If after switching the power on the board
detects the H2 probe, start-up occurs in normal
conditions with the minimum water temperature
when heating (30°C) and maximum when
cooling (20°C).
The board also has a function when there is no
probe, in such cases the fan stop minimum and
maximum thresholds are ignored.
