Parameter setting
Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D
• Version: 10.09.2018 • Technical changes and errors excepted.
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
Set, in which cases
setpoint values
received via object are to be retained. Please note
that the setting "After power supply restoration and programming" should not be used
for the initial start-up, as the factory settings are always used until the first communi-
cation (setting via objects is ignored).
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 ta-
ken into service, the last communicated setpoint value can be used. Basically, an air
humidity range is specified in which the setpoint value can be changed (
object value
limit
).
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.
