INFORMATION
It is recommended NOT to use the selection of ([6­0D]=0,
[A.4.1] Domestic hot water Setpoint mode=Reheat only).
The risk of space heating capacity shortage/comfort
problems is significant (in case of frequent domestic hot
water operation, frequent and long space heating
interruption will happen).
Readout the desired tank temperature
The desired tank temperature is displayed on the user interface. By
the following settings, you can configure the way the tank
temperature is displayed:
▪ by its numerical value
▪ by an equivalent.
Use the numerical value in case the understanding of tank
temperature is clear for the customer. On the user interface the
customer can set the desired tank temperature per 1°C. For
customers with less feeling about tank temperatures, choose display
by equivalent number of people. They will set the desired tank
temperature by indicating their domestic hot water consumption as a
number of people.
As installer, you configure the conversion between the equivalent
domestic hot water consumption per person at 1 heat­up cycle and
the real desired tank temperature. Please take into account the
installed tank size. Additionally, using the graphical display, the
customer is made aware about the amount of consumed domestic
hot water.
# Code Description
[A.4.3.1] N/A How is the tank temperature to be
displayed on the user interface?
▪ As temperature.
60°C
▪ As graphic: The temperature has to be
displayed as available hot water for
x persons. If you choose this, you also
have to configure which number
equals
which temperature under
[A.4.3.2.1]~[A.4.3.2.6]:
4
[A.4.3.2.1] N/A 1 person
The absolute desired tank temperature
for 1 person. 30~80°C (default: 42°C)
[A.4.3.2.2] N/A 2 persons
The increment of the desired tank
temperature for 2 persons compared to 1
person. 0~20°C (default: 6°C)
[A.4.3.2.3] N/A 3 persons
The increment of the desired tank
temperature for 3 persons compared to 2
persons. 0~20°C (default: 15°C)
[A.4.3.2.4] N/A 4 persons
The increment of the desired tank
temperature for 4 persons compared to 3
persons. 0~20°C (default: 17°C)
[A.4.3.2.5] N/A 5 persons
The increment of the desired tank
temperature for 5 persons compared to 4
persons. 0~20°C (default: 1°C)
[A.4.3.2.6] N/A 6 persons
The increment of the desired tank
temperature for 6 persons compared to 5
persons. 0~20°C (default: 1°C)
INFORMATION
The real desired tank temperature is defined by the
selected absolute desired tank temperature and the
number of p selected increment value(s).
Example: 3 persons (default settings)
Real desired tank temperature=[A.4.3.2.1] + [A.4.3.2.2] +
[A.4.3.2.3]
Real desired tank temperature=42+6+15=63°C.
Maximum tank temperature
The maximum temperature that users can select for the domestic
hot water. You can use this setting to limit the temperatures at the
hot water taps.
INFORMATION
During disinfection of the domestic hot water tank, the tank
temperature can exceed this maximum temperature.
INFORMATION
Limit the maximum hot water temperature according to the
applicable legislation.
# Code Description
[A.4.5] [6­0E] Maximum setpoint
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.
If
▪ [E­07]=0: N/A
▪ [E­07]=1: 40~60°C (default: 60°C)
The maximum temperature is NOT
applicable during disinfection function.
See disinfection function.

# Code Description
[6.3.2] N/A Number that users can call in case of
problems.

Advanced configuration/
optimization
8.3.1
Space heating operation: advanced
Preset leaving water temperature
You can define preset leaving water temperatures:
▪ economic (denotes the desired leaving water temperature which
results in the lowest energy consumption)
▪ comfort (denotes the desired leaving water temperature which
results in a higher comfort but also a higher energy consumption).
Preset values make it easy to use the same value in the schedule or
to adjust the desired leaving water temperature according to the
room temperature (see modulation). If you later want to change the
value, you only have to do it in one place. Depending on whether the
desired leaving water temperature is weather dependent or not, the
absolute desired leaving water temperature should be specified or
the desired shift values.
