[1] - Weather-dependent set value regulation
The target settings in the parameter settings determine the specified values to be attained in weather-dependent operation.
If the "Weather-dependent set value regulation" is active, the flow temperature is determined automatically depending on the
outside temperature: Colder outside temperatures result in warmer water and vice versa. During "Weather-dependent set value
regulation", the user can adjust the target flow temperature by a maximum of 5 °C up or down.
The following setting options are available:
– [1-00] Lowest ambient temperature (Lo_A): Lowest outside temperature.
– [1-01] Highest ambient temperature (Hi_A): Highest outside temperature.
– [1-02] Target value at lowest ambient temperature:
Target temperature at water outlet of the interior heat pump unit (HPSU compact) if the outside temperature is equal to or
falls below the lowest ambient temperature (Lo_A).
– [1-03] Target value at highest ambient temperature:
Target temperature at water outlet of the interior heat pump unit (HPSU compact) if the outside temperature is equal to or
increases above the highest ambient temperature (Hi_A).
