and time bands
Default settings
When one of the programming functions ("P1" or "P2" or "P1 and P2") is enabled, the "SET" knob is
disabled. If it is moved, "Pr" appears on the display for 3 seconds. If you wish to adjust the parameters, you
have to press the "SET" knob.
During the periods for which the use of water has not been scheduled, water heating is disabled. The
individual "P1" or "P2" programmes are of equal importance and may be configured independently by the
user for greater flexibility.
If the product is disconnected by the power mains for a long period, all the settings are stored into the
appliance memory except for the local time which has to be set again (when the product is switched on, the
appliance works in MANUAL mode until the local time is set again, resuming all the stored settings).
3.3 ECO
The ECO function is a software program which automatically "learns" the consumption levels of the user,
helping to minimise heat dispersion while maximising the amount of energy saved.
The operation of the ECO software consists in an initial memorising period which lasts one week, during
which the product begins operating at the temperature set by the user and adjusts it every day to energy
requirements in order to maximise the amount of energy saved. At the end of this "learning" week, the
ECO software begins activating the water heating process in accordance with the time periods and
quantities selected automatically by the product after it has finished to "learn" the user tapping profile. The
product ensures a store of hot water even during the periods when hot water production has not been
scheduled.
To activate the ECO function press the corresponding "ECO" button, which lights up; to deactivate the ECO
function press the illuminated "ECO" button, which is switched off.
While the ECO function is active, manual temperature selection is disabled (the "SET" knob is disabled)
because the temperature is set automatically by the product. If you wish to increase or decrease the
temperature, the ECO function must be deactivated.
Whenever the ECO function or the product itself is switched off and then on again, the function starts up
from the beginning of the "learning" period. In order to ensure the ECO function operates correctly, we
recommend the product is not disconnected from the electricity supply.
The first time the product is switched on, it automatically prompts you to set the
correct time; on subsequent occasions you need to press and hold the "SET"
knob for 3 seconds.
Adjust the current hour setting by turning the "SET" knob, then confirm the value
by pressing the knob. Repeat the procedure to set the minute value.
Press the "MODE" button until the symbols relating to the desired programme
begin flashing.
At this point turn the "SET" knob to select the time band in which you would like
hot water to be available (time bands are selected in 30-minute notches). Press
the knob to store the time band setting in the appliance memory.
Next set the water temperature to the desired level by turning the "SET" knob
and clicking to memorize the setting; the appliance starts to work in "P1" or "P2"
mode.
If you have selected "P1 and P2", you need to repeat the time band and
temperature setting procedures for the second programme.
The programmes "P1" and "P2" are set by default to the 07:00 and 19:00 time
bands and to a temperature of 70 °C.
