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.

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).

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.
Minimum temp (heating)
15°C~37°C
Maximum temp (cooling)
18°C~22°C
Minimum temp (cooling)
5°C~18°C
1°C~4°C
