When system enters diagnostics mode, only one fault code is shown. Order of priority is from
the lower to the higher number. Diagnostics is continuously ON as long as power is ON. The
current system operation mode will not be changed.
If no fault occurred in the system, no fault code will be displayed during normal operation
mode. The last fault code will be displayed even if the system has recovered from that
fault. The last fault will be deleted from the EEPROM after the system has exit diagnostics
mode.
In diagnostics mode, system fault / status will be indicated by blinking of Heat & Cool LEDs.
The coding method will be as follows:
Heat LED will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds. Cool

Simple procedures for checking the Main Parts
11.5.1
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).
11.5.2
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.
11.5.3
Checking the Outdoor Fan Motor.
Enter Test Mode (where the OFAN speed is high)
Check the voltage between lead wires according to the normal value as following:
•
•
•
11-6
Between red wire and black wire: 310VDC +/- 20V
Between orange wire and black wire: 15VDC +/- 1V
Between yellow wire and black wire: 2-6VDC
CONTENT
SM SX DCI 1-A.3 GB
TROUBLESHOOTING
11.5.4
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 below 0.5 ohm
(TBD).
11.5.5
Checking the Reverse Valve (RV).
Running in heating mode, check the voltage between two pins of reverse valve connector,
normal voltage is 220VAC.
11.5.6
Checking the electrical expansion valve (EEV).
The EEV has two parts, drive part and valve. The drive part is a step motor; it is ringed on the
valve. Check the drive voltage (12VDC). When Outdoor unit is power on, EEV shall run and
have click and vibration.
11.6
Precaution, Advise and Notice Items
11.6.1
High voltage in Outdoor unit controller.
Whole controller, including the wires that are connected to the Outdoor unit controller may
have the potential hazard voltage when power is on. Touching the Outdoor unit controller may
cause an electrical shock.
Advise: Don’t touch the naked lead wire and don’t insert finger, conductor or anything else into
the controller when power is on.
11.6.2
Charged Capacitors
Three large-capacity electrolytic capacitors are used in the Outdoor unit controller. Therefore,
charging voltage (380VDC) remains after power down. Discharging takes about four minutes
after power is off. Touching the Outdoor unit controller before discharging may cause an
electrical shock.
11.6.3
w
Additional advises
•
•
When disassemble the controller or the front panel, turn off the power supply.
•

12.1
General Functions and Operating Rules
The DCI software is fully parametric.
All the model dependent parameters are shown in Blue color and with Italic style [parameter].
The parameters values are given in the last section of this control logic chapter of the service
manual.
12.1.1
System Operation Concept
The control function is divided between indoor and outdoor unit controllers. Indoor unit is the system
‘Master’, requesting the outdoor unit for cooling/heating capacity supply. The outdoor 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.
The capacity request is transferred via indoor to outdoor communication, and is represented by
aparameter called ‘NLOAD’. NLOAD is an integer number with values between 0 and 127, and it
represents the heat or cool load felt by the indoor unit.
12.1.2
Compressor Frequency Control
12.1.2.1 NLOAD setting
The NLOAD setting is done by the indoor unit controller, based on a PI control scheme.
The actual NLOAD to be sent to the outdoor unit controller is based on the preliminary LOADcalculation,
the indoor fan speed, and the power shedding function.

Step 1
Whenever the compressor starts up, after it has been off for more than 45 minutes, the compressor
frequency cannot go below Step1RPS for 3 continuous minutes (this rule comes to ensure oil return
to the compressor).
Step 2
The compressor speed cannot go above Step2RPS once after each compressor start up for 3
continuous minutes (this rule comes to prevent oil exit from the compressor after its start up).
Step 3
The speed cannot go higher than Step3RPS unless it was operating for more than 1 continuous
minutes between Step3RPS – 5 and Step3RPS .
After passing above Step3RPS, this rule is re-applied when passing below Step3RPS-5.

Indoor Fan Control
8 Indoor fan speeds are determined for each model. 4 speeds for cool/dry/fan modes and 4 speeds
for heat mode.
When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate constantly
at set speed.
When Auto Fan is selected, indoor unit controller can operate in all speeds. The actual speed is set
according to the cool/heat load.
12.1.7.1 Turbo Speed
The Turbo speed is activated during the first 30 minutes of unit operation when auto fan speed is
selected and under the following conditions:
Difference between set point and actual room temperature is bigger then 3 degrees.
Room temperature > 22 for cooling, or < 25 for heating.
12.1.8
Outdoor Fan Control
12.1.8.1 Outdoor Fan Control for DCI50/60
7 outdoor fan speeds are determined for each model. 3 speeds for cool and dry modes, and 3
speeds for heat mode, and a very low speed.
Outdoor fan speed is a function of compressor frequency and outdoor air temperature (OAT).
4 routines for fan control are determined. The control routine selection depends on operation mode,
compressor speed, outdoor air temperature (OAT) and heat sink temperature (HST).

EEV (Electronic Expansion Vavle) Control
12.1.9.1 EEV Control for GC 9, 12, 18 DCI
EEV opening is defined as EEV = EEVOL + EEVCV
EEVOL is the initial EEV opening as a function of the compressor frequency, operation mode, unit
model and capacity.
EEVCV is a correction value for the EEV opening that is based on the compressor temperature.
During the first 5 minutes of compressor operation EEVCV = 0.
Once the first 5 minutes are over, the correction value is calculated as follow: EEVCV(n) =
EEVCV(n-1) + EEVCTT
EEVCTT is the correction based on the compressor temperature. A target compressor temperature
is set depending on frequency and outdoor air temperature, and the actual compressor temperature
is compared to the target temperature to set the required correction to the EEV opening.

Cool Mode
NLOAD is calculated according to the difference between actual room temperature and user set
point temperature by PI control.
In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed.
In AutoFan user setting, fan speed will be adjusted automatically according to the calculated
NLOAD.
12.4
Heat Mode
NLOAD is calculated according to the difference between actual room temperature and user set
point temperature by PI control.
In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed.
In AutoFan user setting, fan speed will be adjusted automatically according to the calculated
NLOAD.
12.4.1
Temperature Compensation
In wall mounted, ducted, and cassette models, 3 degrees are reduced from room temperature
reading (except when in I-Feel mode), to compensate for temperature difference between high and
low areas in the heated room, and for coil heat radiation on room thermistor.
The temperature compensation can be enabled/disabled by shortening of J2 on the indoor unit

12.5
Auto Cool/Heat Mode
When in auto cool heat mode unit will automatically select between cool and heat mode according
to the difference between actual room temperature and user set point temperature (.T). Unit will
switch from cool to heat when compressor is off for 3 minutes, and .T < -3.
Unit will switch from heat to cool when compressor is off for 5 minutes, and .T < -3.

12.6
Dry Mode
As long as room temperature is higher then the set point, indoor fan will work in low speed and
compressor will work between 0 and MaxNLOADIF1C Hz.
When the room temperature is lower than the set point, compressor will be switched OFF and indoor
fan will cycle 3 minutes OFF, 1 minute ON.
12.7
Protections
There are 5 protection codes.
Normal (Norm) – unit operate normally.
Stop Rise (SR) – compressor frequency can not be raised but does not have to be decreased.
HzDown1 (D1) – Compressor frequency is reduced by 2 to 5 Hz per minute.
HzDown2 (D2) – Compressor frequency is reduced by 5 to 10 Hz per minute.
Stop Compressor (SC) – Compressor is stopped.
