2. GENERAL FEATURES

2.1 Presentation of the system

> GENERAL CHARACTERISTICS:
This series of air-water heat pumps satisfies the winter and summer air conditioning needs of residential and commercial systems of small and medium power and allows the pro-
duction of domestic hot water (DHW) through an external boiler.
All the units are suitable for split installation (which avoids the risk of freezing in particularly rigid outdoor applications) and are capable of producing water up to 65 ° C and can
therefore be used in radiant systems, fan coil units, radiators.
The user interface consists of a digital controller mounted on the indoor unit, equipped with a large display and simple setting commands.
> INDOOR UNIT FEATURES
• All the components (plate heat exchanger, circulator, etc.) and all the pipes of the hydraulic circuit are thermally insulated to avoid the formation of condensation and reduce
heat losses.
• Brazed stainless steel water / gas plate heat exchanger controlled and protected by temperature probes on both the water and refrigerant side
• Low consumption circulator with brushless DC motor
• System electric heater (3 kW single stage for mod. 4 - 6 - 8 - 10 - 12 - 14 - 16, 6 kW single stage for mod. 12T - 14T - 16T)
• Water flow switch
• Plant expansion vessel of 10 liters
• 3-way diverter valve for DHW production
• Automatic air vent
• Water pressure gauge
• 3 bar safety valve
• Water filter (Y-shape) supplied (not installed)
> OUTDOOR UNIT FEATURES
• Refrigerant circuit contained in a compartment sheltered from the air flow to facilitate maintenance operations
• Reduced inrush current thanks to Inverter technology
• Compressor with twin rotary DC INVERTER motor equipped with crankcase oil heater, positioned on anti-vibration rubber supports and wrapped in a double layer of sound-
absorbing material to minimize vibrations and noise
• DC inverter compressor that allows to modulate the capacity from 30 to 120% of the rated capacity
• Electronic biflow expansion valve
• Reverse cycle valve
• Axial fans with brushless DC motor complete with safety protection grilles
• Finned coil consisting of copper pipes and hydrophilic aluminium fins with anti-corrosion treatment
• The circuit is controlled by temperature probes and pressure transducers and protected by high and low pressure switches.
• All the units are equipped with variable speed control of the fans which allows operation with low external temperatures in cooling and high external temperatures in heating.
• External air temperature probe already installed on the unit.
> OUTDOOR UNIT ACCESSORIES
• AVG - Rubber antivibration dampers.
> SYSTEM ACCESSORIES
TP - Temperature probe: this is a probe that can be used to expand the control functions of the unit.
In fact, it can be used for:
• management of a 2-zone kit (direct and mixed) external to the unit for reading the mixed zone flow
• solar thermal management for reading the temperature of the solar collector
