mode for duration of 1 hour, however keeping the domestic hot water at minimum temperature (20 °C),
after which the boiler goes back to the normal functioning, previously set.

With Remote Control (Optional) or room thermostat (TA) (Optional) in block mode, the boiler func-
tions all the same in CH mode (Can be activated using the "Customisations" menu, it allows to activate the
central heating even if the Remote Control or TA are out of service).
Reset attempts finished.
One hour must pass in order to acquire 1 attempt (See no ignition block).
Anomaly present with relative error code.
The boiler does not function (see troubleshooting paragraph).
During the rotation of the domestic hot water temperature selector switch, view the state of the adjust-
ment of the domestic hot water temperature in progress.
During rotation of the central heating selector switch, view the adjustment status of the boiler flow
temperature for room central heating.
In presence of the external probe (Optional) replace the "SET CH" item.
The value that appears is the correction of the flow temperature with respect to the functioning curve set
by the external probe.
System deaeration in progress.
During this phase, which lasts 18 hours, the boiler pump is started at pre-established intervals, thus al-
lowing deaeration of the heating system.
Only in the case of use with Super CAR, does it allow to activate the anti-legionella function, which
takes the temperature of the water in the storage tank to 65°C for 15 minutes (see Super CAR instruction
book).
