VAI6-WN-U_EN - 10/13 - VaillantEN- 5 -INTRODUCTION5.2 Features and BenefitsTechnical Specifications PictorialSymbol DescriptionHeat pump The refrigeration system can be reversed. It allows either cooling or heating tothe room as desired.Refrigerant R-410A Refrigerant which is free of chlorine, ecological and non ozone depleting withefficiencies greater than R 407 C or than R22, providing far better COP levels.Inverter DC technology Energy saving greater than conventional inverter systems.Inverter technologyConsumption is adapted to the acclimatisation requirement in a regulated way,guaranteeing very low energy costs. The equipment can be operated underextreme temperature conditions (See page 3).Anti-dust filter General filter which eliminates much of the dirt and dust circulating throughthe unitRemote controller Remote controller: an infra-red device which allows remote access and controlto the units functionsHot start function The indoor unit fan is only operated after the indoor coil reaches temperature.Thereby eliminating cold drafts during the heating cycleAuto restart function After a power outage the unit will re-start automatically at the same setting aslast set.Valve protection A cover used to protect the service valves from the effects of bad weatherAnti-freeze All heat pump units will tend to freeze up during the colder winter months, theanti-freeze function automatically defrosts the outdoor coil as requiredAnti-corrosion casing Outdoor unit made of galvanised steel and anti-corrosion materials.Resistant even in highly saline environments.Table 5.1 Features and benefits.
