Set the Aux. temperature averaging time parameter.

The Aux. temperature averaging time parameter defines the TM-Pt1000 temperature sensor measurement averaging time in seconds. It is defined as the length of the time window where WXT536 calculates the temperature average within the update interval window.

The following figure represents the temperature measurement averaging for measurement update interval (I) and averaging time (A).
