Parameter setting
Sensor KNX AQS/TH-UP Touch
• Version: 23.10.2018 • Technical changes and errors excepted.
Setpoint value setting using parameters:
Set the setpoint value directly.
Setpoint value setting via communication object:
Enter, how the setpoint 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 setpoint value must be defined which is valid until the
first communication of a new setpoint value. For units which have already been taken
into service, the last communicated setpoint value can be used. Basically, an air humid-
ity range is given in which the setpoint value can be changed (object value limit).
A set setpoint 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.
Ventilation control
Depending on the control mode, one and/or two setting sections for the ventilation
stages are displayed.
For two-stage ventilation, the setpoint value difference between the two stages must
be defined, i.e. the setpoint value which, when exceeded, triggers the switch to the 2nd
level.
