In case of operating problems or trouble, the display flashes and the fault identification code appears
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore operation it is sufficient to press
the reset button (detail 6 - fig. 1) for 1 second or use the RESET on the remote timer control (optional) if installed; if the
boiler does not restart, it is necessary to, firstly, eliminate the fault.
Other faults cause temporary shutdowns (marked with the letter “F”) which are automatically reset as soon as the value
returns within the boiler's normal working range.

Make sure that the card is powered: using a digital multimeter, check for
the presence of supply voltage.
In case of no voltage, check the wiring.
If the voltage is sufficient ( Range 195 – 253 Vac ), check the fuse
(3.15AL@230VAC). The fuse is on the card. To reach it, see
fig. 20 and
fig. 48.
