"STAND BY"
Displayed from the start of heating operation until the moment warm air blows
out.
Caution:
• When the air-conditioner is used together with burners, thoroughly venti-
late the area. Insufficient ventilation can result in accidents due to oxy-
gen deficiency.
• Never place a burner at a place where it is exposed to the airflow from
the air-conditioner.
Doing so can result in imperfect combustion of the burner.
• The microcomputer functions in the following cases: *
• Air does not blow out when heating starts. *
- To prevent any cool air from escaping, the indoor fan is gradually switched
in sequence from faint airflow/weak airflow/set airflow according to the tem-
perature rise of the blown out air. Wait a moment until the airflow comes out
naturally.
• The fan is not moving at the set speed. *
- In some models, the system switches over to faint airflow when the temper-
ature of the room reaches the set temperature. In other cases, it stops to
prevent any cool air from escaping during the defrosting operation.
• Air flows out even if operation is stopped. *
- Approximately 1 minute after the stop of operation, the indoor fan some-
times rotates to eliminate extra heat generated by the electric heater, etc.
The fan speed comes to low or high.
* Except PEFY-P-NMHU-E-F.
