1. Safety Protection
(1) Time Delay for Safety protection
z3 minutes delay for compressor ---The compressor is ceased for 3minutes before restarting to
balance the pressure in the refrigeration cycle in order to protect the compressor.
z2 minutes delay for 4-way valve---The 4-way valve will be ceased for 2 minutes late after
compressor to prevent the refrigerant-gas abnormal noise when the HEATING operation is
OFF or switch to the other operation mode.
(2) Discharge temperature protection
There is a temperature sensor on top of compressor, when temperature on top of
compressor
exceeded the limit, system control will shut down the compressor and the display board will
show the error code.
(3) Lower voltage protection
When AC voltage ≤158V and keep it for 10 seconds, unit will be shut down for protection.
(4) Over voltage protection
When AC voltage ≥260V, unit will be shut down and recover while AC≤255V.
(5) Over current protection
When the current of outdoor unit is overload, controller shut down the unit immediately and show
error code.
(6) Compressor abnormity protection
When compressor start on or in the process of running, if there is no feedback to controller or
load of compressor is abnormity, the air conditioner will shut down, and show error code.
(7) IPM module protection
IPM module has high temperature & over current protection itself, if there is signal feedback to
IPM, the outdoor unit will shut down, LED on outdoor PCB will show the error code.
2. “Feel” Mode Operation
(1) When the “Feel” mode is selected, the operation mode and initial temperature set are
determined by the initial room temperature at start-up of the operation except to turn off the air
conditioner and operates it again.
(2) If the mode is change to “Feel” from other mode, the “Feel” mode doesn’t operate until
compressor stop for more than 3 minutes.

Mode Initial Room Temperature Initial Set Temperature
COOLING RT=26℃23℃
DRY 26℃>RT≥20℃RT-2℃
HEATING for Heat Pump/
FAN for Cooling Only RT<20℃-

zIn the “Feel” mode, when the controller receives the up or down signal of temperature, the set
temperature can adjust by 1℃upper or lower. The biggest you can adjust by 2℃upper or lower.

3. “COOLING” Mode Operation
(1) Compressor frequency control
According to difference room temperature and set temperature (δt = RT-ST), running frequency of
compressor is controlled by electronic controller. When room temperature is much higher than set
temperature, the compressor will start at a high frequency, and as room temperature goes down, the
compressor running frequency will go down. When room temperature is lower than set temperature,


6

thecompressor will run at very low frequency. In general, unit will change its running frequency
according toδt to make room temperature closing to set temperature.
(2) Outdoor temperature affects running frequency of the compressor
Outdoor temperature affect compressor’s running frequency. Difference inlet temperature of
outdoor unit is adapted by difference compressor running frequency. While outdoor temperature is
about 30℃, the compressor will run in high frequency.
If unit run in “cooling” mode and outdoor temperature is less than -2℃,the controller will shut down
compressor and show error code, while the ambient temperature is over 1℃, the compressor will run
automatically.
(3) Auto fan control in cooling mode
In cooling mode (include cooling in “feel” mode), fan speed is determined by
δ t, as the following

4.“DRY” Mode Operation
(1) The system for DRY operation used the same refrigerant circle as the cooling one.
(2) When the system operates in DRY mode, at first it operates in cooling mode, the set
temperature (ST) is “RT-2℃”. After that, t he system will operate in cooling mode with lowest
fan speed for 30 minutes and then change to middle speed for 30seconds as a cycle. During
the course of this operation, you can’t use remote controller to adjust the fan speed but you can
control the vane direction.
(3) In the dry mode, when RT≤12℃, the compressor will stop and operates again at RT≥14℃.
5. “HEATING” Mode Operation (available for Heat Pump only)
(1) Frequency control
Same as the frequency control in cooing mode, the running frequency of compressor is
controlled by controller. Unit change its running frequency according to
δ t to make the room
temperature closing to the set temperature.
(2) Indoor fan motor control
1) Cold Air Prevention Control
zThe function is intended to prevent cold air from being discharged when heating mode
selected or while in defrosting.
zThe indoor fan speed will be controlled as following.

(3) 4-way valve control
In heating mode, 4-way valve will power on ahead of compressor for 5 seconds, and cut off
for 2 minutes later than compressor. 4-way valve will not power off unless the machine to be
switched off, mode changed or on the process of defrosting.
(4) Defrosting
Defrosting is controlled by the microprocessor.
When one of the following conditions is satisfied, unit comes into defrosting:
a. Outdoor heat exchanger Temperature (OPT) is continuously less than 3℃while the unit runs
for more than 40 minutes, and OPT is keeping under -6℃for more than 3 minutes.
b. Outdoor heat exchanger Temperature (OPT) is continuously less than 3℃meanwhile the
unit runs for more than 80 minutes, and OPT is keeping under -4℃for more than 3
minutes.
c. Outdoor heat exchanger Temperature (OPT) is continuously less than 3℃while the unit runs
for more than 120 minutes, and OPT is keeping below -2℃for more than 3 minutes.
Before the air con comes into defrosting, compressor running frequency drop down to a
lower frequency firstly, then the compressor shuts down.
In defrosting, the max. frequency of compressor is F9 (a little less than the highest
frequency ). In this period all protection function are available.
