12. AUTO RESTART

When the power was interrupted by a power failure, etc. during operation, the operation contents
at that time are memorized and when power is recovered, operation is automatically resumed with
the memorized operation contents.
When the power is interrupted and recovered during timer operation, timer operation is canceled,
but only setting time is memorized.

14. COMPRESSOR PREHEATING

When the outdoor heat exchanger temperature is lower than Operation temperature (Refer to Table 6)
and the heating operation has been stopped for 3 hours, power is applied to the compressor and
the compressor is heated.
(By heating the compressor, warm air is quickly discharged when operation is started.)
When operation was started, and when the outdoor temperature rises to Release temperature or greater,
preheating is over.
