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).
