One of the two symbols flashing means that the water
temperature (hot or cold) is not sufficient, and stops
the fan until the temperature reaches a level suitable for
reaching the required temperature.
If after switching the power on the board detects the H2 probe, start-up occurs in normal conditions with the
minimum and maximum thresholds.
The board also has a function when there is no H2 probe,
in such cases the fan stop thresholds are ignored.
When the control is in this operating mode, anti freezing is
in any case guaranteed. If the ambient temperature drops below 5°C, the solinoid output is opened.
The adjustment range is from 16 to 28°C in intervals of 1
°C, but out-of-range values are also accepted, from 5°C
to 40°C (unless in auto mode). Only set these values for brief periods, and then set a
intermediate value.
