b8
setting the maximum number of evaporation cycles between two drain cycles for
dilution step:1
The actual value used is internally calculated based on the value read for the conduc-
tivity of the water supply (the higher the conductivity, the lower the calculated value),
however if the calculated value is greater than b8, b8 will be used. If b8=0, it shall
be automatically set to 2 at fi rst heaters start-up and if conductivity measured in the
supply water is <= 100 μS/cm, or at 5.

available for measuring the diff erence between the value displayed d3 and the actual
steam production.
Example of use:
d3= 10 kg/h and bb= +10% changes d3 to 11 kg/h (= 10 kg/h + 10%)
