3. STARTING AND OPERATION

3.1. Commissioning

3.1.1. 

Shut off the hot water supply of the central water supply system. Before connect the appliance to power source, 

fill the tank up with mains water. To do this, turn on hot water mixer tap

and then tap of cold water supplied to the water heater.

3.1.2. 

Once the water heater is full, the water will flow from the mixer tap. Check the flange for leakages. Center it and tighten

the nuts if necessary.

3.1.3. 

Turn the hot water tap on the mixer off.

3.1.4. 

Connect the appliance to power source.

3.2. Temperature control and activating the functions

Press the ON/OFF button (

A

 in Fig. 3) to switch on the appliance. Set the desire temperature by using  «+» and «-» buttons. Setting 

level is between 40°С and 80°С. Each press of the «+» and «-» button increases or decreases the set temperature by 10°С.

During the heating phase, the LEDs (

1-5

 in Fig. 3) corresponding to the temperature

reached by the water so far remain lit in a fixed manner; all subsequent LEDs (up to the set temperature) flash progressively.

If the temperature drops, for example after hot water has been used, the heating is reactivated automatically and the LEDs between 

the last fixed light and the light corresponding to the set temperature will resume flashing progressively.

In the event of a power failure or if the product is switched off using the ON/OFF button (

A 

in Fig. 3), the most recently set tempera-

ture remains memorised.

During the heating phase, a slight noise may be produced as a result of the water heating

process.

Standart mode

In the standard  mode, the water is heated at the minimum power (60% of the maximum power).

FAST mode

In the «FAST» mode, the water is heated at an average power (80% of the maximum power). To enable or disable this mode, press 

the «FAST» button (

B

 in Figure 3).

BOOST mode

In the «BOOST» mode, the water is heated at the maximum power (100% of the maximum power). To enable or disable this mode, 

press the «BOOST» button (

C

 in Fig. 3).

«ECO EVO» function

The ECO EVO function is a self-learning software that saves the hot water consumption schedule and in due course optimizes the 

water heating according to your habits.

The operation of the ECO EVO software consists of an initial training period that lasts one week, during which the device heats the 

water up to a user-specified temperature.

Starting from the second week, the software regulates the heating of the water in accordance with the real needs that were deter-

mined by the device during the first week. The maximum efficiency of the ECO EVO function is achieved after four weeks of training.

Press «+» and «-» buttons simultaneously to activate the ECO EVO function. If the water temperature is changed manually when the 

ECO EVO function is on, the ECO indicator will turn off, the recording of consumption habits will stop and the appliance will start 

operating in the selected mode, and the ECO EVO function will be inactive. 

Press «+» and «-» buttons  simultaneously to reactivate the ECO EVO function, and the appliance will continue to record the 

consumption of hot water.

Press and hold «+» and «-» buttons simultaneously for 5 seconds to delete the heating data from the memory. After the restart, ECO 

button will start flashing and the process of training will start again.

In order to ensure correct operation of the ECO EVO function, the product should not be disconnected from the mains electricity.

«Thermal disinfection cycle» function (anti-legionella)

The anti-legionella function is activated by default. It consists of a heating/maintenance cycle of the water at 60°C for 1 hour so as to 

carry out thermal disinfection action against the relevant bacteria.

The cycle starts at the first ignition of the product and after each re-ignition which follows a lack of mains power. If the product 

always work at a temperature below 55°C, the cycle is repeated after 30 days. When the product is off , the anti-legionella function is 

not active. If the appliance is switched off during the anti-legionella cycle, the product turns off and

the function is not completed. At the end of each cycle, the operating temperature returns to the value set previously by the user.

The activation of the «anti-legionella cycle» is displayed as a normal temperature setting at 60°C.

To permanently disable the anti-legionella function simultaneously press and hold down the «FAST» and «BOOST» buttons for 5 

sec.; confirming deactivation the LED 40°C will flash rapidly for 5 sec. To reactivate the anti-legionella function, repeat the operation 

described above; to confirm the reactivation of the LED 60°C will flash rapidly for 5 sec.

Anti-freeze function

The anti-freeze function is the appliances automatic protection to avoid damages caused by very low temperatures below 5°C, in 

the event in which the product is turned off during winter. 

It is recommended that the product remains plugged in to the mains power, even if it is inactive for a long time.

Once the temperature rises to a safer level such as to avoid damage from ice and frost, the water heating is switched off again.

Reset/Diagnostics

When one of the malfunctions described above occurs, the appliance will enter its «fault status» and all LEDs on the control panel 

will flash simultaneously.

Diagnostics: 

to enable the diagnostic function, press and hold the ON/OFF (

A

 in Fig. 3) and FAST (

B

 in Fig. 3) buttons for 5 seconds.

The type of fault is indicated by five LEDs (

1-5

 in fig 3) according to the following scheme:

LED 60°C 

- NTC 1/NTC 2 temperature sensors broken (open or short-circuited);

Before cleaning, isolate the appliance from the mains by 
unplugging it or turning the switch off
