Indoor Fan Motor Control - Toshiba ras-m16g3dv-e Service Manual

Item
1) Operation with (HH), (H+), (H), (L+), (L) or [AUTO] mode is carried
2. Indoor fan
motor out by the command from the remote controller.
control
2) When the air speed mode [AUTO] is selected, the air speed varies
by the difference between Ta and Ts.
<COOL>
• Controlling operation in case when thermo of remote controller works
is same as a case when thermo of the body works.
• If the air speed has been changed once, it is not changed for
3 minutes. However when the air volume is exchanged, the air speed
changes.
• When cooling operation has started, select a downward slope for the
air speed, 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 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 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, select an upward slope for the
air speed, 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.
