The Temperature Sensor KNX T-UN consists of evaluation electronics and measuring
sensor. The sensor measures temperature in indoor and outdoor areas. The sensor can
receive an external measured value via the bus and process it with the own data to an
overall temperature (mixed value). The KNX T-UN provides four switching outputs with
adjustable threshold values as well as additional AND and OR logic gates. The sensor
has got a PI controller for heating and cooling.
Functions:
•
Measurement of
temperature
•
Mixed value
from own measured value and external value (proportions can be set in
percentage)
•
PI controller for heating
(one or two step) and cooling (one or two step)
•
4 switching outputs
with adjustable threshold values (Threshold values can be set
by parameter or via communication objects)
•
4 AND and 4 OR logic gates
with each 4 inputs. Every switching incident as well
as 8 logic inputs (in the form of communication objects) may be used as inputs for
the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8
bits
Configuration is made using the KNX software ETS. The
programme file
(format VD2)
and the
manual
can be downloaded from the Elsner Elektronik homepage on
