The temperature setting range is 16 ℃～ 32 ℃
a)Primary setting temperature is 20 ℃， setting fan speed is middle fan ， press” plus” and“minus”button
to adjust the setting temperature. Press the “fan speed” button to select the setting fan speed among the
low fan, middle fan and high fan speed.
b)The characteristic of control
：
TA － TS ≤ － 1 ℃， compressor and outdoor fan unit start.
TA － TS ≥ 1 ℃， compressor and outdoor fan unit stop.
TA ＝ TS ， remain the previous condition.
c) The four-way valve keep open (except the defrosting condition)when running under the heating
mode. When transforming from the heating mode to the other mode or the air-conditioner turns off
with electricity, the four-way valve turns off in 2minutes delay.
d) Anti-cold air function and residual-heat removal function
Indoor fan unit control
： The indoor fan unit is controlled according to the setting temperature, indoor
room temperature and indoor coil temperature.
☆ When compressor runs ：
A 、 when TE ≥ TE1 ， the indoor fan unit runs at the setting fan speed. If the temperature rise up to
TE1 and fall down again, the low fan speed can be restored after the temperature reach TE1-5.
B 、 when TE2 ≤ TE ＜ TE1 ， the indoor fan unit runs at the low fan speed. If the temperature rise up
to TE2 and fall down again, the fan stops only after the temperature reach TE2-2.
C 、 When TE ＜ TE2 ， the indoor fan doesn’t start, hereafter if the coil temperature ≥ TE2 ， the fan
restore to the normal working condition.
D 、 If the indoor fan unit stop running for over than 10 minutes ， the “heating” indication light on
the operation panel twinkles.
☆ When compressor stop running ：
A 、 If TE ≥ TE3 ， the indoor fan unit runs at the setting fan speed.
B 、 If TE4 ≤ TE ＜ TE3 ， the indoor fan unit runs at low fan speed.
C 、 If TE ＜ TE4 ， the indoor fan unit stops running.
☆ When heating turns off ：
A 、 If TE ≥ TE5 ， the indoor fan unit runs at the low fan speed for 30 seconds.
B 、 Detect TE 30 seconds later, If TE still ≥ TE5 ， the indoor fan unit runs at low fan speed and to
be closed until TE ＜ TE5.
● Ventilation mode
a)When ventilating
，
only display the indoor temperature but without the setting temperature and its
display.
b)When ventilating
，
the temperature setting “plus” and ”minus” are invalid, the functions of strong fan
