General
The new DNG DCI INVERTER ducted split unit range comprises the following RC (heat
pump) models:
•
•
•
•
•
•
DNG 50
DNG 60
DNG 80
DNG 100
DNG 72

Remote control compatibility
The DNG unit is compatible with remote controls RC3, RC4, RCW1, RCW2, RC7.
Unlike standard units (fix RPM) that are selected according to their nominal capacity to
overcome the maximum required load, DC Inverter units can be selected to a smaller
nominal capacity range unit.
It made possible due to the ability of inverters to reach a much higher capacity level
(indicated as Maximum Capacity) which is around 115-130% of the nominal capacity.

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 DNG18 only, for DNG24 – 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.
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 the indoor to the outdoor by communication, and represented by a parameter called
‘NLOAD’. NLOAD is an integer number with values between 0 and 127, and represents the heating
or cooling load indicated by the indoor unit.
12.1.1
12.1.1.1
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 LOAD
calculation, the indoor fan speed, and the power shedding function.
NLOAD limits as a function of indoor fan speed:

Target Frequency Setting for DCI 72/80
The compressor Target Speed is calculated according to the following formula:
ODUNload T arg et Speed load max MinSpeed , MaxSpeed 127

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.

EEV (Electronic Expansion Valve) Control
EEV Control for DCI60
EEV opening is defined as EEV = EEVOL + EEVCV.
EEVOL is the initial EEV opening as a function of the compressor frequency, operation mode, unitmodel
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 temperatureis
set depending on frequency and outdoor air temperature, and the actual compressortemperature is
compared to the target temperature to set the required correction to the EEVopening.

Judgment by Indoor/Outdoor Unit Diagnostics
Enter diagnostics mode - press for five seconds Mode button in any operation mode. Acknowledgment
is by 3 short beeps and lights of COOL and HEAT LED’s. Then, every short pressing of Mode button
will scroll between Indoor and Outdoor unit diagnostic modes by the acknowledgment of 3 short
beeps and lighting of COOL and HEAT LED’s.
During the Outdoor unit diagnostics all four Indoor LED’s (STBY, Operate, Filter and Timer) are
blinking. When Indoor diagnostics is displayed, all four LED’s (STBY, Operate, Filter and Timer) are
ON.
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 LED
will blink during the same 5 seconds according to the following Indoor / Outdoor unit tables:
Note: 0 – OFF, 1-ON

13.1.7
13.1.7.1
Simple procedures for checking the Main Parts
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).
13.1.7.2
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.
13.1.7.3
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:
Between red wire and black wire: 310VDC +/- 20V
Between orange wire and black wire: 15VDC +/- 1V
Between yellow wire and black wire: 2-6VDC
13.1.7.4
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).
13.1.7.5
Checking the Reverse Valve (RV).
Running in heating mode, check the voltage between two pins of reverse valve connector, normal
voltage is 220VAC.
13.1.7.6
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.

Precaution, Advise and Notice Items
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.
13.1.9
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.
13.1.10
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.

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
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).
13.2.5.2
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.
13.2.5.3
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
13.2.5.4
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.
13.2.5.5
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.
13.2.5.6
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.
13.2.5.7
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).
13.2.5.8
Checking the termistors
Check Thermistor connections and wiring - Repair if needed.
Check Thermistor resistance – between 0ºC and 40ºC should be between 35KΩ and 5KΩ.
13.2.5.9
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
13.2.5.10 Checking for electromagnetic interferance (EMC problems)
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.
13.2.5.11 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.

Precaution, Advise and Notice Items
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.
13.2.6.2
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 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.

TROUBLESHOOTING
13.2.6.3
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.
