cycle completed.

LED – On: valve opened, manual operation mode
(9) Close button – Close valve
LED – On: valve closed, manual operation mode
(10) ALL OP / CL button – Central operating function for all outputs in case of
permanent manual operation: Open and close all valves alternately
Status display and output behaviour
The status LEDs A1...A6 (3) show whether the current flow is switched on or
switched off at the appropriate output. The connected heating or cooling valves open
and close according to their characteristics.
Valve drive Status LED on Status LED off
Deenergised closed Heating/cooling
Valve opened
Valve closed
Deenergised opened Valve closed Heating/cooling
Valve opened
– Status LED flashes slowly: output in manual operation mode
– Status LED flashes quickly: output disabled via permanent manual operation
mode
Operating modes
– Bus operation: operation via push-button sensors, for example
– Temporary manual operation mode: manual operation on device with button
field, automatic return to bus mode
– Permanent manual operation mode: exclusively manual operation on the
device
No bus operation is possible in manual operation mode.
All controlled valve outputs switch off after bus voltage failure.

5 As-delivered state
In the as-delivered state, the device enables manual operation on the device itself,
provided that the voltage supply to the valve drives and the bus voltage are switched
on. With manual operation, no feedback telegrams are sent to the KNX.
In the as-delivered state, all the valve outputs are configured as follows:
– Valve direction of action: Deenergised closed
– Pulse width modulation on "Open valve": 50%
– Cycle time: 20 minutes
– Behaviour in case of bus voltage failure: Valves set to deenergised state
(valve outputs switched OFF)
– Behaviour in case of bus voltage return: Valves set to deenergised state (valve
outputs switched OFF)
