Leaving water temperature: Delta T source
The Delta T is the required temperature difference between entering
and leaving water. This applies to both temperature zones. Change
the value of Delta T if another minimum temperature difference is
required for the good operation of the heat emitters in heating or
cooling mode.
# Code Description
[A.3.1.3.1] [1-0B] Delta T for heating
Range: 3°C~10°C
[A.3.1.3.2] [1-0D] Delta T for cooling
Range: 3°C~10°C
