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 talk about "split" we mean that the refrigeration circuit is divided between the two units, the external one and the internal one. The outdoor unit contains the heart of the refrigeration 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 internal 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 vessel, to safely allow for quick and practical installation. The OMNIA ST 3.2 differ from the OMNIA S 3.2 in that they have integrated a storage tank for domestic hot water directly in the internal unit. This accumulation is 190L for sizes from 4 to 10, while it is 240L for the larger sizes, from 12 to 16T. But not only that, OMNIA ST 3.2 can be customized according to your needs, with an 18L inertial kit, a kit for solar integration on the storage or with a kit for the management of 2 different zones, classic direct and mixed, in case where we needed 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 externally and produces hot water up to 65°C in nominal conditions. Ferroli's new Full Inverter concept uses DC inverter modulations on the 3 main energy-intensive components of the machine, i.e. compressor, fan and pump. This allows the power supplied to be modulated 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 reduction of inrush currents, avoiding surges in the network 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 needs, but can easily be integrated with a Ferroli boiler .

The internal unit, the heart of the hydraulic distribution

If the external unit contains the heart of the refrigeration circuit, the Internal Unit contains the heart of the hydraulic 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 user needs. Stainless steel plate exchanger, pressure gauge and pressure 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 in an easy and extremely simple way

Modbus protocol Can be interfaced with BMS/BACS automation and management systems

Heating and cooling Full Inverter modulation finely follows the desired set points, with the possibility of setting hot and cold climate curves, further optimizing consumption for the user

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

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

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

Fast DHW Priority to DHW production to bring the boiler to the set setpoint in the shortest possible time

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

Silent mode Reduces the compressor frequency and the fan speed, 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 the outside, for example from the zone thermostat

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

Antifreeze protection Hot operation of the heat pump with circulator ON and possible electric booster

The brand new Connect CRP and Connect CRP Zone

The interface on the machine 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 is possible to insert it into a classic 502 box, or leave it stand-alone on its practical table feet
