Parameter setting
Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D
• Version: 10.09.2018 • Technical changes and errors excepted.
The behaviour of the switching output on release is dependent on the value of the pa-
rameter "Switching output sends" (see "Switching output")
6.5.
Temperature PI control
Activate the control if you want to use it.
General control
Set, in which cases
setpoint values and extension time
received via object are to
be retained. The parameter is only taken into consideration if the setting via object is
activated below. Please note that the setting "After power supply restoration and pro-
gramming" should not be used for the initial start-up, as the factory settings are always
used until the 1st communication (setting via objects is ignored).
Analysis of the blocking object
• At value 1: block | At value 0: release
• At value 0: block | At value 1: release

Behaviour of the switching output
On block
• Do not send message
• send 0
• send 1
On release
(with 2 seconds release delay)
[Dependent on the "Switching output
sends" setting]
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
