Hitachi’s AquaFREE outdoor unit absorbs heat from the air outside and transfers it to the internal unit, which in turn transfers the absorbed heat to the water circuit. By utilising the Thermodynamic principles of Heat Pump technology it is possible to upgrade the energy available in the surrounding air and provide up to three times more energy than the power consumed. This range has three models from 8kW to 14kW which offer the following benefits: • High COP and EER COP of 4.1 and EER of 3.5 • Low Running Costs Large savings over traditional heating methods • DC Inverter Technology Hitachi pioneered ‘DC’ Inverter driven Air Conditioners and use this technology to drive its compressors and fans. The result is a saving of up to 30% on using Fixed Speed technology • Environmentally Friendly 30 ~ 50% reduction in CO2 emissions • Standard Controller The Hitachi programmable Wireless Controller is designed to control your heating system efficiently, providing comfortable temperatures when you are at home and energy savings when you are away • Control Features • Outside Temperature Compensated (OTC) control • Electric Heater Control • Summer Switch-Off • Outdoor Temperature Limit • System Frost Protection Ras-4/5h(v)rnme Wireless Remote Controller RWM FSN1E RAS-H(V)RNM(E)
