Parameter setting
Actuator KNX S1R-BA4-UP 24 V
• Version: 27.05.2020 • Technical changes and errors excepted.
Forced ventilation:
If forced ventilation is active ("use forced ventilation: Yes"), ventilation is started as
soon as the communication object "forced ventilation" = 1.
Warm supply air block:
The input object "warm supply air block" is linked with the output object of one or more
temperature sensors. The input object can be a 1bit object (smaller or larger than a
threshold value), as well as a 16bit object (measurement value indoor/outdoor or target
and actual value).
1bit input object:
Ventilation is allowed if the bit is 0 and blocked if the bit is 1.
16bit input object:
Ventilation is allowed if the outdoor measurement value is smaller than the indoor
measurement value+difference-hysteresis and blocked if the outdoor measurement
value is greater than or equal to the indoor measurement value+difference.
16bit input object (target/actual temperature):
For this function the target value and actual value (measurement values) are imported
from the 16bit object and evaluated.
Ventilation is allowed if the outdoor measurement value is smaller than the target
value+difference-hysteresis and blocked if the outdoor measurement value is greater
than or equal to the target value+difference.
