❋
Defrost mode will start when the temperature difference between outdoor and outdoor heat exchanger has become
more than certain standard.
❋
Factory default status is MID. When the function changes to LOW with option control, defrost entering temperature
decreases. When defrost entering temperature decreases, the operation hour will be long but this means that the
operation hour with the reduced heating capacity increases. This option is used at places where humidity is high and the
defrost mode enters too frequently.
❋
Maintaining factory default status is recommended.
