Compressor will stop when CTT reaches 110C
If the unit stops as such protection for 6 times (the counter will be cleared after the compressor has

Compressor over Current Protection
Detect an input current by the CT during the compressor is running, and set the frequency upper limit
from such input current. In case of heat pump model, this control is the upper limit control function of
the frequency which takes priority of the lower limit of four way valve activating compensation.
Detail
For model 14: Compressor will stop when AC current >= 16.0A for continuously 2.5s
For model 18/30: Compressor will stop when AC current >= 20.0A for continuously 2.5s
If the unit stops as such protection for 6 times (the counter will be cleared after the compressor has

12.7.6
Outdoor Coil Deicing Protection
This protection is for Heat Pump Only
This protection is carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor heat
exchanger temperature must be more than its setting values when finishing the deicing protection.
In the deicing protection, IFAN is forced OFF.
12.7.6.1 Deicing Starting Conditions
The starting conditions must be made with the outdoor air temperature (OAT) and outdoor coil
temperature (OCT). Under the conditions that the system is in heating operation, after the time
for defrosting is judged to be satisfied, if the temperature for deicing is satisfied after detections
for continuous 1 minute, the deicing operation will start.
Deicing interval time is changed as a function of deicing time. If deicing time is shorter than
former deicing time, the deicing interval time will be increased. If deicing time is longer than
former deicing time, the deicing interval time will be decreased.

Connected IDU number detection
If ODU does not receive correct signal from one IDU for 3min continuously, the ODU will take this
IDU as not connected one. But ODU will still send the broadcast to this IDU. If response were
received, then ODU will take it as connected.
12.7.8
IPM module protection
When the compressor starts, if there is over current or control voltage low for IPM module as some
abnormal results, IPM will detect module protection signal as the unit is on. Once the module
protective signal is detected, stop the unit with module protection immediately. If the module protection
is resumed and compressor has stopped for 3min, the unit will be allowed to operate.
If the module protection continuously occurs for 6 times (the counter will be cleared after the
compressor has run for 7min), it can not resume running automatically and display malfunction, it
can resume by power reset.

If the HP switch is opened for 3S continuously, the system will stop as protection
After the HP switch protection, if HP switch is resumed for continuous 6s, the system operating can
be resumed by power reset.

Module overheating protection
If the module temperature is higher than 95C, the unit will stop. If module temperature is lower than
95C, and compressor has stopped for 3min, the unit will resume operating.

Precautions before Performing Inspection or Repair
Be cautious during installation and maintenance. Do operation following the regulations to
avoid electric shock and casualty or even death due to drop from high attitude.
* Static maintenance is the maintenance during de-energization of the air conditioner.
For static maintenance, make sure that the unit is de-energized and the plug is disconnected.
*Dynamic maintenance is the maintenance during energization of the unit. Before dynamic
maintenance, check the electricity and ensure that there is ground wire on the site. Check
if there is electricity on the housing and connection copper pipe of the air conditioner with
voltage tester. After ensure insulation place and the safety, the maintenance can be performed.
Take sufficient care to avoid directly touching any of the circuit parts without first turning off
the power. At time such as when the circuit board is to be replaced, place the circuit board
assembly in a vertical position. Normally, diagnose troubles according to the trouble diagnosis
procedure as described below.(Refer to the check points in servicing written on the wiring
diagrams attached to the indoor/outdoor units.)
Precautions when inspecting the control section of the outdoor unit:
A large-capacity electrolytic capacitor is used in the outdoor unit controller (inverter).Therefore,
if the power supply is turned off, charge(charging voltage DC280V to 380V)remains and
discharging takes a lot of time. After turning off the power source, if touching the charging
section before discharging, an electrical shock may be caused.
The outdoor unit can not be started up until the unit is de-energized for 20min
13.1.2
Confirmation
13.1.2.1 Confirmation of Power Supply Confirm that the power breaker operates(ON) normally;
13.1.2.2 Confirmation of Power Voltage Confirm that power voltage is AC220~240V +/- 10%.
If power voltage is not in this range, the unit may not operate normally.

Checking system pressures and other thermodynamic measures should be done when system
is in Test Mode (in Test mode, system operates in fixed settings). The performance curves
given in this manual are given for unit performance in test mode when high indoor fan speed
is selected.
Entering test mode please refer to section 12- Control system.
13.2
Simple procedures for checking the Main Parts
13.2.1
Checking Mains Voltage.
Confirm that the Mains voltage is between 198 and 264 VAC. If Mains voltage is out of this
range, abnormal operation of the system is expected. If in range check the Power (Circuit)
Breaker and look for broken or loosed cable lugs or wiring mistake(s).
13.2.2
Checking Power Input.
If Indoor unit power LED is unlighted, power down the system and check the fuse of the Indoor
unit. If the fuse is OK replace the Indoor unit controller. If the fuse has blown, replace the fuse
and power up again.
Checking Power Input procedure for the Outdoor unit is the same as with the Indoor unit.
13.2.3
Checking the Outdoor Fan Motor.
Check the voltage between any two pins of connector OFAN on controller, normal voltage is
280~380VDC
13.2.4
Checking the Compressor.
The compressor is brushless permanence magnetic DC motor. Three coil resistance is same.
Check the resistance between three poles. The normal value should be with the almost same
value. Pay attention U,V, W are respective to connect to RED,YELLOW,BLUE wires.
13.2.5
Checking the Reverse Valve (RV).
Running in heating mode, check the voltage between two pins of reverse valve connector,
normal voltage is 220VAC.
