[1] - Weather-dependent target value regulation
The target settings in the parameter settings determine the specified values to be attained in weather-dependent operation.
If the "Weather-dependent target value regulation" is active, the water temperature is determined automatically depending on
the outside temperature: Colder outside temperatures result in warmer water and vice versa. During "Weather-dependent target
value regulation" , the user can adjust the target water 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 Indoor Module (RKHB) 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 Indoor Module (RKHB) if the outside temperature is equal to or increases above
the highest ambient temperature (Hi_A).

NOTE:
– For colder outside temperatures (Lo_A), the value Lo_Ti must be higher that the value Hi_Ti, as hotter
water is required.
– With warmer outside temperatures (Hi_A) the value Hi_Ti must be lower that the value Lo_Ti, as less hot
water is required.
