31 Parameter setting
Sensor KNX AQS/TH-B-UP • as of software 3.1 • Version: 01.03.2017 • Technical changes and errors excepted.
On level 2, the set point deviation between the two levels must furthermore be deter-
mined, i. e. the lowest set point value from which the 2nd level is then added (when
values exceed this set point).
PI control with control parameters:
This setting allows individual input of the parameters for PI control.
Determine the deviation from the set point value which reaches maximum variable val-
ue, i. e. the point at which maximum heating power is activated.
The reset time shows how quickly the controls react to deviations from the set point
value. In case of a short reset time, the controls react with a fast increase of the varia-
ble. In case of a long reset time, the controls react somewhat more gently and needs
longer until the necessary variable for the set point deviation is reached.
You should set the time appropriate to the heating system at this point (note manufac-
turer instructions).
Now determine what should be transmitted when the control is blocked. Set a value
greater 0 (=OFF) to receive a basic heating level, e.g. for floor heating.
Upon release, the control variable follows the rule again.
In case of a common variable for heating and cooling, 0 is always transmitted as a fixed
value.
PI control with predetermined application:
This setting provides fixed parameters for frequent applications.
