  • Page 53: Auto Restart

    14. 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 started with the memorized operation contents. When the power is interrupted and recovered during timer operation, since the timer operation time is shifted by the time the power was interrupted, an alarm is given by blinking (7 sec ON/2 sec OFF) the indoor unit body timer lamp.

  • Page 54: Compressor Preheating

    17. COMPRESSOR PREHEATING When the outdoor heat exchanger temperature is lower than -4°C and the heating operation has been stopped for 30 minutes, 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 -2°C or greater, preheating is ended.
