3. STARTING AND OPERATION
3.1. Commissioning
Before connect the appliance to electricity source, ll the tank up with mains water. To do this, turn on the domestic mains
tap and the hot water tap.
Once the water heater is full, the water will ow from the domestic mains tap. Visually check for water leaks from the ange
and slightly tighten it, if necessary.
Power the appliance at the switch.
3.2. Temperature control and activating the appliance function
• For models featuring a user interface as represented in figures 6 and 7:
Press the
knob (Ref. ) to switch on the appliance. Set the desired temperature by using the "+" and "-" knobs. Setting
level is between 40°C and 80°C. During the heating phase, the LEDs (Ref. 1-5) corresponding to the temperature reached by
the water so far remain lit in a xed manner; all subsequent LEDs (up to the set temperature) ash progressively.
If the temperature of the water heater drops (for example after hot water has been used) the heating is reactivated
automatically and the LEDs between the last xed light and the light corresponding to the set temperature will resume
ashing progressively.
The first time the appliance is switched on, it will be set to a temperature of 70°C.
In the event of a power failure or if the product is switched o using the
memorized. During the heating phase, a slight noise may be produced as a result of the water heating process.
• For models featuring a user interface as represented in figures 8 and 9:
Press the
knob (Ref. А) to switch on the water heater. The appliance has 4 heating modes:
Manual, 1 (Programming 1), 2 (Programming 2), and P1+P2 (Programming 1 and 2) combined.
Every time the "Mode" knob is pressed, a di erent operating mode will be selected; the mode is indicated by the ashing of
the corresponding LED on the display. Functions are selected on a cyclic basis, in the following order: P1 (Programming 1)
P2 (Programming 2)
Programs P1 and P2 are set by default to the 07:00 and 19:00 time bands, and to a temperature of 70°C.
The "Manual" function (the "Manual" LED lights) allows the user to set the desired temperature simply by turning the "Set"
knob until the desired temperature is displayed (the adjustment interval is 40°C – 80°C). If the knob is pressed, the setting will
be stored in the appliance memory and the product will begin operating in "Manual" mode with these settings.
: If the "Manual" function is used in conjunction with the "ECO" function (see "ECO function" paragraph), the temperature
will be set automatically by the water heater; this means the "Set" knob will be disabled. If it is moved, "ECO" will appear on
the display for 3 seconds. If you wish to adjust the temperature, you will have to disable the "ECO" function.
The functions "Programming 1" ("P1" LED lights), "Programming 2" ("P2" LED lights) and "Programming 1 and 2"
("P1+P2" LEDs lights) can be used to program water heating to desirable time (one or two time bands in the day).
Press the "Mode" button until the LEDs relating to the desired program begin ashing to choose this function. After that, 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 "Set" to store the time band setting in the appliance memory.
Next, set the water temperature to the desired level (from 40°C to 80°C). Press "Set" knob to begin water heater operation in
"P1" or "P2" mode.
If you have selected "P1+P2", you will need to repeat the time band and temperature setting procedures for the second time
period. Interval for which there is no set heating time will not be activated. The individual "P1" or "P2" programs are of equal
importance and may be con gured independently for greater exibility.
When one of the programming functions ("P1", "P2" or "P1+P2") is operated, the "Set" knob is disabled. If it is moved, "Pr" will
appear on the display for 3 seconds. If you wish to adjust the parameters, press the "Set" knob.
PLUS: If one of the programming functions ("P1" or "P2" or "P1+P2") is used in conjunction with the "ECO" function (see
"ECO function" paragraph), the temperature is set automatically by the water heater. It is therefore only possible to set the
desired time band for hot water availability. If the "Set" knob is moved, "PLUS" will appear on the display for 3 seconds.
Warning: in any setting procedure, if the user does not perform any actions for 5 seconds, the last setting will be stored in the
appliance memory.
EXTRA POWER/DOUBLE POWER function
• For models featuring a user interface as represented in figures 7 and 9:
The water heater usually operates at its basic power level. The EXTRA POWER/DOUBLE POWER function activates additional
heating element to speed up the rate of water heating. To activate it, press the
same knob again.
function
ECO function starts special automatic cycle of cleaning the water and the inner surface of the water heater from bacteria
during which the optimum temperature and the rate of water heating is selected, at which most harmful bacteria that may
be present in warm dead water are killed.
This function should be applied if the water heater was not used more than 3 days or if you do not heat water above 70°C.
The optimum operating time of this function: 6-12 hours. For power saving, use of ECO function for more than 24 hours at
one-time switching on is not reasonable.
