The value communicated last shall be
maintained
• not
• after restoration of voltage
• after restoration of voltage and programming
(Do not use for first commissioning)
Start humidity threshold value in % rh
valid until 1.communication
(only if the value communicated last is “not”
maintained or “after restoration of voltage”)
0 … 100
Type of threshold change for humidity
• Absolute value
• Increment/decrement
Step size
(only with “Increment/decrement”)
1% • 2% • 5% • 10%
Hysteresis of the threshold value in %
0 … 50
Humidity switching output:
……………………………
Output is at
(TV = humidity threshold value)
• TV above = 1 | TV – Hyst. below = 0
• TV above = 0 | TV – Hyst. below = 1
• TV below = 1 | TV + Hyst. above = 0
• TV below = 0 | TV + Hyst. above = 1
Switching delay from 0 to 1
none • 1 s • 2 s • 5 s • 10 s • … • 2 h
Switching delay from 1 to 0
none • 1 s • 2 s • 5 s • 10 s • … • 2 h
Humidity 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
Send humidity switching output
in the cycle of
(only if sending “periodically”)
5 s • 10 s • 30 s • 1 min • … • 2 h
Blocking:
……………………………
Use block of the humidity switching output
No • Yes
Evaluation of the humidity blocking object
• if value 1: block | if value 0: release
• if value 0: block | if value 1: release
Value of the humidity blocking object
before 1. communication
0 • 1
Behaviour of humidity switching output
with blocking
• do not send telegram
• send 0
• send 1
The behaviour with release of the switching output depends on the value of the
parameter “Humidity switching output sends …” (see ”Humidity switching output”)
