• from software 3.1 • Status: 24.03.2016 • Technical changes reserved. Errors reserved.
The behaviour of the switching output on release is dependent on the value of the pa-
rameter "Switching output sends" (see "Switching output")
4.5.
CO2 PI control
If you activate air quality control, you can use the following settings to define control
type, target values, and ventilation.
General control
The
Sensor KNX AQS-UP basic
can be used to control one or two-stage ventilation.
Configure a block for the ventilation control using the blocking object.
Determine when the current control settings are to be sent to the bus. Periodic trans-
mission is safer if 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.
Switching output sends on change
• Do not send message
• Send switching output status
Switching output sends on change to 1
• Do not send message
• If switching output = 1
send 1
Switching output sends on change to 0
• Do not send message
• If switching output = 0
send 0
Switching output sends on change and
periodically
Send switching output status
Switching output sends on change to 1 and
periodically
If switching output = 1
send 1
Switching output sends on change to 0 and
periodically
If switching output = 0
send 0
