The TERREL PLUS SERIES units are the successor to the popular TERREL series, featuring improvements such as higher efficiency (SEER 8.5 and SCOP 4.6) and an A+++ / A++ energy rating. Another bonus is the lower noise level of the indoor units, where models with 2.7 and 3.5 kW capacities start at a very quiet 18 dB(A). In addition to standard features (Wi-Fi connectivity, multi-directional louver movement, plasma generator, operation lock contact, wall-mounted controller connectivity, and more), the standard equipment also includes a night mode with quiet operation of the outdoor unit. The entire series returns to white indoor units with a decorative glossy silver trim.
