# 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)
[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)
[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. This function is ONLY applicable in heating mode.
# Code
N/A [9-04]
INFORMATION
This overshoot temperature applies to the heat pump leaving water temperature.
Note that when the gas boiler is operating, there can be a 5°C overshoot over the
desired boiler 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 (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).
