Lamborghini Caloreclima 55 PM/2-E Manuel D'installation Et D'entretien page 57

CALIBRATION OF MINIMUM GAS PRESSURE SWITCH
The function of the minimum gas pressure switch is to prevent the burner from starting or to stop it when it is
running if the gas pressure is not at the minimum required; it must be calibrated to 40% lower than the gas
pressure value when operating at maximum flow rate.
CALIBRATION OF MAXIMUM GAS PRESSURE SWITCH (ON REQUEST)
The maximum gas pressure switch serves to put the burner in blocking mode if the gas pressure exceeds the
pre-set value. Set the combustion head pressure to 15% more than the nominal capacity required at the time
of installation.
