Parameter settings
Interface KNX B8-TH
• Version: 24.08.2016 • Technical changes and errors excepted.
Set the
hysteresis
independently of the type of threshold value setting.
Switching output
Set the behaviour of the switching output when a threshold value is exceeded/under-
cut. The output switching delay can be set using objects or directly as a parameter.
Blocking
The switching output can be blocked using an object.
Set the
output behaviour during and after blocking
.
Object value limit (max)
in 0.1°C
-300…800
Type of threshold change
Absolute value • Increase/decrease
Step size
(upon increase/decrease change)
0.1°C • ... • 5°C
Hysteresis setting
in % • absolute
Hystereis in 0.1°
0...1100; 50
Hysteresis in % of the threshold value
0 … 50; 20
When the following conditions apply, the
output is
(TV = Threshold value)
• TV above = 1 | TV - Hyst. below = 0
• TV above = 0 | TV - Hyst. below = 1
• TV below = 1 |TV + hysteresis above = 0
• TV below = 0 |TV + hysteresis above = 1
Delays can be set via objects
(in seconds)
No • Yes
Switching delay from 0 to 1
(if delay is adjustable via objects: valid until
1st communication)
None • 1 s • 2 s • 5 s • 10 s • … • 2 h
Switching delay from 1 to 0
(if delay is adjustable via objects: valid until
1st communication)
None • 1 s • 2 s • 5 s • 10 s • … • 2 h
Switching output sends
• on change
• on change to 1
• on change to 0
• on change and periodically
• on change to 1 and periodically
• on change to 0 and periodically
Cycle
(is only sent if periodically is selected)
5 sec • 10 sec • 30 sec… • 2 hrs
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 call
0 • 1
