# Code Description
N/A [9-04] 1°C~4°C
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).

Leaving water temperature maximum modulation
ONLY applicable in room thermostat control and when modulation is enabled. The
maximum modulation (=variance) on the desired leaving water temperature
decided on the difference between the actual and desired room temperature, e.g.
3°C modulation means the desired leaving water temperature can be increased or
lowered by 3°C. Increasing the modulation results in better performance (less On/
OFF, faster heat up), but note that depending on the heat emitter, there MUST
ALWAYS be a balance (see the design and selection of the heat emitters) between
the desired leaving water temperature and the desired room temperature.

Temperature ranges (room temperature)
ONLY applicable in room thermostat control. In order to save energy by preventing
overheating or undercooling the room, you can limit the range of the room
temperature.
