The storage economic temperature denotes the lower desired tank
temperature. It is the desired temperature when a storage economic
action is scheduled (preferably during day).

Reheat
The desired reheat tank temperature is used:
▪ in reheat mode or scheduled + reheat mode: The guaranteed
minimum tank temperature is set by T
[6‑0C] or the weather dependent setpoint, minus the reheat
hysteresis. If the tank temperature drops below this value, the tank
is heated up.

Weather dependent
The weather dependent installer settings define the parameters for
the weather dependent operation of the unit. 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 scheduled or scheduled+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.
