PAGE 22
Features and benefits 2.1 New IVX Series Hitachi is pleased to introduce a new product line of IVX Outdoor Units: IVX Premium IVX Standard 1 Improved the connected capacity ratio of Indoor Units from 50 % to 120% of Outdoor Unit capacity (depending on the models). 2 Increased the number of connectable Indoor Units up to 8 units (depending on the models). 3 Compact sizes (3, 8 and10 HP).
PAGE 23
Features and benefits Improvement of Energy-Saving through the new Indoor Unit and Remote Controller New RCI-(1.0-6.0)FSN3 - 4-way cassette and two optional air panels offer the following benefits: Benefits Outline Improvement of Energy Saving (1) The high performance heat exchanger, the highly efficient turbo fan and the new DC drain pump are adopted. (2) Energy saving is improved by the air panel with motion sensor.
PAGE 24
Features and benefits Comfortability and Installability The individual operating function is adopted. In addition, the number of connectable indoor units is increased. Reduction of Local Temperature Irregularity and Creation of Comfortable Room Conditions The individual thermo-ON/OFF control is available by one remote control switch to control multiple indoor units.
PAGE 25
Features and benefits Improvement of Comfortability Part of the discharge gas is bypassed to the heat exchanger, making use of the surplus capacity of the outdoor unit when decreasing the thermal load of indoor units. As a result, temperature increase of the heat exchanger prevents appearance of frost. The comfortable air conditioning is continuously available by decreasing the defrosting operation frequency.
PAGE 26
Features and benefits Compact and lightweight design • The new 3 HP IVX Standard is designed in a more compact and lightweight fashion in comparison with the current 3 HP IVX model. New IVX Standard 3 HP model Current IVX 3 HP model 67 kg 44 kg 800 600 300 370 950 792 • More compact and lightweight design for the new 8 and 10 HP.
PAGE 27
Features and benefits Compatibility with the piping of current installations where R22 or R407C are used. The new IVX Premium and IVX Standard are compatible with those installations that have been operating with R22 or R407C. This allows installing the IVX Premium/Standard Outdoor Units, which operate with R410A, without having to change piping installation, even when the thickness is less than the R410A piping specifications. This option is easily configured through the DSW2, by setting pin 4 ON.
PAGE 28
Features and benefits 2.2 Eco-Desing and Seasonal Efficiency To respond to the European Environmental Objectives of the 3 x 20 (-20% energy consumption, -20% CO2 emission, +20% renewable energy) within 2020, Europe revised the original Ecodesign Directive (Directive 2005/32/CE) and enlarged the applications covered. Initially the scope of Eco-Design was products using energy (E.u.P.).
PAGE 29
Features and benefits • Conditions of temperature (number of hours per outdoor temperature) for an identified climate (average climate for ErP compliance) • Building heat load (called Pdesign) HITACHI, in compliance with the Eco Design Directive, has developed the new outdoor units: UTOPIA IVX Premium and IVX Standard series, whose high efficiency level (including SEER and SCOP values) is properly informed to our customers to allow for an easy selection.

PAGE 33
Features and benefits 2.4 Installation benefits 2.4.1 Easy and flexible electrical installation Adopting transmission system H-LINK II The units interconnect via a bus called H-LINK II, consisting of 2 non-polarity cables and accepting lengths of up to 1,000 m. Accessories are available if required to increase this length to 5,000 m. Up to 160 indoor units connected to each circuit 2 Each H-LINK II bus can communicate up to 160 indoor units.
PAGE 34
Features and benefits • The H-LINK II system provides maximum flexibility for system design; installation is easy, and total costs are reduced. Furthermore, it can be controlled centrally by connecting CS-NET WEB to H-LINK II wiring. • You can also control the installation by Internet via CS-NET WEB. 2.4.
PAGE 35
Features and benefits 2.5 Start-up benefits 2.5.1 Automatic start-up test The installation is started up automatically, therefore considerably reducing the time required for the process. 2 There are the following types of start-up: • Test run and identification of the units forming the system. • Test run from the remote control. • Test run from the outdoor unit.
PAGE 36
Features and benefits Assisted-management air conditioning system The air conditioning system can be managed conveniently using the assisted management software HITACHI Service Tools. This software enables, for example, a laptop computer to be connected to the air conditioning system by means of an interface connected to the H-LINK II bus. Using different menus, the software allows you to manage all the systems connected effectively and obtain data to optimise system performance.
PAGE 37
Features and benefits 2.6 Maintenance benefits 2.6.1 Minimum maintenance The units have been designed in line with Hitachi’s philosophy, guaranteeing great reliability and robustness and reducing maintenance to a minimum. 2.6.2 Easy accessibility The system components are easily accessible. You can access all of the unit’s components to perform any necessary operations through a simple cover. The entire system is designed for maintenance operations to be easy and simple. 2 2.6.
