Low pressure lock-out
When this lock-out occurs,
“E19”
alarm code will appear on the digital display. The burner and the
boiler's circulation pumps will switch off, cutting off the heating and water flow to the installation.
The blockage occurs when the boiler pressure drops below 0.5 bar, preventing it from working when
the installation is drained of water, either due to a leak or due to maintenance operations. To unblock
this alarm, the installation must be filled again (see "Filling the boiler"), until a pressure between 1 and
1.5 bar is displayed in the "water pressure" parameter of the "User Menu".
