When the outdoor unit is installed above the indoor unit an oil trap is required every 5m along the suction
line at the lowest point of the riser. Incase the indoor unit is installed above the outdoor, no trap is
required.
*Applicable for DLS18 only, for DLS24 – 44 oil traps are not required.

CONTROL SYSTEM
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
12.1.2.1
Compressor Frequency Control
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.
NLOAD limits as a function of indoor fan speed:
12.1.3
12.1.3.1
Target Frequency Setting
Target Frequency Setting for GCD 030
During normal operation (excluding protections) the compressor target frequency is set according to
the ODU NLOAD number received from the indoor unit.
For single split channel the ODU NLOAD = IDU NLOAD

Frequency Changes Control
When the unit is running normally , the compressor frequency change rate is 1 Hz/sec.
12.1.5
12.1.5.1
Compressor Starting Control
Compressor starting control for GCD 030
When started, compressor frequency must reach 30 Hz, and not go down below 30 Hz during the
first 5 minutes of compressor operation, except when compressor should be stopped (see next
sections for explanation).
When Reaching Step1Freq Hz and Step2Freq Hz (for the first time during one continuous compressor
operation) during compressor acceleration, compressor acceleration will be stopped for one minute
and then continue.
Note: If compressor is working constantly at a frequency between the step frequency and step
frequency – 10 Hz, then it will remain in its current frequency until one minute is over. After that
minute is over, there is no need to stop compressor acceleration again at the step frequency.
When compressor frequency is equal or higher than Step2Freq Hz, further increasing of compressor
frequency will be done in steps of HzDown1 Hz every one minute.
The Normal acceleration/deceleration rate will be kept during these steps.
Decelartion does not require steps.
The steps limitation is ignored during Deicing protection.
This logic should be followed every time frequency should be increased over Step2Freq, and not
only once.
Compressor frequency can not go over Step3Freq Hz during the first 10 minutes of continues
compressor operation (excluding Deicing).
12.1.6
Minimum On and Off Time
3 minutes
12.1.7
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
12.1.8.1
Outdoor Fan Control
Outdoor Fan Control for DCI 80 Z
OFAN operates between OFMinRPM to OFMaxRPM.
The OFAN will be off when the compressor is off.
when compressor is OFF, and HST>55 or faulty, OFAN will remain ON in 500 rpm for up to three
minutes.
IF HST falls below 55, OFAN will be switched off immediately.

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

Outdoor Coil Deicing Protection
Outdoor coil Deicing Protection For GCD 030
● Entering Deicing Conditions
Deicing operation will start when either one of the following conditions exist:
Case 1: OCT < OAT – 8 AND TLD > DI
Case 2: OCT < OAT – 12 AND TLD > 30 minutes.
Case 3: OCT is Invalid AND TLD > DI
Case 4: Unit is just switched to STBY AND OCT < OAT – 8
Case 5: NLOAD = 0 AND OCT < OAT -8
Case 6: OCT<-4 AND TLD>100 minutes
All this condition will exist during 10 seconds
OCT – Outdoor Coil Temperature
OAT – Outdoor Air Temperature
TLD – Time from Last Deicing
DI – Deicing Interval (Time Interval Between Two Deicing)
Deicing interval time when compressor is first started in heat mode, is 10 minutes if OCT < -2, and
is 40 minutes in other cases.
Deicing interval time is changed (increased/ decreased in 10 minutes steps) as a function of deicing
time. If deicing time is shorter then former deicing time, the deicing interval time will be increased. If
deicing time is longer then former deicing time, the deicing interval time will be decreased.

13.1.3.1
Outdoor unit diagnostics
If any fault exists in the system, it will be shown according to tIf no fault exists in the system, no
fault code will be displayed during normal operation mode, and the status led will be on while the
compressor is enable.he following coding method.
Two LEDs display the system diagnostics on real time as follows:
STATUS LED is blinking 5 times in 5 seconds, and shut off for the next 5 seconds.
FAULT LED will blink during the same 5 seconds according to the following table:
13.1.3.1.1 LED’s Indicators - single split only
If any fault exists in the system, its fault will be shown according to the following coding method.
The last fault occurred in the system will be stored in the EEPROM.
If no fault exist in the system, no fault code will be displayed during normal operation mode.
When system enters diagnostics mode(through IDU communication), the last fault code will be displayed even
if the system has recover from that fault. The last fault will be deleted from the EEPROM after the system has
exit diagnostics mode (through IDU communication). The current system operation mode (cool/ heat/ off) will
not be changed when system enters diagnostics.
The coding method is as follow:
STATUS LED is blinking 5 times in 5 seconds, and shut off for the next 5 seconds.

Whenever this table is updated, the installation test procedure, and the alarm output function should be updated.
Only one code is shown.
Order of priority is 1-32. Diagnostics is continuously ON as long as power is on.
Heat Sink Over Heating Protection, Compressor Over Heating Protection, and System Over Power Protection are declared
only whenever in ‘Stop-Compressor’ status.
All faults, except the thermistor faults, will remain at least 10 seconds. This rule comes to serve the monitoring utilities, in
a case the fault is released quickly it will be still shown under the monitoring utilities.
Thermistor faults are reported only when they are enabled.
When the outdoor unit is in fault (not protection), an in-fault signal is sent to the indoor. When all the outdoor unit faults are
cleared, ‘no-fault’ signal is sent to the indoor.

Procedures for checking Main Parts
13.1.4.1
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).
13.1.4.2
Checking Main fuse
Check 20A fuse on the Filter Board - If burnt – check the compressor, fan or any other peripheral that
can cause a short. In case of a problematic peripheral - replace it.
In case no problematic peripheral, check the resistance on the DC bank (B+ & B- on the Power
board), if it is less than 30Ω, replace the controller. Otherwise replace the burnt fuse. In case of
frequent burning fuse, replace the controller.
13.1.4.3
Checking PFC Chock coil
Check PFC chock connection – repair if needed.
Dis-connect the chock from the controller wire extensions, check if the 2 wires of the chock are
shorted. If shorted (OK) check between each wire and the metal box. If shorted replace chock, if
not (OK), open the controller top cover and check if the wire extensions are connected well and if
shorted. If not shorted, replace wires, if shorted (OK) than might be a controller problem – replace
controller.

TROUBLESHOOTING
13.1.4.4
Checking the Outdoor Fan Motor
Check FAN-Power and FAN-Halls connections - Repair if needed.
Rotate the fan slowly by hand. If the fan does not rotate easily, check whether something is obstructing
the fan, or if the fan itself is coming into contact with the outer case, preventing it from rotating.
Correct if necessary - otherwise, the fan motor bearings have seized. Replace the motor.
If the fan rotates easily, use a current probe (“Clamp”) to assure AC current on each phase and it is
less than 1A.
In case there is no current, check the resistance between the three poles. Assure the three coil
resistances are almost the same.
The normal value should be between 10Ω to 20Ω.
Change to Stand-by or Power OFF and re-start - If the fault is still active - replace controller.
13.1.4.5
Checking the Compressor
Check Compressor connections - Repair if needed.
Use a current probe (“Clamp”) to assure that there is an AC current on each phase – no more than
15A.
In case there is no current, check the resistance between the three poles. Assure the three coil
resistances are almost the same (between 0.8Ω to 1.5Ω).
Change to Stand-by or Power OFF and re-start - If the fault is still “Active” - replace controller.
13.1.4.6
Checking the Reverse Valve (RV)
The RV has two parts, Solonoid and valve.
Solonoid - Running in heating mode, check the voltage between two pins of reverse valve connector,
normal voltage is 230VAC. if no power supply to RV, Check RV operation with direct 230VAC power
supply, if OK, replace outdoor controller.
Valve - if RV solonoid is OK (as above) but still no heating operation while compressor is On, replace
the valve.
13.1.4.7
Checking the electrical expansion valve (EEV)
The EEV has two parts, drive and valve.
When Outdoor unit is powered on, EEV shall run and have click and vibration.
For assuring the problem is of the EEV parts, perform the installation test and if fails and no other
indications in the diagnostics, than the problem is with the EEV (one or more).
Drive - a step motor; ringed on the valve. Check the drive voltage, should be12VDC.
Valve – if drive is OK (as above) but still the indoor unit perform no conditioning replace the valve (no
need to take out the refrigerant, just pump down and shut off the main valves).
13.1.4.8
Checking the termistors
Check Thermistor connections and wiring - Repair if needed.
Check Thermistor resistance – between 0ºC and 40ºC should be between 35KΩ and 5KΩ.
13.1.4.9
Checking the communication
Change to Stand-by or Power OFF and re-start - If the fault is still “Active” check Indoor to Outdoor.
Communication wiring and grounding connections (should be less than 2.0Ω) - Repair if needed.
If IDU failure – replace IDU controller that does not respond.
If ODU failure – replace ODU.

TROUBLESHOOTING
13.1.4.10 Checking for electromagnetic interferance (EMC problems)
13.1.4.10.1 EMC troubles to the A/C unit
Locations most susceptible to noise :
1. Locations near broadcast stations where there are strong electromagnetic waves.
2. Locations near amateur radio (short wave) stations.
3. Locations near electronic sewing machines and arc-welding machines.
Trouble :
Either of the following trouble may occur:
1. The unit may stop suddenly during operation.
2. Indicator lamps may flicker
Correction :
The fundamental concept is to make the system less susceptible to noise
(insulate for noise or distance from the noise source):
1. Use shielded wires.
2. Move unit away from the noise source.
13.1.4.10.2 EMC troubles to near by home appliances
Locations most susceptible to noise :
1. A television or radio is located near the A/C and A/C wiring.
2. The antenna cable for a television or radio is located close to the A/C and A/C wiring.
3. Locations where television and radio signals are weak.
Trouble :
1. Noise appears in the television picture, or the picture is distorted.
2. Static occurs in the radio sound.
Correction
1. Select a separate power source.
2. Keep the A/C and A/C wiring at least 1 meter away from wireless devices and antenna
cables.
3. Change the wireless device’s antenna to a high sensitivity antenna.
4. Change the antenna cable to a BS coaxial cable.
5. Use a noise filter (for the wireless device).
6. Use a signal booster.
13.1.5
Precaution, Advise and Notice Items
13.1.5.1
High voltage in Outdoor unit controller
Whole controller, including the wires, 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.
13.1.5.2
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 one minute after
turned off. Touching the Outdoor unit controller before discharging may cause an electrical shock.
When open the Outdoor unit controller cover, don’t touch the soldering pin by hand or by any
conductive material.

13.1.6.
Advise:
Open the Outdoor unit controller cover only after one minute from power off.
Measure the electrolytic capacitors voltage before farther checking controller.
Additional advises
When disassemble the controller or the front panel, turn off the power supply.
When connecting or disconnecting the connectors on the PCB, hold the whole housing, don’t pull the
wire, there are sharp fringes and sting on shell. Use gloves when disassemble the A/C units.
