Sensors Intra-Sewi KNX TH-L-Pr and Intra-Sewi KNX L-Pr
• Version: 30.08.2018 • Technical changes and errors excepted.
Threshold value setting using parameter:
Set the threshold values and hysteresis directly.
Threshold value setting using a communication object:
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 humidity range is specified 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.
Set the
hysteresis
independent of the type of threshold value specification.
Switching output
Set the behaviour of the switching output when a threshold value is exceeded/under-
cut. The output switching delay can be set using objects or directly as a parameter.

When the following conditions apply,
the output is
(TV = Threshold value)
• TV above = 1 | TV - hyst. below = 0
• TV above = 0 | TV - hyst. below = 1
• TV below = 1 |TV + hyst. above = 0
• TV below = 0 |TV + hyst. above = 1
