Daikin Altherma – Low temperature split
4P384974-1 – 2015.01
Storage comfort: When programming the schedule, you can make
use of the tank temperatures set as preset values. The tank will then
heat up until these setpoint temperatures have been reached.
Additionally, a storage stop can be programmed. This feature puts a
stop to tank heating even if the setpoint has NOT been reached.
Only program a storage stop when tank heating is absolutely
undesirable.

[6-0A]
30°C~[6‑0E]°C (default: 60°C)
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).

Reheat: The desired reheat tank temperature is used:
▪ in reheat mode or 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.

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 screheat 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.

N/A
Weather dependent desired tank
temperature is:
▪ Fixed (default): disabled. All desired
tank temperature are NOT weather
dependent.
▪ Weather dep.: enabled. In scheduled
or
screheat
mode,
the
storage

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.
