Control logic for the compensation set
The ANZ units are equipped with the function of self-compensation of the heat-produced water set, depending on the outside
temperature.
rL: outside temperature at start of compensation
r3: minimum temperature of the return water at rL
rF: maximum variation of the water temperature; where r3+rF = maximum temperature of return water
rE: incline of the water curve. Refers to the example below
