2 3 9 Setting
the Delta T
Circulation pump modulation
from 10 to 30 °C 20 to be set with operation of the circulation pump
in modulating mode
These parameters allow the ow and backow temperature dierence to be set, which determines whether the circulation
pump switches from low to high speed
E.g.: par
am. 239 = 20 and ∆T > 20°C- the circulation pump runs at high speed. If ∆T < 20 - 2°C the circulation pump runs at
low speed. The minimum waiting time for changing speed is 5 minutes.
