FOCS-N-G05-Y 2022 - 2622
Outdoor heat pump unit for the production of chilled/hot water with semi-hermetic screw compressors optimized for R513A, axial-flow fans, external coil with copper tubes and aluminium fines, shell and tubes heat exchanger designed by Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A. and electronic expansion valve.
Base and supporting structure and panels are made of galvanized epoxy powder coated steel with increased thickness.
These units are designed for two-pipes systems and are able to produce hot or cold water according to the selected operation mode; the precise thermoregulation guarantees an optimal response to load variations, in every operating condition.

Features
HIGH EFFICIENCY
Unit in Class A as per Eurovent (in heating). High efficiency for low energy consumption during the operating hours.
LOW GWP REFRIGERANT
New generation refrigerant R513A, with reduced greenhouse effect in comparison with traditional HFC refrigerants (Global Warming Potential GWP of R513A = 572, GWP of R134a = 1300 as per IPCC rev. 5) and zero impact on the ozone layer. Non-flammable (ASHRAE 34, ISO 817: class A1).
SMART DEFROST
The advanced self-adaptive proprietary defrosting logics take into account all the operating parameters and the external conditions: the number and duration of the defrost cycles are therefore reduced to the minimum necessary ensuring an increase in efficiency and net heating capacity of the units.
COMPACTNESS
Reduced dimensions, for easy installation even in sites with space´ constraints
WIDE OPERATING RANGE
Unit´s operation guaranteed with external air temperature down to -10 °C during winter and up to 50 °C during summer.
HOT WATER SUPPLY
Supply of hot water in use up to 60°C, offering maximum versatility with respect to different plant engineering solutions.

Electronic control W3000 TE
The W3000TE controller offers advanced functions and algorithms. The large format keyboard provides a complete overview of the unit's status. The controls and the complete LCD display favor an easy and safe access to the unit's setup. These resources provide assessment and intervention of the unit, by means of a multi-level menu, with multiple languages available. The LED icons immediately show the circuit's operating status, as well as the fans and the water pumps (if present). The touch screen interface: 7.0” WVGA color display with adjustable LED back-light and front USB port is available as an option. The touch screen technology allows intuitive navigation between the various screens, safe access to the data with a three-level password protection as well as the graphic display of the performance of some monitored measurements.
The diagnostics are comprised of a complete alarm management system, with “black box” (via PC) and alarm log functions (via display or also PC) for a better analysis of the unit's performance.
For the systems made up of several units, the adjustment of the resources is performed by optional proprietary devices.
Consumption metering and performance measurement are possible as well. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet-over-IP, Echelon LonWorks, Bacnet MS/TP protocols.
Compatibility with the remote keyboard to manage up to 8 units.
The presence of the programmable timer allows for the creation of an operating profile containing up to 4 typical days and 10 time bands.
The control is characterized by the continuous modulation of the unit capacity, based on PID algorithms and referring to the water delivery temperature.
Optionally (VPF package), capacity modulation can be integrated with hydraulic flow modulation, thanks to inverter-driven pumps and to specific resources for the hydraulic circuit.
