• Version: 30.08.2018 • Technical changes and errors excepted.
The
minimum and maximum readings
can be saved and sent to the bus. Use the
"Reset temperature min/max. value" objects to reset the values to the current readings.
The values are not retained after a reset.

Temperature threshold values
The chapter "Temperature threshold values" only applies to the TH-L-
Pr model.
Activate the required temperature threshold values. The menus for setting the th-
reshold values are displayed.
5.8.1. Threshold value 1, 2, 3, 4
Threshold value
Set, in which cases
threshold values and delay times
received via object are to be
retained. The parameter is only taken into consideration if the setting via object is ac-
tivated below. Please note that the setting "After power supply restoration and pro-
gramming" should not be used for the initial start-up, as the factory settings are always
used until the first communication (setting via objects is ignored).
Set the threshold value directly in the application program using parameters, or define
them via the bus using a communication object.
Threshold value setting via parameter:
Set the threshold values and hysteresis directly.
Threshold value setting via 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,
