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.

Tc: Indoor heat exchanger sensor temperature
3) In heating operation, the mode changes to [UL] if thermo-
stat 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 fre-
quency is restricted in the automatic heating operation as
shown in the following figure.
