The "REC PLUS" software activates the heating of the water within the time and amounts determined automati-
cally by the product itself according to user consumption. During the day, when no water is drawn, the product
still guarantees a reserve of hot water.
Activate the "REC" function by pressing the relevant key that lights up green. Two operating modes are pos-
sible:
1) Manual adjustment of the temperature (see the "Adjusting the temperature and activating the functions of
the device" paragraph): the manual mode is accessed with the REC button off. In this mode, the product
continues to note the user's energy demand without adjusting the temperature selected by the user. Press
the "REC" key for it to light up and the "REC PLUS" function to start, which is immediately effective in this case
as the "learning process" has already been implemented;
2) REC PLUS:
- After the first week of continuous learning, the water heater always prepares the amount of hot water accor-
ding to a statistical prediction of demand which is supplied in time: to do so, the temperature will be automati-
cally determined which will always be between a Tminimum=40°C and a maximum temperature that is set by
the user (by default, the maximum temperature is equal to the value shown in the data sheet [Attachment A])
- Press the REC key for long for the ECO LED to flash for about 4 s and the learning process restarts (from the
first week). This is used to delete the user demand from the memory and restart (hard reset).
- Caution: when the REC key is on and the "+/-" keys (Fig.3-4) or the "REC" key itself are pressed, the Eco soft
mode described above is accessed (the REC key goes off)Al fine di assicurare un corretto funzionamento
dell'REC, si consiglia di non scollegare il prodotto dalla rete elettrica.
In order to guarantee proper REC operation, it is recommended not to disconnect the product from the mains.
EXTRA POWER FUNCTION
(for models featuring a user interface as represented in figure 3)
The product usually operates at its basic power level.
The EXTRA POWER function activates additional power to speed up the rate at which water is heated. To
activate it, press the
To deactivate it, press the same button again; the light will switch off.
SMALT POWER SYSTEM
The SMALT POWER SYSTEM, our own unique solution, is an electronic system to protect the tank against
corrosion, which helps the optimal longevity of your water heater tank even if in case of presence of extremely
aggressive water. The electronic circuit creates a potential difference between the tank and the titanium
electrode, in order to ensure optimal protection of the tank and prevent corrosion..
The proper functioning of the protection system requires a permanent supply connection to 230V, even in
cases of arrest of function of heating water.
In order to obtain a proper functioning of the appliance, the manufacturer recommends every 3 years to
carry out routine maintenance, replacing in case it's needed the magnesium anode.
The electronic circuit, in addition to being connected to the mains at 230V, is also connected to the electrode
of titanium and protection to the tank to be protected.
The function of the protective device is marked by continuous green light
presence of a sufficient voltage in the terminals of the circuit.
