and mild operation is performed by reducing the fan speed and
the compressor speed.
<Cooling operation>
This function operates the air conditioner with the difference
between the set and the room temperature as shown in the
following figure.
The time correction is performed for 8 minutes each.
(However, the first correction is performed 150 seconds after
start of the operation.)
Description
<Cooling operation>
1) The room temperature (Tao) at
the start time of DRY operation is
detected.
2) According to difference between
the room temperature and the
set temperature (Tsc), the
operation starts with the condi-
tions shown in the left figure.
Set temp.
(Tsc) = Set temp. on remote
controller (Ts) + (0.0 to 1.0)
3) If the room temperature is down
by 2°C or more, turn off the
compressor.
<Heating operation> <Heating operation>
1) The indoor fan speed is con-
trolled within (W7) as maximum
value.
2) Setting the compressor speed to
Max. 52Hz, the temperature zone
in which the operation can be
performed with Max. 16Hz is
gradually widened after 30
minutes passed when starting
ECO operation.
3) The louver position is set
horizontally (Standard cooling
position) when the room tem-
