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).
# Code
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]
[A.3.1.1.2.1] [9-01]
Leaving water temperature range for the additional leaving water temperature
zone (= the leaving water temperature zone with the highest leaving water
temperature in heating operation and the lowest leaving water temperature in
cooling operation)
[A.3.1.2.2.2] [9-06]
[A.3.1.2.2.1] [9-05]
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.
