13 Protection Control
13.1. Protection Control For All Operations
13.1.1. Restart Control (Time Delay Safety Control)
• The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on again by
pressing OFF/ON button at remote control within this period.
• This control is not applicable if the power supply is cut off and on again.
• This phenomenon is to balance the pressure inside the refrigerant cycle.
13.1.2. 30 Seconds Forced Operation
• Once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation although the intake air
temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON button at the remote
control is permitted or the Auto OFF/ON button at indoor unit.
• The reason for the compressor to force operation for minimum 30 seconds is to allow the refrigerant oil run in a full cycle and
return back to the outdoor unit.
13.1.3. Total Running Current Control
1. When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor operation will be
decreased.
2. If the running current does not exceed X value for five seconds, the frequency instructed will be increased.
3. However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for 3 minutes.
4. The first 30 minutes of cooling operation, (A) will be applied.
