Preset values make it easy to use the same value in the schedule. If
you later want to change the value, you only have to do it in 1 place
(see also operation manual and/or user reference guide).
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.
# Code
[7.4.3.1] [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).
# Code
[7.4.3.2] [6-0B] 30°C~min(50, [6‑0E])°C (default: 45°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
[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
[7.4.3.3] [6-0C] 30°C~min(50, [6‑0E])°C (default: 45°C)
Reheat hysteresis
Only applicable when domestic hot water preparation is scheduled +
reheat.
# Code
N/A [6-08] 2°C~20°C (default: 10°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.

Limits on heat pump operation
In domestic hot water operation, following hysteresis values can be
set for the heat pump operation:

the heat pump ON temperature.
