Explanations
The higher the value, the greater the influence of the
room temperature on the set flow temperature of the
heating circuit (heating curve). Operation with room
temperature hook-up must be set for the heating cir-
cuit (parameter 936.6). Change value for heating cir-
cuit with mixer only.
For a sample calculation, see chapter "Heating curve"
in the "Function description"
