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.

Leaving water temperature: Modulation
To allow better matching of the heat pump capacity with the actual required
capacity, enable the leaving water temperature modulation. If modulation is
enabled, the unit calculates the leaving water temperature according to the
difference between desired and actual room temperature. As a result, the
heat pump will have less start/stop cycles and thus operate more economical.
If modulation is enabled, you can also set the maximum modulation of the leaving
water temperature. The maximum modulation is the value by which the desired
leaving water temperature is increased or lowered.
