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).
# Code Description
Leaving water temperature range for the main leaving water
temperature zone (= the leaving water temperature zone with the
lowest leaving water temperature in heating operation and the
highest leaving water temperature in cooling operation)
[A.3.1.1.2.2] [9-00] Maximum temp (heating)
37°C~55°C (default: 55°C)

5°C~18°C (default: 5°C)
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.
This function is ONLY applicable in heating mode.
# Code Description
N/A [9-04] 1°C~4°C (default: 1°C)
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 (see illustration below). Use this
setting to compensate for possible heat losses of the building due to
the evaporation of melted ice or snow (e.g. in cold region countries).
