Efficiency marries comfort for integrated storage

OMNIA ST 3.2 is the evolution of OMNIA S 3.2 and is part of the new range of Full Inverter R32 split heat pumps by Ferroli. When we speak of "split" we mean that the refrigerant circuit is divided between the two units, the external and the internal one. The outdoor unit contains the heart of the refrigerant circuit, from the compressor to the fan with the air side exchanger, which is connected to the refrigerant gas pipes towards the indoor unit.

The indoor unit, on the other hand, contains the heart of the generator's hydraulic circuit with all the main pre-installed components, such as the high-efficiency circulator and the expansion tank, to safely allow quick and practical installation. The OMNIA ST 3.2 differ from the OMNIA S 3.2 in having integrated a storage tank for domestic hot water directly into the internal unit. This accumulation is 190L for sizes from 4 to 10, while it is 240L for uppers, from 12 to 16T. But that's not all, OMNIA ST 3.2 can be customized according to your needs, with an 18L inertial kit, kit for solar integration on the storage tank or with a kit for managing 2 different zones, classic direct and mixed, in case where we need 2 different temperatures on the terminals in the house

Thanks to its wide operating range , among the widest on the market, OMNIA ST 3.2 works down to -25°C outside and produces hot water up to 65°C in nominal conditions. The new Full Inverter concept by Ferroli uses DC inverter modulations on the 3 main energy-intensive components of the machine, i.e. compressor, fan and pump. This makes it possible to modulate the power supplied by finely tracking the thermal load and allowing the user very high efficiencies and important energy savings . Furthermore, Ferroli's Full Inverter concept allows for the inrush currents to be reduced, avoiding sudden changes to the grid and guaranteeing a longer useful life for the components. With sound levels among the lowest on the market , OMNIA ST 3.2 is able to satisfy all system requirements, but can easily be integrated with a Ferroli boiler.

The indoor unit, the heart of hydraulic distribution

If the outdoor unit contains the heart of the refrigerant circuit, the indoor unit contains the heart of the water circuit. OMNIA ST 3.2 is much more than an exchanger with a pump. The hydronic module includes all the main components of the system and can be customized according to the user's needs. Stainless steel plate heat exchanger, pressure gauge and sensors, expansion vessel, safety valve, automatic vent and brushless DC circulator are just some of the components you will find inside

The control system

The user interface has been equipped with capsense technology with 2.8” graphic display, which allows the user to interact with the product easily and extremely simply

Modbus protocol It can be interfaced to BMS/BACS automation and management systems

Heating and cooling Full Inverter modulation finely follows the desired setpoints, with the possibility of setting heating and cooling climatic curves, further optimizing consumption for the user

Domestic hot water production When the DHW temperature probe calls the machine, it automatically switches to the domestic hot water tank with dedicated DHW set point. 3-way diverter valve supplied as standard

Smart Grid input from photovoltaic and grid Digital Smart Grid inputs for the management of an input from the photovoltaic system and from the electricity grid. These allow you to optimize consumption and bill costs

DHW tank electrical resistance The DHW electrical integration serves as integration, anti-legionella or reserve source in the event of an anomaly

Fast DHW Priority to DHW production to bring the storage tank to the set point in the shortest possible time

Anti-legionella function Allows you to set anti-legionella weekly cycles

Silent mode Reduces the frequency of the compressor and the speed of the fan, so as to significantly reduce noise. Programmable on time slots

ON/OFF From external contact. Activation and deactivation via an external contact, for example from a zone thermostat

Hot / cold From external contacts. Summer/winter switching signal from outside, for example from the zone thermostat

ECO function Dedicated setpoint for " Eco " operation. Settable with daily time band

Anti-freeze protection Heat pump operation with circulator ON and possible electric booster

The brand new Connect CRP and Connect CRP Zone

The on-board interface communicates easily with the new Connect CRP intelligent systems, which can manage up to 8 thermostats divided into 2 zones, one direct and one mixed .

Connect CRP is the brand new remote controller accessible via APP , available for both iOS and Android .

The Connect CRP Zone, on the other hand, is a zone thermostat that communicates via RF with the Connect CRP. It can be placed in a classic 502 box, or left stand-alone on its practical table feet
