9.3 Weighted temperature value
The
Weighted temperature value
folder appears only if two sensors for measuring the room temperature are enabled
and includes the following parameters:
•
Relative weight
•
Minimum change of value to send [K]
•
Cyclic sending interval

About weighted temperature
The device allows the acquisition of the room temperature in two ways:
1)
from the temperature sensor integrated in the device;
2)
via bus from another KNX device, e.g. from an ekinex pushbutton (External sensors (from bus) Room
temperature = enabled);
To optimize or correct the room temperature regulation in special cases (in large rooms, in presence of strong
asymmetry of the temperature distribution, when the installation of the device is in a position not suitable, etc.), the
device can then use a weighted average between two temperature values. The weights are assigned by the
parameter
Relative weight
that assigns a ratio of the two values
