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.
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) leaving water temperature. Thereto the available desired
heating 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.
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).

Leaving water temperature overshoot temperature
This function defines how much the water temperature may rise
above the desired leaving water temperature before the compressor
stops. The compressor will startup again when the leaving water
temperature drops below the desired leaving water temperature.

Leaving water temperature compensation around 0°C
In heating operation, the desired leaving water temperature is locally
increased around an outdoor temperature of 0°C. This
compensation can be selected when using an absolute or a weather
dependent desired temperature, this compensation can be selected
(see illustration below). Use this setting to compensate for possible
heat losses of the building when the outdoor temperature is around
0°C (e.g. in cold region countries).
