1. Description

The Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D for the KNX bus system
measures the CO

Sewi KNX AQS/TH-D additionally measures the temperature, the air humidity and
the air pressure and calculates the dew-point. The sensor can output a warning to the
bus as soon as the comfort field, as per DIN 1946, is left.

Via the bus, the indoor sensors can receive external values and process it further with
its own data to a total value (mixed value, e.g. room average).

All measurement values can be used for the control of limit-dependent switching out­puts. States can be linked via AND logic gates and OR logic gates. Multi-function mod­ules change input data as required by means of calculations, querying a condition, or
converting the data point type. In addition, an integrated manipulated variable compar­ator can compare and output variables that were received via communication objects.

Integrated PI-controllers control ventilation (according to humidity or CO
tion) and heating/cooling (according to temperature).

Functions:

• Measuring the CO
The share of internal measurement value and external value can be set as a
percentage

• Threshold values can be adjusted per parameter or via communication
objects

• PI controller for ventilation according to CO
(one-stage) or Ventilate (one or two-stage)

• 8 AND and 8 OR logic gates, each with 4 inputs. All switching events as well
as 16 logic inputs in the form of communications objects can be used as inputs
for the logic gates. The output of each gate can be configured optionally as 1­bit or 2 x 8-bit

• 8 multi-function modules (computers) for changing the input data by
calculations, by querying a condition or by converting the data point type

• 4 actuating variable comparators to output minimum, maximum or
average values. 5 inputs each for values received via communication objects

Additional functions Sewi KNX AQS/TH-D:

• Measuring the temperature and air humidity (relative, absolute), each with
mixed value calculation. The share of internal measurement value and

external value can be set as a percentage

• Bus message, whether the values for temperature and air humidity are within
the comfort field (DIN 1946). Dew point calculation

• Air pressure measurement. Output of the value as normal pressure and
optionally as barometric pressure

• PI-controller for heating (one or two-stage) and cooling (one or two-stage)
according to temperature. Regulation according to separate setpoints or basic
setpoint temperature

6 Description

• PI controller for ventilation according to humidity: Ventilate/Air (one-stage)
or Ventilate (one or two-stage)

• Summer compensation for cooling systems. A characteristic curve matches
the target temperature in the room to the external temperature and sets the
minimum and maximum target temperature values

Configuration is made using the KNX software ETS. The product file can be down­loaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Ser­vice” menu.

1.1.1. Measuring accuracy

Deviations in measured values due to interfering sources (see chapter installation site)
must be corrected in the ETS in order to achieve the specified accuracy of the sensor
(offset).

During Temperature measurement, the self-heating of the device is taken into con­sideration by the electronics. The software compensates the self-heating by reducing
the measured temperature by 1.0°C.

2. Installation and start-up

2.1. Installation notes

Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.

CAUTION!
Live voltage!

There are unprotected live components inside the device.

• National legal regulations are to be followed.

• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.

• Do not use the device if it is damaged.

• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.

The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.

After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.

Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D • Version: 10.09.2018 • Technical changes and errors excepted.

8 Installation and start-up

The device may only be used as a fixed-site installation; that means only when assem­bled and after conclusion of all installation and operational start-up tasks and only in
the surroundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.

2.2. Installation location

Install and use only in dry interior rooms! Avoid condensation.

The sensor is installed surface mounted on walls or ceilings.

When selecting an installation location, please ensure that the measurement results of

temperature, humidity and CO

ences. Possible sources of interference include:

• Direct sunlight

• Drafts from windows and doors

• Draughts from ducts coming from other rooms or the outdoors

• Warming or cooling of the building structure on which the sensor is mounted,
e.g. due to sunlight, heating or cold water pipes

• Connection lines and empty ducts which lead from warmer or colder areas to
the sensor

Measurement variations from such sources of interference must be corrected in the
ETS in order to ensure the specified accuracy of the sensor (offset).

Define, how the threshold value is to be received from the bus. Basically, a new value
can be received, or simply a command to increase or decrease.

During initial commissioning, a threshold value must be defined, which will be valid
until the first communication with a new threshold value. For units which have already
been taken into service, the last communicated threshold value can be used. Basically,
a temperature range is given, in which the threshold value can be changed (object
value limit).

A set threshold value will be retained until a new value or a change is transferred. The
current value is saved, so that it is retained in the event of a power supply failure and
will be available once the power supply is restored.

33 Parameter setting

For an adequate regulation of the ambient temperature, comfort, standby, eco and
building protection modes may be used.

Comfort when present,
Standby during short absences,
Eco as a night-time mode and
Frost/heat protection (building protection) e. g. with the window open.

The settings for the temperature control include the setpoint temperatures for the in­dividual modes. Objects are used to determine which mode is to be selected. A change
of mode may be triggered manually or automatically (e.g. by a timer, window contact).

The mode may be switched with two 8 bit objects of different priority. Objects
„... HVAC mode (Prio 2)“ for switching in everyday operation and
„... HVAC mode (Prio 1)“ for central switching with higher priority.
The objects are coded as follows:
0 = Auto
1 = Comfort
2 = Standby
3 = Eco
4 = Building Protection

Alternatively, you can use three objects, with one object switching between eco and
standby mode and the two others activating comfort mode and frost/heat protection
mode respectively. The comfort object blocks the eco/standby object, and the frost/
heat protection object has the highest priority. Objects
„... Mode (1: Eco, 0: Standby)“,
„... comfort activation mode" and
„... frost/heat protection activation mode"

Switch mode via • two 8 Bit objects (HVAC Modes)

• three 1 bit objects

Select the mode to be activated after reset (e.g. power failure, reset of the line via
the bus) (Default).
Then configure a temperature control block via the blocking object.

Mode after reset • Comfort

Behaviour of the blocking object with value • 1 = Block | 0 = release

Value of the blocking object after reset 0 • 1

• Standby

• Eco

• Building protection

• 0 = block | 1 = release

Specify when the current control variables of the controller are to be sent to the bus.
Periodic sending is safer, in case a message does not reach a recipient. You may also
set up periodical monitoring by the actuator with this setting.

Then define the type of control. Heating and/or cooling may be controlled in two le­vels.

Type of control • Single level heating

• Dual-level heating

• Single-level cooling

• Dual-level cooling

• Single-level heating + single-level cooling

• Dual-level heating + single-level cooling

• Dual-level heating + dual-level cooling

General setpoint values

You may enter separate setpoint values for each mode or use the comfort setpoint as
a basic value.
If you are using the control for both heating and cooling, you may also select the set-
ting "separately with switching object". Systems used for cooling in summer and for
heating in winter can thus be switched from one to the other.
If you are using the basic value, only the deviation from the comfort setpoint value is
listed for the other modes (e.g, 2°C less for standby mode).

35 Parameter setting

The increment for the setpoint changes is predefined. Whether the change only re­mains temporarily active (not saved) or is also retained after power supply restoration
(and programming), is specified in the first section of "General control". This also ap­plies to a comfort extension.

Increment for setpoint changes
(in 0.1 °C)

1… 50; 10

The control may be reset to comfort mode from eco mode, which is used as night mo­de, via the comfort extension. This allows the user to maintain the comfort setpoint
value for a longer time, e.g. when having guests. The duration of this comfort extensi­on period is set. After the comfort extension period expires, the system returns to eco
mode.

value is defined for the comfort setpoint as well as a temperature range in which the
setpoint value may be modified.

37 Parameter setting

Setpoint values for frost/heat protection (building protection)

The building protection mode is for example used as long as windows are opened for
ventilation. Setpoints for frost protection (heating) and heat protection (cooling) are
determined which may not be modified from outside (no access via operating devices
etc.). The building protection mode may be activated with delay, which allows you to
leave the building before the controls switch to frost/heat protection mode.

General control variables

This setting appears for the control types "Heating and Cooling" only. Here, you can
decide whether to use a common control variable for heating and cooling. If the 2nd
level has a common control variable, you also determine the control mode of the 2nd
level here.

OFF = 50% control variable
0%...100% cooling = 33%...0% control variable

6.5.1. Heating control level 1/2

If a heating control mode is configured, one or two setting sections for the heating le­vels are displayed.

In the 1st level, heating is controlled by a PI control, which allows to either enter control
parameters or select predetermined applications.

Information on air pressure

The unit for air pressure is Pascal (Pa).
1 Pa = 0.01 hPa = 0.01 mbar

The air pressure is specified as "normal air pressure" or as "barometric pressure".
The normal air pressure is the pressure compensated for height and temperature. The
barometric air pressure is the pressure measured directly by the sensor (without com­pensation).

be defined via the bus using a communication object.

Setpoint value setting using parameters:

Set the setpoint value directly.

Setpoint value setting via communication object:

Enter, how the setpoint value will be received from the bus. Basically, a new value can
be received, or simply a command to increase or decrease.

During initial commissioning, a setpoint value must be defined which is valid until the
first communication of a new setpoint value. For units which have already been taken
into service, the last communicated setpoint value can be used. Basically, an air humi­dity range is given in which the setpoint value can be changed (object value limit).

A set setpoint value will be retained until a new value or a change is transferred. The
current value is saved, so that it is retained in the event of a power supply failure and
will be available once the power supply is restored.

Ventilation control

Depending on the control mode, one and/or two setting sections for the ventilation sta­ges are displayed.

For two-stage ventilation, the setpoint value difference between the two stages must
be defined, i.e. the setpoint value which, when exceeded, triggers the switch to the 2nd
level.

Target value difference between 1st and
2nd level in ppm

(for level 2 only)

Determine the deviation from the setpoint value at which the maximum variable value
is reached, i.e. the point at which maximum output is used.
The reset time shows how quickly the controller responds to deviations from the set­point value. In case of a short reset time, the control responds with a fast increase of
the control variable. In case of a long reset time, the control responds somewhat less
urgently and needs longer until the necessary control variable for the setpoint value
deviation is reached.
You should set the time appropriate to the ventilation system at this point (follow the
manufacturer's instructions).
