B. Extended compressor life by uniform compressor operation time

C. Automatic backup operation in the case of compressor failure or outdoor unit malfuction

Other Features

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 +46°C DB* Depending on the type of remote controller

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.

* 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

(Except for single unit installation)

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.

The other compressor can keep running

Even if a compressor in a single system fails

The other outdoor unit can keep running

Even if a whole outdoor unit fails

Even if fan motor or sensor fail
