and the unit will operate as previous operation condition.
2.2.2. Total Running Current Control (Page: 28)
1. When the total outdoor unit running current (AC) exceeds X value, the frequency instructed for compressor operation will be
decreased a step to smaller frequency number.
2. If the running current does not exceed X value for five seconds, the frequency instructed will be increased a step at one time
to bigger frequency number.
2.2.3. IPM (Power transistor) Prevention Control (Page: 29)
A. DC Peak Current Control
1. When electric current to IPM exceeds set value of 22.5 ± 3.5 A, the compressor will stop operate. Then, operation will restart
after three minutes.
2. If the set value is exceeded again within 30 seconds after the compressor starts, the operation will restart after one minute.
If this condition repeats continuously for seven times, all indoor and outdoor relays will be cut off.
