Remarks
Value in the parentheses indicates one when thermostat of
the remote controller works.
Value without parentheses indicates one when thermostat
of the body works.
• If the air speed has been changed once, it is not
changed for 1 minute. However when the air speed is
exchanged, the air speed changes.
• When heating operation has started, the air speed
selects a upward slope, that is, the high position.
• If the temperature is just on the difference boundary, the
air speed does not change.
• Mode in the parentheses indicates one in automatic
heating operation.
• In Tc
≥
60°C, the air speed increases by 1 step.

3) In heating operation, the mode changes to [UL] if
thermostat is turned off.
4) If Ta
≥
25°C when heating operation has started and
when defrost operation has been cleared, it operates
with HIGH (H) mode or (HH) for 1 minute from when Tc
has entered in E zone of cool air discharge preventive
control (Item 6).
5) In automatic cooling/heating operation, the revolution
frequency of [HH] is set larger than that in the standard
cooling/heating operation. However the revolution
frequency is restricted in the automatic heating opera-
tion as shown in the following figure.
