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.
Range: 40°C~80°C (in steps of 1°C;
default value: 60°C).
The maximum temperature is NOT
applicable during disinfection function.
See disinfection function.

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.

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.
Example:
Set the minimum leaving water temperature to 28°C to
avoid NOT to be able to heat up the room: leaving water
temperatures MUST be sufficiently higher than the room
temperatures (in heating).
