1. When room temp-set temp ≤-3.6°F , cooling will stop;
Outdoor fan will stop later and indoor fan will operate at set
speed;
2. When room temp –set temp
˚
-3.6°F, if such situation
continues for a period of time, cooling operation will be
started. In that case, indoor fan, outdoor fan and
compressor will operate and the indoor fan will operate at
set speed.
* In this mode, fan and swing motor will operate at set status
and the temp range setting is 61~86°F.
* If there is malfunction of outdoor unit or the unit stops for
protection, the indoor unit will keep its operation status but the
error will be displayed.
(2)Dry Mode
1. In this mode, the fan motor runs at low fan speed while swing
works according to setting state. The range of setting temperature
is 61~86°F.
2. When outdoor unit has malfunction or stopped for protection,
the indoor fan will keep the original running state and the error will
be displayed.
(3)Fan Mode
1. In this mode, the indoor fan may run at high, medium, low and
automatic speed. The compressor, outdoor fan and 4-way valve all
stop running.
2. In this mode, the range of setting temperature is
61~86°F.
(4)Heat Mode
1.Heating mode
When setting temperature-indoor temperature≤ 29.3°F.the unit will
stop heating. Both outdoor fan and indoor fan will stop later.
When setting temperature-indoor temperature>29.3°F and it lasts
for a certain period, the unit will start heating. In that case, indoor
fan, outdoor fan and compressor will start running. The indoor fan
works according to the anti-cold air.
* In this mode, the range of setting temperature is
61~86°F.
2.Protection function: in heating mode, when the compressor stops
as a result of malfunction, the indoor fan blows residual heat.
3.Defrosting control: when the defrosting signal is revived,defrosting

*Anti-cold air function
The rotational speed of indoor electromotor is decided based on
the indoor pipe temperature. The indoor fan can run at low speed
or stop running. This function will terminate after the unit runs for
3min or the pipe temperature reached certain value.
During heating, if the indoor pipe temperature is lower than certain
value.The running speed of indoor fan will decrease automatically
base on the pipe temperature and ensure that the outlet air is hot.
During heating, when the stopping condition for the compressor is
reached,the compressor and the outdoor fan motor stop running
fan will stop after running for 60s at setting speed.
In this mode, the system selects the operation mode (cooling and
