Fan speed control
Outline of specifications
1) Operation with (HH), (H), (L) or [AUTO] mode is carried
out by the command from the remote controller.
2) When the fan speed mode [AUTO] is selected, the fan
speed varies by the difference between Ta and Ts.
<COOL>
• Controlling operation in case when thermostat of remote
controller works is same as a case when thermostat of the
body works.
• If the fan speed has been changed once, it is not changed
for 3 minutes. However when the air volume is exchanged,
the fan speed changes.
• When cooling operation has started, select a downward
slope for the fan speed, that is, the high position.
• If the temperature is just on the difference boundary, the
fan speed does not change.
• Mode in the parentheses indicates one in automatic
cooling operation.
<HEAT>
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 fan speed has been changed once, it is not changed
for 1 minute. However when the fan speed exchanged, the
fan speed changes.
• When heating operation has started, select an upward
slope for the fan speed, that is, the high position.
• If the temperature is just on the difference boundary, the
fan speed does not change.
• Mode in the parentheses indicates one in automatic
heating operation.
• In Tc ≥ 60°C, the fan speed increases by 1 step.
