Description

The Sensors Vari KNX 3L-T for the KNX building bus system record brightness

(sun), temperature and additionally air humidity and air pressure outside, depen-

ding on the model. The model Vari KNX 3L-TH-D GPS also receives the GPS signal

for time and location and uses it to compute the position of the sun (azimuth and

elevation).

The 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-functi-

on modules change input data as required by means of calculations, querying a

condition, or converting the data point type.

All models have an integrated PI controller for heating/cooling. Models with humi-

dity sensor have a PI controller for ventilation.

The compact housing of the Vari KNX 3L accommodates the sensors, evaluation

circuits and bus-coupling electronics.

Functions of all models:

(70383 Vari KNX 3L-T, 70384 Vari KNX 3L-TH,

70390 Vari KNX 3L-TH-D GPS)

•

Brightness measurement: The current light intensity is measured by three

sensors. Of the three measurement values, the maximum value or a

calculated mixed value can be output optionally.

•

Switching outputs for all measured and computed values. Threshold

values can be adjusted per parameter or via communication objects

•

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 1-bit 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

•

Temperature measurement with mixed value calculation. The share of

internal measurement value and external value can be set as a percentage

•

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

•

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

Additional functions of the models with humidity sensor:

(70384 Vari KNX 3L-TH, 70390 Vari KNX 3L-TH-D GPS)

•

Humidity measurement (relative, absolute), with Mixed value

calculation. The share of internal measurement value and external value

can be set as a percentage.

In addition the bus output will indicate whether the values are inside the

comfort field (DIN 1946). The dewpoint will be calculated

•

PI controller for humidity according to humidity: Ventilate/Air (one-

stage) or Ventilate (one or two-stage)

•

4 control variable comparators to output minimum, maximum or

average values. 5 inputs each for values received via communication objects

Additional functions 70390 Vari KNX 3L-TH-D GPS:

•

Air pressure measurement: Output of the value as normal pressure and

optionally as barometric pressure

•

GPS receiver, outputting the current time and location coordinates. The

Sensor Vari KNX 3L-TH-D GPS also computes the position of the sun

(azimuth and elevation)

Configuration is made using the KNX software ETS. The product file can be dow-

nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the

"Service" menu.

The product conforms with the provisions of EU directives.

Installation and start-up

Installation, testing, operational start-up and troubleshooting should

only be performed by an authorised electrician.

CAUTION!

Live voltage!

There are unprotected live components inside the device.

• Inspect the device for damage before installation. Only put undamaged

devices into operation.

• Comply with the locally applicable directives, regulations and provisions

for electrical installation.

• Immediately take the device or system out of service and secure it against

unintentional switch-on if risk-free operation is no longer guaranteed.

Use the device exclusively for building automation and observe the operating ins-

tructions. Improper use, modifications to the device or failure to observe the ope-

rating instructions will invalidate any warranty or guarantee claims.

Operate the device only as a fixed-site installation, i.e. only in assembled condition

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.

2.1. Installation location

Due to the GPS receiver, the Sensor Vari KNX 3L-TH-D GPS must be installed

outside. The other models can be mounted outside or inside.

The Vari KNX 3L-TH-D GPS and Vari KNX 3L-TH should be protected from

condensation. For critical applications in which the formation of condensation is

expected, please consult Elsner Elektronik about special solutions.

The device must be attached to a ver-

tical wall (or a pole).

The device must be mounted in the

horizontal (transverse) direction.

Horizontal

Select an installation position on the building where the sensors can measure

sunshine without any obstructions. The weather station should not be shaded by

structures or, for example, trees. Ensure no shadow is thrown on the device by an

extended awning.

For installation in the northern hemis-

Wall/Pole

North

phere, the device must be aligned to

face south.

For installation in the southern hemis-

phere, the device must be aligned to

South

face north.

Temperature measurements can also be distorted by external influences such as

warming or cooling of the building structure on which the sensor is mounted (sun-

light, heating or cold water pipes). Temperature variations from such sources of in-

terference must be corrected in the ETS in order to ensure the specified accuracy

of the sensor (temperature offset).

Note for devices with GPS receiver:

Magnetic fields, transmitters and interference fields from electrical consumers

(e.g. fluorescent lamps, neon signs, switch mode power supplies etc.) can block or

interfere with the reception of the GPS signal.
