Your air conditioner may be subject to any change owing to the improvement of JCI products. VRF series multiple air conditioning systems adopt the consistent running mode, by which, all indoor units can only be heating or refrigerating operation at the same time. To protect the compressor, the air conditioning unit should be powered on for over 12 hours before using it. All indoor units of the same refrigerating system should use the unified power switch to ensure that all indoor units are in the state of being powered on at the same time during the operation of air conditioner.
