Parameter setting
Sensor KNX AQS/TH-B-UP
• as of software 3.1 • Version: 01.03.2017 • Technical changes and errors excepted.
Threshold value setpoint using parameter:
Set the threshold values and hysteresis directly.
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 1st communication of 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.
