12 Setting parameters
Temperature Sensor KNX T-AP • Version: 27.01.2020 • Errors excepted. Subject to technical changes.
During initial commissioning, a threshold value must be defined which will be valid un-
til the first call with a new threshold value. For units which have already been taken into
service, the last communicated threshold value can be used. Basically, a temperature
range is given 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 in EEPROM, so that this is retained in the event of a power sup-
ply failure and will be available once the power supply is restored.
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.
Blocking
The switching output can be blocked using an object. Define specifications here for the
behaviour of the output when blocked.

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 + hysteresis above = 0
• TV below = 0 |TV + hysteresis above = 1
