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] Maximum temp (heating)
37°C~80°C (default: 80°C)
[A.3.1.1.2.1] [9-01] Minimum temp (heating)
15°C~37°C (default: 25°C)
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] Maximum temp (heating)
37°C~80°C (default: 80°C)
[A.3.1.2.2.1] [9-05] Minimum temp (heating)
15°C~37°C (default: 25°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
N/A [9-04] 1~4°C (default: 1°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
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).

# Code
N/A [D-03]
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 (refer to the design and
selection of the heat emitters) between the desired leaving water
temperature and the desired room temperature.
# Code
N/A [8-06]
Temperature ranges (room temperature)
ONLY applicable in room thermostat control. In order to save energy
by preventing overheating the room, you can limit the range of the
room temperature.
NOTICE
When adjusting the room temperature ranges, all desired
room temperatures are also adjusted to guarantee they are
between the limits.

# Code
[A.3.2.4] N/A
Room temperature hysteresis
ONLY applicable in case of room thermostat control. The hysteresis
band around the desired room temperature is settable. It is
recommended NOT to change the room temperature hysteresis as it
is set for an optimal use of the system.
