When another indoor unit is performing the heating (cooling) operation, the cool-
ing (heating) operation is not performed.
Because of the control operation of auto vane, it may change over to horizontal
blow automatically from the downward blow in cooling in case the downward
blow operation has been continued for 1 hour. At defrosting in heating, hot adjust-
ing and thermostat OFF, it automatically changes over to horizontal blow.
Ultra-low speed operation is commenced at thermostat OFF.
Light air automatically changes over to set value by time or piping temperature at
thermostat ON.
The fan is to stop during defrosting.
Fan is to run for 1 minute after stopping to exhaust residual heat (only in heating).
Ultra low-speed operation for 5 minutes after SW ON or until piping temperature
becomes 35°C, low speed operation for 2 minutes thereafter, and then set notch
is commenced. (Hot adjust control)
When the outdoor unit is being cooled and the refrigerant is resting, warming up
operation is performed for at least 35 minutes to warm the compressor.
During this time, only the fan operates.
System is being driven.
Operate remote controller again after "HO" disappear.
After a stop of cooling operation, unit continues to operate drain pump for three
minutes and then stops it.
Unit continues to operate drain pump if drainage is generated, even during a
stop.
