Temperature Sensor KNX T-UN
• Version: 27.01.2020 • Technical changes and errors excepted.
Threshold value setpoint using a communications object:
Beforehand, enter how the threshold value will 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 un-
til the first call with of a new threshold value. For units which have already been taken
into service, the last communicated threshold value can be used. Basically, a temper-
ature 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.
Temperature switch 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.
Temperature threshold value specification

Parameter •
Communications objects
The last communicated value should
• never be retained
• be retained after power restoration
• be retained after power restoration and
programming.

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