Controls how fast the actual return temperature adapts to the
desired return temperature limitation.
Adjust the time constant for the return limitation.
The setting will eliminate the difference
between the acceptable and the actual return
temperature.
The difference is integrated to adjust the desired
flow temperature.
OFF: The desired flow temperature will not be
adjusted any further.
