Sensors
The room temperature controller is equipped with three sensors:
•
temperature (1);
•
relative humidity (2).
Position of the sensors: temperature (1), relative humidity (2).
The temperature sensor (not to be seen in the drawing) is located under the plastic half-shell for the rockers’ mounting.
5.1
Temperature sensor
The integrated temperature sensor allows the measureming of the room temperature in the range from 0 °C
to +40 °C with a resolution of 0.1 °C. To keep into account significant environmental interferences such as
the proximity to heatsources, the installation on an outer wall, the chimney effect due to rising warm air
through the corrugated tube connected to the wall-mounting box, the measured value can be corrected by
means of a offset of ± 5 °C or, preferably, can be used a weighted average between two values of
temperature chosen from the following ones: value measured by the integrated sensor, value measured by a
temperature sensor connected to one of the inputs of the device, value received via bus from another KNX
device (such as ekinex pushbuttons).
5.2
Relative humidity sensor
The integrated relative humidity sensor allows the measuring of the relative humidity value in the room. The
measured value allows you to make an advanced room thermoregulation and enlarge the opportunities for a
safe operation of certain types of terminal equipments used for cooling. The measured value can also be
sent on the bus via the 114 (1 byte) and the 115 (2 bytes) Communication Objects.By means of a calculation
performed by the thermostat, on the bus can also be sent psychrometric values obtained from the combined
measurement of temperature and humidity, such as the dew-point temperature, as well as the index of
perceived temperature (only in summer mode).
