Test Operation

General Information

4.8

Sequential Start

Separates path timing of commercial power supply compressors by 3 seconds each in order to prevent

overcurrent when more than 1 compressor are to be started at the same time.

Improved wiring system enables sequential start of up to 10 outdoor units.

If you want to carry out sequential start, connect outdoor unit - outdoor unit transmission wiring as shown
below.
The outdoor unit PC board (EC) is factory set to “sequential start ON.”
