Description of functioning states

Summer functioning mode without request in progress.
SUMMER
Boiler in stand-by for domestic hot water request.
Winter functioning mode without request in progress.
WINTER
Boiler in stand-by for domestic hot water or central heating request.
Domestic hot water mode in progress.
DHW ON
Boiler functioning, domestic hot water heating in progress.
Central heating mode in progress.
CH ON
Boiler functioning, central heating in progress.
Antifreeze mode in progress.
F3
Boiler functioning to restore the minimum safety temperature against boiler freezing.
CAR OFF Remote Control (Optional) off.
With domestic hot water priority disabled (indicator 15 off), the boiler only functions in room central heating mode for
duration of 1 hour, however keeping the domestic hot water at minimum temperature (20°C), after which the boiler
DHW OFF goes back to the normal functioning, previously set.
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 (see Super CAR instructions manual).
Postventilation in progress.
F4
Fan in function after a request for domestic hot water or central heating in order to evacuate residual flue gas.
Postcirculation in progress.
F5
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, the boiler functions all the same in central
P33 heating mode. (Can be activated through menu "M3". It allows you to activate the central heating even if the Remote

temperature for room central heating.
In the presence of the external probe (optional) replace the "SET" item.

The value that appears is the correction of the flow temperature with respect to the functioning curve set by the external
probe. See OFFSET on external probe graphics (Fig. 1-6).
System deaeration in progress.
F8
During this phase, which lasts 18 hours, the boiler circulator pump is started at preset intervals, thus allowing deaeration
of the central heating system.
Only in the case of use with Super CAR, does it allow to activate the anti-legionella function, which takes the temperature
