2. The hot water volumes are based on a mean hot water temperature of 40°C
at a flow of 15 l/min. Cold water inlet temperature 10°C. In contrast to bath tub
operation, the outlet temperature of 40 °C is not undershot at the hot water
extraction point in shower operation.

Different hot water sensors must be used depending on the
type of heat pump manager present in the heat pump
system.
