If the output of the solar plant is greater than 80% of the nominal output (ID 08-071 factory setting 100%), when
the tank reference temperature (08-062) is reached, the burner block is activated for 18 hours.
If the tank temperature drops below the tank reference temperature less reference value reduction for high solar
yield (08-072), the block is deactivated.

At a high solar yield, the reference value
is reduced by the difference (08-072).
