ECOi 3 Way is one of the most advanced VRF heat
recovery systems available. Not only oering
high-eciency and performance for simultaneous
heating and cooling, its sophisticated design makes
installation and maintenance much easier.
• Simultaneous heating and cooling for total control
• Single footprint size for all unit capacities (8-16HP)
• DC inverter technology combined with R410A for
excellent eciency
• System conguration from 8HP to 48HP
• Diversity ratio 50-130%
• Sound levels: from 54.5dB(A)
• Quiet mode oers a further 3dB(A) reduction
• Extended pipe runs of up to 150m
• COPs to 4.1
• Provides cooling down to -10°C ambient
• Connectability of 40 indoor units from 24HP upwards
Extended operating range - better output at lower
temperatures
The operating range for heating has been extended to
-20°C. The remote controller temperature setting for heating
operation has also been extended from 16°C to 30°C.
