INFORMATION
CAPABILITIES
Heating Capability
• This room air conditioner utilizes a heat pump system that absorbs
exterior heat and brings it into a room to be heated. As the ambient
temperature gets lower, heating capability will also lower. In such a
situation, the PAM and inverter work to increase compressor rpm to keep
the unit's heating capability from decreasing. If the unit's heating
performance is still unsatisfactory, other heating appliances should be
used to augment this unit's performance.
• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer
operation is recommended for effective preheating ahead of the desired time.
