In heating operation, the freeze-preventive control works if 4-way valve is not exchanged and the condition is satisfied. (However the temperature for J zone dashing control is changed from 2°C to –5°C.)

8 High-temp	1) The heating operation is performed as follows based on
release control	the detected temperature of Tc sensor or Tcj sensor.
	•	When [M] zone is detected, the commanded fre-
		quency is decreased from the real operation fre-
		quency. After then the commanded frequency
		changes every 30 seconds while operation is per-
		formed in [M] zone.
	•	In [N] zone, the commanded frequency is held.
	•	When [L] zone is detected, the commanded fre-
		quency is returned to the original value by approx.
		6Hz every 60 seconds.
