5.14. CO2 PI-control
If you activate air quality control, you can use the following settings to define control
type, setpoint values, and ventilation.
General control
The
Sensor KNX AQS/TH-UP Touch
can be used to control one or two-stage venti-
lation.
Configure a block for the ventilation control using the blocking object.
Specify when the current control variables are to be sent to the bus. Periodic sending
is safer, in case a message does not reach a recipient. You may also set up periodic
monitoring using an actuator with this setting.
The status object shows the current status of the output variable (0 = OFF, >0 = ON) and
can for example be used for visualisation.
Controller setpoint
The setpoint values can be set directly in the application program using parameters, or
be defined via the bus using a communication object.
