  • Page 10 THERMODYNAMIC CYCLE The heat pump water heater does not directly heat water using electrical energy, but makes a more rational use of the latter to obtain the same result in a more efficient manner, namely by consuming approx. 2/3 less water. The efficiency of a heat pump cycle is measured by the Coefficient of Performance (COP), i.e.

  • Page 12 Compressor (*) Inhales the gas from the evaporator and compresses it in the condenser. Because of the job of compression, the vapor goes out of the compressor with more pressure and strongly overheated. Maintain the conditions of operation of the compressor within the parameters brought in chart, if not respected, not only the performances won't be optimal, but it could present malfunctions and shortening of the life of the compressor.

    Thermostatic valve (*) Mainly constituted by a body valve, a capillary pipe and a bulb. The body valve is installed on the pipeline of the gas before the evaporator, and the bulb is positioned on the outlet pipe of the evaporator. the valve of lamination has the assignment to reduce the pressure of the R134a.

    PRO-TECH Anode + Magnesium anode The exclusive PROfessional TECh system solution is an anodic anti-corrosion electronic protection system with a modulated current (24 V). It ensures maximum durability in terms of the boiler used in the water heater. The electronic circuit creates a difference in potential between the boiler and the titanium electrode, so that optimal boiler protection is guaranteed, thereby preventing its corrosion.

    FUNCTIONING MODES How to choose the mode Pressing the MODE button is possible to switch between functioning modes in this sequence: How to navigate menu Info and Installer menu The menu “info” (L) regards the information about device status, in the menu “Installer” (P/C) is possible to change time and temperature settings, functioning mode activation.
  • Page 20 AUTO mode This mode is available by default and is the starting working mode set by factory. Recommended for winter to ensure the better comfort. AUTO mode heats the water with a rational use of the heat pump and, only if necessary, of the electrical resistance, according to these two parameters: and Time_W.

  • Page 22 BOOST mode This mode is available by default. The BOOST is a temporary mode that shall be set by the user when he has an urgent need of hot water. By activating this mode, the water heater simultaneously uses the heat pump and heating element to reach the desired temperature in the shortest possible time.
  • Page 23 > Case 2: T set-point GREEN mode This mode can be selected only if enabled via installer menu (P4 Parameter ON). The GREEN mode shall be set in order to ensure energy saving; this function is recommended for air temperatures above 0°C during the hours of heating. In this working mode heating is performed with the heat pump only whatever the temperature set by the user or the available electrical power supply time.
  • Page 24 VOYAGE mode This mode can be selected only if enabled via installer menu (P6 Parameter ON). Studied for situations in which users are absent from the appliance’s operating location; this mode allows for programming the number of days of absence, during which the water heater will remain turned off.
  • Page 25 PROGRAM mode: P1/P2/P1+P2 This mode can be selected only if enabled via installer menu (P11 Parameter ON). Activating Program the device allows to reach the set delivery water temperature at the time required, giving priority to heating by heat pump and, if necessary, through the heating element. The final user can set two different programs with two different temperatures and times to be performed separately (P1 or P2) or eventually together (P1+P2).
