5 Description

Sensors Vari KNX 3L • Version: 18.06.2019 • Technical changes and errors excepted.

1. Description

The Sensors Vari KNX 3L for the KNX building bus system record brightness (sun)

and additionally temperature, air humidity and air pressure outside, depending on the

model. The model Vari KNX 3L-TH-D GPS also receives the GPS signal for time and lo-

cation 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 out-

puts. States can be linked via AND logic gates and OR logic gates. Multi-function mod-

ules change input data as required by means of calculations, querying a condition, or

converting the data point type.

Models with a temperature sensor have an integrated PI controller for heating/cooling.

Models with humidity sensor have a PI controller for ventilation.

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

cuits and bus-coupling electronics.

Functions 70382 Vari KNX 3L:

•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

Additional functions of the models with temperature sensor:

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

70389 Vari KNX 3L-TH-D, 70390 Vari KNX 3L-TH-D GPS)

•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, 70389 Vari KNX 3L-TH-D, 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.

6 Description

Sensors Vari KNX 3L • Version: 18.06.2019 • Technical changes and errors excepted.

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 of the models with air pressure sensor:

(70389 Vari KNX 3L-TH-D, 70390 Vari KNX 3L-TH-D GPS)

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

optionally as barometric pressure

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

•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 down-

loaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Ser-

vice” menu.
