The Vaillant climaVAIR pro VAI5-065WN is a robust 6.5kW (22,000 BTU) split system delivering comprehensive environmental control for large residential zones, retail suites, and conference facilities. Delivering an A++ energy efficiency rating in cooling mode and A+ in heating, it combines heavy-duty performance with minimal operational expenditure. The system includes an intelligent absence function that holds ambient indoor temperature safely at 8°C in winter and 27°C in summer to prevent structural dampness and thermal extremes when unoccupied. An illuminated digital display gives immediate feedback on operational parameters, whilst low-noise cross-flow fan assemblies maintain refined indoor comfort. Wi-Fi integration allows full remote parameter management through iOS and Android applications. F-Gas certified installation is mandatory to activate the 5-year manufacturer parts warranty.
