INFORMATION
The real desired tank temperature is defined by the
selected absolute desired tank temperature and the
number of persons + 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] [6-0E] 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.
The maximum temperature is NOT
applicable during disinfection function.
See disinfection function.
▪ [E-06]=0 (no tank installed): 40~65°C
(default: 65°C)
▪ [E-06]=1 (tank installed): 40~75°C
(default: 75°C)

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 the highest 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 desired shift values or the absolute desired leaving water
temperature should be specified.
NOTICE
The preset leaving water temperatures are ONLY
applicable for the main zone, as the schedule for the
additional zone consists of On/OFF actions.
NOTICE
Select preset leaving water temperatures in accordance
with the design and selected heat emitters to ensure the
balance between desired room and leaving water
temperatures.
# Code Description
Preset leaving water temperature for the main leaving water
temperature zone in case of NOT weather dependent
[7.4.2.1] [8-09] Comfort (heating)
[9-01]~[9-00] (default: 45°C)
[7.4.2.2] [8-0A] Eco (heating)
[9-01]~[9-00] (default: 40°C)
[7.4.2.3] [8-07] Comfort (cooling)
[9-03]~[9-02] (default: 18°C)
[7.4.2.4] [8-08] Eco (cooling)
[9-03]~[9-02] (default: 20°C)
Preset leaving water temperature (shift value) for the main leaving
water temperature zone in case of weather dependent
[7.4.2.5] N/A Comfort (heating)
−10~+10°C (default: 0°C)
[7.4.2.6] N/A Eco (heating)
−10~+10°C (default: −2°C)
[7.4.2.7] N/A Comfort (cooling)
−10~+10°C (default: 0°C)
[7.4.2.8] N/A Eco (cooling)
−10~+10°C (default: +2°C)
Temperature ranges (leaving water temperatures)
The purpose of this setting is to prevent selecting a wrong (i.e. too
hot or too cold) leaving water temperature. Therefore the available
desired heating temperature range and desired cooling temperature
range can be configured.
NOTICE
In case of a floor heating application it is important to limit
the:
▪ maximum leaving water temperature at heating
operation according to the specifications of the floor
heating installation.
▪ the minimum leaving water temperature at cooling
operation to 18~20°C to prevent condensation on the
floor.
NOTICE
▪ When adjusting the leaving water temperature ranges,
all desired leaving water temperatures are also
adjusted to guarantee they are between the limits.
▪ Always balance between the desired leaving water
temperature with the desired room temperature and/or
the capacity (according to the design and selection of
the heat emitters). The desired leaving water
temperature is the result of several settings (preset
values, shift values, weather dependent curves,
modulation). As a result, too high or too low leaving
water temperatures could occur which lead to
overtemperatures or capacity shortage. By limiting the
leaving water temperature range to adequate values
(depending on the heat emitter), such situations can be
avoided.
