The system supports a single outdoor unit up to 12hp, with the option to combine up to three units for a total capacity of 36hp. This multi-outdoor configuration connects to up to 52 indoor units.
The new series incorporates compliant safety measures for R32 refrigerant, including new leak detectors and alarms in line with EN 378 and IEC 60335240 standards.
