1 General

Modern building installation enables a high degree of functionality and simultaneously complies with

increased security requirements. Due to the structured installation of the electrical components, it is

possible to carry out rapid planning, installation and commissioning as well as achieve cost benefits during

operation. With individual room control, potential savings of up to 25 % of the energy consumption can be

achieved.

The technical systems for control of the room temperature and air quality consume the largest share of

energy in a building. Accordingly, the largest savings can be made here. Mistaken or incorrect operation

can lead to expensive waste of energy. High levels of energy consumption are greatly reduced or avoided

by optimisation of a building with regard to the architecture, construction and installation engineering.

On a room level, the KNX intelligent installation systems support the user in optimisation of the energy

consumption and provide information to the installation engineering or the building control engineering for

optimisation of the setting parameters. By detecting the actual temperature value and specifying a

respective temperature setpoint with a control algorithm, the thermostat sends a control value to the

actuator, e.g. the Valve Drive Actuator VAA/S x.230.2.1. This controls an Electrothermal Valve Drive, e.g.

TSA/K. This on the other hand opens or closes a value of a heating or cooling unit, e.g. underfloor heating.

This then changes the room temperature. An additional presence detector used for control of the room

lighting can simultaneously switch the room thermostat to absent mode as soon as the room is unoccupied

for an extended period. Heating or cooling energy can be conserved in this way.

Practical experience has shown that the reduction of the room temperature by 1 °C can reduce the

consumption of heating energy by 6 %. If the room temperature is reduced by 3 °C during absence, 18 %

of the heating energy can be saved in a non-occupied room.

2.4 Assembly and installation

The ABB i-bus

KNX Valve Drive Actuator VAA/S x.230.2.1 is a modular installation device for quick

installation in the distribution board on 35 mm mounting rails to EN 60 715.

The mounting position can be selected as required.

The electrical connection is implemented using screw terminals. The connection to the bus is implemented

using the supplied bus connection terminal. The terminal assignment is located on the housing.

The device is ready for operation after connection to the bus voltage. If bus voltage is not yet available at

the time of commissioning, the device can be supplied with power for operation of the manual buttons

using the Power Supply NTI/Z.

Accessibility to the device for the purpose of operation, testing, visual inspection, maintenance and repair

must be provided compliant to VDE 0100-520.

Commissioning requirements

In order to commission the device, a PC with ETS and a KNX interface, e.g. USB or IP, are required. The

device is ready for operation after connection to the bus voltage.

The installation and commissioning may only be carried out by qualified electrical specialists. The

appropriate norms, guidelines, regulations and specifications for your country should be observed when

planning and setting up electrical installations and security systems for intrusion and fire detection.

Protect the device from damp, dirt and damage during transport, storage and operation.

Only operate the device within the specified technical data limits!

The device should only be operated in an enclosed housing (distribution board)!

The voltage supply to the device must be switched off, before mounting work is performed.

Danger

In order to avoid dangerous touch voltages, which originate through feedback from differing phase

conductors, all-pole disconnection must be observed when extending or modifying the electrical

connections.

Manual operation

The device incorporates manual operating features. Special device functions can be undertaken using the

operating keys on the foil keypad.

Supplied state

The device is supplied with the physical address 15.15.255. The application program is preloaded. It is

therefore only necessary to load group addresses and parameters during commissioning.

However, the complete application program can be reloaded if required. A longer downtime may result if

the application program is changed or after a discharge.

Assignment of the physical address

The assignment and programming of the physical address is carried out in the ETS.

The device features a

button for assignment of the physical device address. The red LED lights up,

after the button has been pushed. It switches off as soon as the ETS has assigned the physical address or

the button is pressed again.

Download response

Depending on the PC, which is used, the progress bar for the download may take up to one and a half

minutes, before it appears, due to the complexity of the device.

Cleaning

If devices become dirty, they can be cleaned using a dry cloth or a cloth dampened with a soapy solution.

Corrosive agents or solutions should never be used.

Maintenance

The device is maintenance-free. No repairs should be carried out by unauthorised personnel if damage

occurs, e.g. during transport and/or storage.

2.5 Manual operation

General

The outputs can be directly controlled using the buttons in manual operation.

Accordingly, the wiring of the loads connected to the outputs can be verified during commissioning. You

can, for example, ensure that the connected valve drives open or close the valves correctly. If bus voltage

is not yet available at the time of commissioning, the device can be supplied with power for manual

operation using the Power Supply NTI/Z.

Function of manual operation

Manual operation facilitates on-location operation of the device. As standard the button

Manual

operation is enabled and can be switched on and off using it.

Switch on of manual operation:

Press button until the yellow LED lights continuously.

Switch off of manual operation:

Press button

until the yellow LED switches off.

The yellow LED flashes during the switchover process.

After connection to the KNX, an ETS download or ETS reset, the device is in KNX operation. The LED

Note

If the Manual operation is generally disabled or disabled via communication object Disable/enable man.

operation, the LED

flashes during a button push.

A switchover from KNX operation to the Manual operation mode does not occur.

Important

If manual mode is activated, it has a higher priority than other functions, e.g. safety. As soon as the

output state is modified in manual mode via button Output, active functions, such as blocking, forced

operation and valve purge are interrupted and values of the characteristic curve are not considered.

Manual operation is inactive after bus voltage recovery, download or ETS reset.

Supplied state

Manual operation is enabled by default in the supplied state. The device is in KNX operation after

connection to the bus. The yellow LED

is off. All LEDs for the outputs indicate the actual state. The

buttons for the outputs are non-functional.

Telegram processing with active manual operation

Incoming telegrams will continue to be received and saved during active manual operation. After manual

operation is deactivated, the device will update.

If a telegram with the value 1 is received via communication object Enable/block manual operation, active

manual operation is deactivated and then blocked. Manual operation can no longer by activated by the

manual buttons.

2.5.2 Operating controls

Buttons for manual operation are located on the front of the device.

If manual operation is activated, the current control value of the respective output is retained and the

yellow LEDs on the outputs indicate the current status (ON/OFF). A target position, which may not have

yet been achieved, is approached. The outputs can now only be operated via the manual buttons for the

outputs. The first button push switches on the output if the control value = 0. If the control value > 0, the

output is switched off. Every subsequent button push toggles the output.

The behaviour of the operating elements dependent on the operating states, KNX operation and Manual

operation is described in the following table:

Button KNX operation Manual operation

Manual operation

Long button operation (about 3 sec.): Switch to Manual

operation, provided that Manual operation is not blocked

by a parameter setting.

Short button push: LED Manual operation flashes and

switches off again. The device is once again in Manual

operation

Long button operation (about 3 sec.): Changeover to the

KNX operation. The inputs are queried again, and the

input states are updated accordingly.

The reset of Manual operation to KNX operation can be be

undertaken in a programmable time, depending on the

parameterization.

Output A…X

No reaction

By pressing button output A is switched on or off. A

connected valve drive opens/closes the valve.

The display indicates the current switching state of the

output.

Reset

output group. The button

must be pushed until the red

LED switches off, for this purpose.

The button function is inactive during an ongoing short-

circuit test.

3.1.1 Conversion

For ABB i-bus

KNX devices from ETS3 or higher, it is possible to assume the parameter settings and

group addresses from earlier application program versions.

Furthermore, conversion can be applied to transfer the existing parameterization of a device to another

device.

Note

When the term “channels” is used in the ETS, inputs and/or outputs are meant. In order to ensure that

the ETS language generally applies for as many ABB i-bus

devices as possible, the word channels is

used here.
