Description of functioning states
Summer functioning mode without request in progress.
Boiler in stand-by for domestic hot water request.
Winter functioning mode without request in progress.
Boiler in stand-by for domestic hot water or central heating request.
Domestic hot water mode in progress.
Boiler functioning, domestic hot water heating in progress.
Central heating mode in progress.
Boiler functioning, central heating in progress.
Anti-freeze mode in progress.
Boiler functioning to restore the minimum safety temperature against boiler freezing.
Remote Control (Optional) off.
In the case of use with Super CAR in concomitance with the functioning period in reduced D.H.W. Timer
mode, DHW OFF will appear on the display and indicators 15 and 2 switch off.
Postventilation in progress.
Fan in function after a request for domestic hot water or central heating in order to evacuate residual fumes.
Postcirculation in progress.
Pump in function after a request for domestic hot water or central heating in order to cool the primary circuit.
With Remote Control (Optional) or room thermostat (TA) (Optional) in block mode, the boiler functions 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 adjustment 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 allowing
deaeration of the heating system.
Only in the case of use with Super CAR remote control, 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 remote control instruction book).
Solar function.
The solar function is activated to control just the pump for DHW.
When the solar pump is powered, the display will show SOLAR', which may alternate with other function
texts in progress.
The solar pump functions permanently.
The solar pump stays off.
