Needless use of the supplementary heat reduces potential energy savings. 2. Ice or frost tends to form on the coil during winter heating operation. Your unit is designed to automatically melt the ice. When in this defrost cycle, it is normal for steam or fog to rise from the outdoor unit, and for water to drain from the outside of unit.

If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat absorbed from the outside air. So, to maintain energy-efficient operation. your unit has an automatic defrost mode. The defrost mode starts at a preset time interval of 30 minutes, although, it may be reset to 60, 90 or 120 minutes. Defrost will start at the preset time only if the ice is sufficient to interfere with normal heating operation.
