Other Features A. Operating Range - Cooling & Heat pump mode Heating operation range: Extended heating operation range enables heating even when the outdoor temperature is as low as -25 C. Using a wired remote control, indoor heating temperature range can be set from 16 C to 30 C*. Cooling operation range: -10 C DB to +52 C DB * Depending on the type of remote controller Outside air temperature ( C WB) -25-20 -15-10 -5 0 5 10 15 18 Outside air temperature ( C DB) -10-5 0 5 10 15 20 25 30 35 40 52 B. Extended compressor life by uniform compressor operation time The total run-time of compressors are monitored by a built-in microcomputer, which ensures that operation times of all compressors within the same refrigerant circuit are balanced. Compressors with histories showing shorter run times are selected first, ensuring equal wear and tear across all units and extended the working life of the system. System example A,C : DC inverter compressor B,D : Constant speed compressor Load Load increase increase increase A B C D A B C D A B C D A B C D Load * Depending on accumulated operation time of each compressor * Compressor priority has possibility to be changed (e.g) Case1: AACABAD, Case2: CAAADAB, Case3: AACADAB, Case 4: CAAABAD * Also other cases available C. Automatic backup operation in the case of compressor failure or outdoor unit malfuction (Except for single unit installation) Even if fan motor or sensor fail Even if a whole outdoor unit fails Even if a compressor in a single system fails Backup operation allows uninterrupted cooling or heating to continue whist waiting for service. Users should contact their authorized service centre as soon as fault occurs.
