12.1.2 System Operation Concept
The control function is divided between indoor and outdoor unit controllers. Outdoor unit is the system
‘Master’, requesting the indoor unit for cooling/heating capacity supply. The indoor unit is the system
‘Slave’ and it must supply the required capacity unless it enters into a protection mode avoiding it from
supplying the requested capacity.
Target frequency is transferred via indoor to outdoor communication, and the calculation is based on
room temperature and set point temperature.
12-2
CONTROL SYSTEMS
12.1.3 Compressor Frequency Control
The Compressor Frequency Control is based on the PI scheme.
When starting the compressor, or when conditions are varied due to the change of the room
condition, the frequency must be initialized according to the ΔD value of the indoor unit and the Q
value of the indoor unit.
Q value: Indoor unit output determined from indoor unit capacity, air flow rate and other factors.
1. P control
Calculate ΔD value in each sampling time (20 seconds), and adjust the frequency according to its
difference from the frequency previously calculated.
2. I control
If the operating frequency is not change more than a certain fixed time, adjust the frequency up and
down according to the ΔD value.
Obtaining the fixed ΔD value
When the ΔD value is small- decrease the frequency
When the ΔD value is large- increase the frequency
3. Frequency management when other controls are functioning
When frequency is drooping;
Frequency management is carried out only when the frequency droops.
For limiting lower limit
Frequency management is carried out only when the frequency rises.
4. Maximum and minimum limits of frequency by PI control
The frequency upper and lower limits are set depending on indoor unit.
When low noise commands come from the indoor unit or when outdoor unit low noise or quiet
commands come from indoor unit, the upper limit frequency must be lowered than the usual setting.
(see 12.1.3.1)
12.1.3.1 Frequancy range
The compressor frequency limitation is set by the following table

CONTROL SYSTEMS
12.1.5.2 Compressor Starting Control
When turning the compressor from OFF to ON, the upper limit of frequency must be set as follows.
(The function must not be used when defrosting.)
12.1.5.3 Minimum On and Off Time
Prohibit to turn ON the compressor for 3 minutes after turning it off.(except during deicing protection)
12.1.6 Indoor Fan Control
8 Indoor fan speeds are determined for each model. 4 speeds for COOL modes and 4 speeds for

13.1 ELECTRICAL & CONTROL TROUBLESHOOTING
13.1.1 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.

SM HDDE 1-A.1 GB
13.1.4 Checking the refrigeration system
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.
For AC motor
Check the voltage between two pins Hi and N of connector OFAN on controller, normal
voltage is 220~240VAC.
For DC 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 220~240VAC.
