Parameter setting
Sensor Sewi KNX TH-L-Pr
• Version: 17.11.2016 • Technical changes and errors excepted.
If the block is activated, define specifications here for the behaviour of the output when
blocked.
The behaviour of the switching output on release is dependent on the value of the pa-
rameter "Switching output sends" (see "Switching output")
6.14. Humidity PI control
If you activate humidity control, you can use the following settings to define control ty-
pe, setpoint values, and humidification and dehumidification.
General control
Sensor Sewi KNX TH-L-Pr
can be used to control one- or two-level dehumidification
or combined humidification/dehumidification.
Configure a block for the humidity control using the blocking object.
Use switching output block
No • Yes
Analysis of the blocking object
• At value 1: block | At value 0: release
• At value 0: block | At value 1: release
Blocking object value before first communi-
cation
0 • 1
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
Use humidity control
No • Yes
Type of control
• One-level dehumidification
• Two-level dehumidification
• Humidification and dehumidification
