3.14 SOLAR PANELS COUPLING FUNCTION
e device is set up to receive pre-heated water from a system of solar panels up to a maximum temperature of 65°C. In any case, it is al-
ways necessary to install a mixing valve on the hydraulic circuit upstream of the device, on the cold water inlet.
For good functioning of the boiler; the temperature selected on the solar valve must be 5 °C greater with respect to the tempera-
ture selected on the boiler control panel.
In this condition, parameter t2 (DHW thermostat) must be set at “1” and parameter t3 (solar delay time) must be set for a period that is
sucient to receive water from a storage tank located upstream of the boiler. e greater the distance from the storage tank, the longer the
stand-by time to be set.
3.15 “CHIMNEY SWEEP” FUNCTION
When activated, this function forces the boiler to variable output for 15 minutes.
In this state, all adjustments are excluded and the safety thermostat and the limit thermostat functions remain active. To activate the
chimney sweep function, press the “ ” button until activation of the function in the absence of DHW requests.
Its activation on the boiler display is conrmed by the indicators ashing at the same time ( , ), while on the CAR
V2
(optional) it is
reported as “ERR>07”.
is function allows the technician to check the combustion parameters.
Once the function is activated, it is possible to select whether to make the check in C.H. status or D.H.W. status by opening any hot water
cock adjusting the power via the buttons ( ).
e maximum power than can be supplied (99 %) is relative to the power set by parameter “P2” (Par. 3.13).
e central heating or D.H.W. operating mode is displayed by the relative symbols or .
Aer the checks, deactivate the function by switching the boiler o and starting it again using “ ”.
e boiler needs a certain amount of time to stabilise itself before carrying out a combustion parameters check. It is thus neces-
sary to wait for the boiler to carry out a self-diagnosis test, which is signalled by the ( ) ashing symbol. Once the symbol
stops ashing, it is possible to check the combustion parameters.
3.16 PUMP ANTIBLOCK FUNCTION
e appliance has a function that starts up the pump at least once every 24 hours for 30 seconds in order to reduce the risk of the pump
locking up due to prolonged inactivity.
3.17 THREEWAY ANTIBLOCK SYSTEM
In both pase "Domestic Hot Water" and "Domestic Hot Water-Central Heating", the appliance has a function that activates the motorised
3-way unit 24 hours aer the last time it operated by running a complete cycle in order to reduce the risk of the 3-way blocking due to pro-
longed inactivity.
3.18 RADIATORS ANTIFREEZE FUNCTION
If the system return water is below 4°C, the appliance starts up until reaching 42°C.
3.19 P.C.B. PERIODICAL SELFCHECK
During functioning in Central heating mode or with appliance in Standby, the function activates every 18 hours aer the last appliance
check/power supply. In case of functioning in domestic hot water mode the self-check starts within 10 minutes aer the end of the with-
drawing in progress, for duration of approx. 10 seconds.
During the self-check, the appliance remains o. Warnings included.
