R32 Split series – Domestic hot water tank
4P680077-1 – 2021.11
WD curve
When weather-dependent operation is active the desired tank temperature is
determined automatically depending on the averaged outdoor temperature: low
outdoor temperatures will result in higher desired tank temperatures as the cold
water tap is colder and vice versa.
In case of Schedule only or Schedule + reheat domestic hot water
preparation, the storage comfort temperature is weather-dependent (according to
the weather-dependent curve), the storage economic and reheat temperature are
NOT weather-dependent.
In case of Reheat only domestic hot water preparation, the desired tank
temperature is weather-dependent (according to the weather-dependent curve).
During weather-dependent operation, the end-user cannot adjust the desired tank
temperature on the user interface. Also see "10.5 Weather-dependent
curve"[465].
