Structure of Actuator KNX S-B4T-UP 230 V AC - IQmarket

Dawn control / time control
Use dawn and time control
• No
• only dawn control
• only time control
• both (OR gating)
If dawn control or time control or both are used:
Type of dawn input object
1 Bit • 16 Bit
If “Type of dawn input object 16 bit“ has been selected:
Type of dawn input object
16 Bit
Dawn threshold value in lux 1 … 1000
Switching delay
1 minute
Send current dawn status
No • Yes
Time control is accomplished by a communication object.
Release of indoor temperature
Use indoor temperature release
No • Yes
If “Use indoor temperature release: Yes“ has been selected:
Type of input object
1 bit • 16 bit • 16 bit target/actual temperature
If “Type of input object 1 bit“ has been selected:
Shading is permitted if bit is 1, and it is blocked if bit is 0.
If “Type of input object 16 bit“ has been selected:
Shading is permitted if the measured value is larger than or equal to the threshold, and
it is blocked if the measured value is smaller than the threshold minus hysteresis.
Threshold in 0.1°C -300 … 800
Hysteresis in 0.1°C 1 … 100
Send current block status
No • Yes
If “Type of input object 16 bit target/actual temperature“ has been selected:
Shading is permitted if the measured value is larger than or equal to the target value
plus the target-actual-difference, and it is blocked if the measured value is smaller than
the target value plus the target-actual-difference minus hysteresis.
The target value is provided by the communication object.
Target-actual difference in 0.1 °C 1 … 100
Hysteresis in 0.1°C 1 … 100
Send current block status
No • Yes
Shading automatic
Use shading automatic
No • Yes
