Actual Temperature Receipt; Dew Point Status Receipt - ABB i-bus VC/S 4 1 Series Product Manual

ABB i-bus® KNX PARAMETERS
7.4.41

Actual temperature receipt

This parameter is used to define how the controller receives the actual temperature.
If a temperature sensor is not connected to any of the inputs, the controller changes to safety mode.
If several inputs are set as temperature sensors, a mean value is formed from the measured values and
is used as the actual temperature value.

Dew point status receipt

This parameter is used to define how the controller receives the dew point status.
If no input is set as the dew point sensor, the controller interprets the function as being deactivated.
If several inputs are set as dew point sensors, they are logically OR-linked. The controller reacts as
soon as one of the inputs sends the status "Dew point reached".
Option
Deactivated
Via physical device input
Via group object

Note
The controller checks which device input is parameterized as a temperature sensor. The measured
actual temperature is included in control.
The actual temperature is received via max. two group objects. The received values are weighted.
The following dependent parameters are shown:
Number of group objects Actual temperature
•
The actual temperature can be received via a device input and/or via group objects. The values
measured on the inputs and received via the bus (ABB i-bus® KNX) are weighted.
The following dependent parameters are shown:
Number of group objects Actual temperature

• Weighting of internal measurement
• Weighting of external measurement 1

Note
The controller ignores the dew point status.
The controller checks which device input is parameterized as a dew point sensor. The status of the
connected dew point sensor is included in control.
The dew point status is received via the group object
