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.

2.5 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
is
off. All LEDs indicate the actual input state.
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.

VAA/S x.230.2.1 | 2CDC 508 101 D0201 15
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
For resetting a fault, e.g. short-circuit or overload of an
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.
