Hysteresis
The following ON hysteresis can be set.
Heat pump ON hysteresis
Applicable when domestic hot water preparation is reheat only. When the tank
temperature drops below the reheat temperature minus the heat pump ON
hysteresis temperature, the tank heats up to the reheat temperature.
The minimum ON temperature is 20°C, even if setpoint hysteresis is smaller than
20°C.
# Code
[5.9] [6-00]
Reheat hysteresis
Applicable when domestic hot water preparation is scheduled+reheat. When the
tank temperature drops below the reheat temperature minus the reheat hysteresis
temperature, the tank heats up to the reheat temperature.

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
preparation, the storage comfort temperature is weather dependent (according to
the weather dependent curve), the storage economic and reheat temperature are
NOT weather dependent.
Maximum:
The maximum temperature that users can select
for the domestic hot water. You can use this
setting to limit the temperature at the hot water
taps.
The maximum temperature is NOT applicable
during disinfection function. See disinfection
function.
