Daikin Altherma hybrid heat pump

Storage eco
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).
# Code Description
[7.4.3.2] [6-0B] 30°C~min(50, [6‑0E])°C (default: 50°C)
Reheat
The desired reheat tank temperature is used:
▪ in reheat mode of scheduled + reheat mode: The guaranteed minimum tank
temperature is set by T
HP OFF
–[6‑08], which is either [6‑0C] or the weather-
dependent setpoint, minus the reheat hysteresis. If the tank temperature drops
below this value, the tank is heated up.
# Code Description
[7.4.3.3] [6-0C] 30°C~min(50, [6‑0E])°C (default: 50°C)
Reheat hysteresis
Only applicable when domestic hot water preparation is scheduled + reheat.
# Code Description
N/A [6-08] 2°C~20°C (default: 5°C )
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.
# Code Description
[A.4.6] N/A Desired temperature mode:
▪ Fixed (default): disabled. All desired tank
temperature are NOT weather-dependent.
▪ Weather dep.: enabled. In scheduled or
scheduled+reheat mode, the storage comfort
temperature is weather-dependent. Storage
economic and reheat temperatures are NOT
weather-dependent. In reheat mode, the
desired tank temperature is weather-
dependent.
Note: When the displayed tank temperature is
weather-dependent, it cannot be adjusted on
the user interface.
