The burner is completely switched off (0 min ON) if, in the worst case (300 or 450 l/h), the
flow and return temperature derivative values are below 0.5°C/seconds, in which case the
reference error is E84.
Important. Errors E81, 82, 83 and 84 are not displayed by default, on the boiler screen,
they are only recorded in the super-technical parameters memory (from P01 to P05).
During intervention of the water flow control and subsequent switching on and off of the
burner, the pump remains powered on.
