b7 control of the foam detection threshold (if set to 0 foam detection is disabled) % 0,…,100 50 I 23
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 rst heaters start-up and if conductivity measured in the
supply water is <= 100 µS/cm, or at 5.

b9 minimum time for passing from 0 to 100% of steam production min 0,…,100 0 I 24
bA percentage reduction in the duration of the water ll time % 20…100 100 I 34
bb
steam production value (step 0.1%)
it allows the user to “adjust” the value displayed by parameter d3, if there is a system
available for measuring the di 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%)
