SPLIT SYSTEM REVERSIBLE HEAT PUMP WITH DC INVERTER COMPRESSOR

New range of Full Inverter split system heat pumps with R32 eco-friendly refrigerant.

The range consists of an Outdoor Unit housing the most important elements of the refrigeration circuit, from the compressor to the air-side heat exchanger, which will be connected with the refrigerant pipes to the Indoor Unit.

The Indoor Unit on the other hand houses the main components of the heat source’s water circuit, with the pre-installation of all essential parts such as the high-performance circulator and expansion tank, to allow safe, fast and practical installation.

It is supplied standard with an electrical integration of 3kW for single phase models, and 6kW for three-phase models. Installing a split system also offers the undeniable advantage of avoiding the problem of freezing, even at the lowest temperatures (up to -25°C) and in the absence of electricity (the only real problem with anti-freeze heating elements in outdoor packaged machines).

All units satisfy the most extreme winter/summer heating/cooling needs with the capacity to produce hot water up to 65°C, making them ideal for practically all heating systems, whether radiant, with fan coil units or radiators, including the production of domestic hot water (DHW) through an external water cylinder.

Ferroli’s new Full Inverter design uses DC inverter modulation on the machine’s 3 main power-consuming components, i.e., the compressor, fan, and pump. This allows modulation of the distributed power by finely tracking the heat load, thus allowing very high energy efficiency and important power savings for the end user.

Moreover, Ferroli’s Full Inverter design reduces the inrush current, avoiding power grid fluctuations and thus improving the mission time of components. The noise levels are among the lowest in the market, and it can be used either as a stand-alone or integrated with other heat sources, for example a boiler.

All units are supplied with a temperature probe for a DHW cylinder (not supplied, to be assembled by the installer) and an outdoor air temperature probe (pre-assembled on the Outdoor Unit) for temperature regulation in both heating and cooling.

Technical Data

THE CONTROL SYSTEM

The user interface comes with Capsense technology with a 2.8” graphic display, ensuring easy and extremely simple user interaction with the product. The on-board machine interface easily communicates with the new smart Connect CRP systems, which can manage up to 8 thermostats (7 Connect CRP Zones + 1 Connect CRP with all programmable thermostat functions) divided into 2 zones, one direct and one mixed. The main control functions include:

MODBUS PROTOCOL for smart control via an external BMS.

HEATING AND COOLING with the heat pump as the only heat source. Full Inverter modulation means the setpoints can be maintained in both heating and cooling, thus optimising consumption for the user. The temperature curve setting (standard) can improve comfort and further reduce consumption.

DOMESTIC HOT WATER PRODUCTION (DHW). When the DHW Temperature probe (to be installed on the external cylinder, not supplied with the machine) falls below a certain value, the machine enters DHW mode, that is, Heating with dedicated Setpoint. 3-way diverter valve supplied standard.

SMART GRID INPUT FROM PHOTOVOLTAIC SYSTEM AND GRID. The unit is equipped with 2 digital contacts to manage an input from a photovoltaic system and the grid. These are the famous Smart Grid contacts used to optimise consumption and save on bills. The first contact (EVU) tells the heat pump when the photovoltaic system is producing: the heat pump increases the DHW setpoint with the aim of improving self-consumption (where the user has the best earnings). The contact toward the grid (SG) warns the heat pump when the electrical power costs more (if allowed by the operator), which will then be limited in accordance with customised settings. We invite you to read the manuals for more details.

REMOTE CONTROL VIA APP. Available for iOS and Android using the Connect CRP (optional) DHW CYLINDER HEATING ELEMENT. In DHW mode, the unit manages a heating element inserted in the cylinder as an integration, anti-legionella function, or reserve source in case of a failure.

FAST DHW. A function making it possible to give priority to DHW production by activating all available power sources, to bring the DHW cylinder to the setpoint in the shortest possible time.

ANTI-LEGIONELLA FUNCTION. Allows the setting of weekly anti-legionella cycles. In order for it work effectively, a heating element must be installed on the DHW cylinder or integrated boiler.

SILENT MODE. When activated, reduces the maximum compressor frequency and fan speed so as to significantly reduce noise levels. Available with 2 different levels and programmable in daily time slots (for example at night).

ON/OFF from external contact. The unit can be activated and deactivated via an external contact (for example a zone thermostat): in this case the operating mode will follow the controller settings.

WARM/COOL from external contacts. The unit can receive an external summer/winter switching signal (for example from a zone thermostat).

ECO. Dedicated setpoint for “Eco” mode. Settable with a daily time slot.

WEEKLY HOURLY PROGRAMMING. The Connect CRP (optional) allows differentiated hourly programming for each day of the week, defining the mode (COOL/WARM/DHW) and operating setpoints for each time slot.

ANTI-FREEZE PROTECTION. Heat pump operation in heating mode with the circulator set to ON and eventually an electric booster.
