1. The cooling fluid (R134a) is compressed in the high efficient compressor, raising its pressure and temperature. 2. In the condenser (not in direct contact with the water), the heat energy in the cooling fluid is transmitted to the water in the water storage heater. 3. -
Page 10: Transport
TRANSPORT The equipment must be carried in an upright position. The equipment must be raised and lowered with extreme care, to avoid impact that could damage the material. Make sure the belts and/or transportation straps do not damage the material. Always use suitable means to transport the material (pallet lift, forklift, etc.) WARNING Correct transport position... -
Page 11: Installation
INSTALLATION SAFETY AND CONTROL DEVICES 4.1.1 High/Low Pressure Switch In case of running outside the range of pressures recommended and defined by the supplier, the equipment will switch off and indicate error in the electronic panel. 4.1.2 Thermal fuse Thermal fuse is factory set by the manufacturer, and ensures that the water temperature in the hot water tank does not exceed the maximum value. -
Page 12: Pressure Reducing Valve
4.1.7 Pressure Reducing Valve * The pressure reducing valve must always be installed upstream from the safety device, and ready to activate in situations when the pressure in the circuit exceeds 3 bar (0.3MPa). This valve comes with a pressure gauge. * Parts that are not delivered by the manufacturer. -
Page 13: Air Inlet/Outlet Installation
Adjust the levelling legs of the appliance. Acceptable is the tilt angle 1° rearward. If equipment tilts other than back- wards, this will cause condensates to deposit in the tank. WARNING AIR INLET/OUTLET INSTALLATION As the AQUA HP absorbs heat during its operation, the air flow (inlet/out- let) must be directed to unheated areas. -
Page 14: Installation With Ducts
4.4.2 Installation with Ducts The Heat Pump is prepared to install ducts with diameter of 160 mm and 190 mm, in its air intake and extraction zones: Inner Ø 160 mm Outer Ø 190 mm Max Length Ducts Ø 160 Ø... - Page 15 Using Ambient Air The monobloc unit may also be placed in a heated room, but the air flow must be directed to an unheated room. Bear in mind that because of air flow, cooling the unheated room can affect the adjacent heated rooms.
- Page 16 Using Ambient and Outside Air A branched duct can be used to inflate air into the equipment. So, you can get hot air in the summer, from the outside, and hot air in the winter from an unheated room. HEATED OR UNHEATED AREA UNHEATED min 50 m...

Page 24: Eco Mode
5.5.1 mode In ECO operating mode, the equipment runs only as a Heat Pump to heat the water in the storage water heater. Thus, we could generate a greater efficiency, and savings for the user. Every time the user feels it necessary, may switch on the support electrical heater, using this mode, manually pressing the key (E-HEATER). -
Page 25: Tcc Mode
5.5.5 mode The TCC function provides the possibility of raising the water temperature when an alternative power source is available (solar photovoltaic, wind or other), increasing the efficiency of the heat pump and making the alternative power source profitable. To this end, it is sufficient to connect a cable from the inverter to the equipment's control board. The cable connection on the control board must be made at the voltage-controlled terminals. -
Page 26: Chrono Scheduling Of The Heat Pump
5.5.6 Chrono scheduling of the heat pump The heat pump has an internal clock that allows the user to set two periods of operation for the control of the equipment. These periods can be distinctly defined as weekly (Monday to Friday) or weekend (Saturday and Sunday). -
Page 27: Chrono Scheduling Of The Recirculation Pump
5.5.7 Chrono scheduling of the recirculation pump The heat pump has an internal clock that allows the user to set two periods of operation for the pump of recirculation. These periods can be distinctly defined as weekly (Monday to Friday) or weekend (Saturday and Sunday). - Page 28 Parameter P12 = 4: The heat pump controller assumes the control of a recirculation pump in parallel with the heat pump control. The pump of recirculation is driven by the hourly period set by the user and the temperature in the heat accumulator.
