i-FX-Q2-Y 0502 - 1102
Full inverter multi-purpose outdoor unit for use in 4-pipe systems for the simultaneous production of hot and chilled water in two independent hydronic circuits. These units are able to simultaneously satisfy the demand for hot and cold water through a system that does not require seasonal switching and is therefore a valid alternative to traditional plants with chiller and boiler. Each circuit works with a variable speed drive semi-hermetic screw compressor using R134a, two shell and tubes heat exchangers and a source side coil heat exchanger shared by both circuits. The cold side shell and tube heat exchanger acts as an evaporator for the production of cold water, while the hot side shell and tube heat exchanger works as a condenser for the production of hot water. The source side auxiliary finned coil works as either condenser or evaporator as required by the loads.

Features
UNIQUE PROPOSAL
Unit designed to satisfy the hot and cold side requirements simultaneously, for 4-pipe systems without any particular operation mode setting.
ENERGY SAVINGS
Energy savings guaranteed by advanced operation logic. The best operation mode is set completely automatically and independently by the unit’s controller, in order to minimize the absorbed energy whatever the heating and/or cooling demand might be.
HIGH EFFICIENCY
High full load and partial load efficiency in both heating and cooling, using inverter technology to continuously modulate compressors operation and EC fans as standard, in order to deliver the exact amount of energy based on the actual needs of the plant. High efficiency means reduced energy consumption throughout the entire year, for any operation mode and any outdoor condition.
ErP READY
The highest level of efficiency at part load, thanks to the inverter technology, can meet and exceed the minimum Seasonal Coefficent Of Performance, SCOP, (only for reversible units) and the Seasonal Energy Performance Ratio, SEPR, in accordance with the eco-sustainable design requirements for all products using energy.
WIDE OPERATING RANGE
Unit´s operation guaranteed with external air temperature down to -12°C during winter and up to 46°C during summer. Production of hot water up to 60°C without accessories and chilled water from -8°C to +18°C in order to suit any possible application.
UNIT AND PLANT HARMONY
Low inrush current and a higher power factor than similar fixed speed units, provide an easy electrical installation which is not stressed during start-up nor are extra devices for power factor correction needed. The use of VSD technology allows the unit to partialize in a stepless way, with consequent lower leaving water temperature fluctuations.
TRUE SILENCE
At partial loads (ie for most of the year), thanks to the use of EC fans and VSD screw compressors, i-FX-Q2-Y units are characterized by lower noise emissions compared to fixed speed units.
FLEXIBLE SELECTION
i-FX-Q2-Y units can be selected beyond the nominal point, giving the possibility to contain the initial investment (boost selection) or to enphasize even more the efficiencies (derating selection).

Electronic control W3000+
W3000+ features an easy-to-use interface and a complete LCD display that allows one to consult and intervene by means of a multi-language menu (19 languages are available). The diagnostics includes a complete alarm management, with the “black-box” and the alarm history display for enhanced analysis of the unit operation. The programmable timer manages a weekly schedule organized into time bands to optimize unit performance by minimizing power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points. As option, KIPlink is available - Keyboard In Your Pocket. KIPlink is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the smartphone or tablet.
The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimize performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available.
Optional proprietary devices can perform the adjustment of resources in systems made of several units. 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, Bacnet MS/TP RS485, Konnex, ModBus TCP/IP, SNMP. Compatibility with the remote keyboard (up to 8 units).
