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).

2.5. Notes on mounting and commissioning

Never expose the device to water (e.g. rain) or dust. This can damage the electronics. You must not exceed a relative humidity of 85%. Avoid condensation.
The air slots on the side must not be closed or covered.
After the bus voltage has been applied, the device will enter an initialisation phase last­ing a few seconds. During this phase no information can be received or sent via the bus.
Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D • Version: 10.09.2018 • Technical changes and errors excepted.
12 Addressing the equipment

3. Addressing the equipment

The equipment is delivered with the bus address 15.15.254. You can program a differ­ent address in the ETS by overwriting the address 15.15.254 or by teaching the device via the programming button.
The programming button is on the inside of the housing (Fig. 2: No. 3).

4. Maintenance

The air slots on the side must not get dirty or covered. As a rule, it is sufficient to wipe the device with a soft, dry cloth twice a year.
