7. INSTRUCTIONS FOR USE
7.1 Control panel description
Refer to Fig. 14.
A Knob
Buttons ON/OFF - MODE
The control panel, constructed in a simple and rational way, comprises two buttons and a central knob.
In the upper section, a DISPLAY shows the set temperature or the detected temperature, besides other specific
indications such as the operation mode signal, fault codes, settings and information of the product’s condition.
7.2 Turning the water heater on/off
Turning the appliance on: simply press the ON/OFF button to turn the water
heater on.
Now you can set the current time (see section 7.5)
The DISPLAY visualises the “set” temperature and operation mode, while the
HP symbol and/or heating element symbol indicate the operation of the heat
pump and/or heating element respectively.
Turning the appliance off: simply press the ON/OFF button to turn the water heater off, only “OFF” appears on the
display. The protection against corrosion is still ensured, while the product will automatically ensure that the temperature
of the water in the tank does not fall below 5°C.
7.3 Setting the temperature
The desired temperature for the hot water can be set by turning the knob clockwise or anti-clockwise (the visualised
temperature will flash temporarily).
To visualise the current temperature of the water in the tank, press and release the knob; the relative value will appear for
8 seconds then the set temperature will reappear once again.
The temperatures that can be obtained in the heat pump mode vary between 50°C and 55°C, by factory default
setting, and 40°C-55°C, by varying the setting on the installer menu.
The maximum temperature that can be obtained with the heating element is 65°C, by factory default setting, and
75°C, by varying the setting on the installer menu.
